GEOMETRY – 2D Patterns PHOTOGRAPHS – Tribal textile patterns

What a beautiful way to investigate patterns and design. People have been creating magnificent geometric patterns for 1000s of years. Wandering nomads weave camel and sheep hair to produce rugs, and those closer to big towns spin silk and weave intricate designs – clothes, decorations for the house, cloths for rituals. Here are plenty of examples of tribal textiles  to start a conversation with your students.

Are the designs symmetrical? How many different colours are used? Are the designs simple or complex? Who might create such a textile? How long might it take them to weave or embroider?

Follow up in your own classroom by decorating some placemats or decorated cloths. Try creating some simple weaving frames and weave coloured wool.


MEASUREMENT – TIME PHOTOGRAPHS – iphones, wristwatches and digital clocks

It’s always a good idea to discuss time concepts daily – whether you teach Kinder or Year 6. Digital time is everywhere and most of the latest gadgets only show digital examples of time passing.We just uploaded 6 new photographs to help with your class discussions.

Elect one student to be your weekly time monitor. As a class, decide on a  list of times for your focus this week. Ask the time monitor to let everyone know when this time is approaching e.g. afternoon for Kinders, 1:30 pm for Year 1, a quarter to 11 for Year 2 and so on. We also have a great range of quick daily mental warmups for time. I love the Numberless Clockface cards. Try them today with your class. We include teacher instructions to get you started.


NUMBER & ALGEBRA – PLACE VALUE GRAPHICS – Skateboard digits

To start the year off we have just uploaded a brand new set of 1 – 9, 10 – 90, 100 – 900 and 1000 – 9000. They are all based on Duffy’s new set of Skateboard Robots. Heavens knows where he gets all his crazy ideas from but they look brilliant and should be a great way to focus on Place Value and Whole Number concepts in Term 1.

How many different ways can you talk about 3000?

Skateboard 3000 John Duffield duffield-design

 

e.g. 1 more than 2999, 1 fewer than 3001, 3000 ones, 300 tens or 30 hundreds. It is a multiple of 2, 5 and 10. It is also a multiple of 3 and 6. It is also a multiple of 4 and 8. But it is NOT a multiple of 9, 11 or 12. Half of it is 1500, Double 3000 is 6000. Ten times more would be 30 000. 3000 mL of orange juice is the same as 3 litres. 3000 m is the same as 3 km. 3000 square metres is the same as 3 tenths of a hectare.

What else will your students think of? Use a 1 minute time limit and challenge them to discuss their ideas with a partner.

Create a class book to share at the next school assembly.

Create a financial plan to raise $3000 over the year for your favourite school charity. e.g. We have 40 weeks so that’s $75 per week or $15 per day. What can we do to earn that much money?


NUMBER GRAPHICS – NUMBERS & SYMBOLS – Robot Skateboarder Digits 0 – 9

Wow, Duffy has really gone crazy. He has created this delightful set of robots that are all skateboard fanatics. They look like they are in a frantic skateboard race with their bodies forming the digits  0 – 9.

Use them in a wide variety of classroom activities. Make 3, 4, 5, 6-digit numbers to discuss as part of your daily Maths Mental Warmups. Add them to an activity card.

e.g. Did you know that 4840 is the number of square yards in an acre? This is an old imperial measurement from the time of the British. In Australia we now measure area in hectares, as part of the SI measurement system. An acre is now 0.405 hectares.

NUMBER & ALGEBRA – FRACTIONS & DECIMALS – If this is one unit (Stage 3 Fraction Cards)

Fractions are a nightmare for students. I am not sure why this is,  as underneath it all fractions are just another way to look at objects, by breaking them into smaller parts. The complication comes when we don’t visualise the link between objects and numbers. Fraction numbers without any link to objects in the primary school can be disastrous. To help your students visualise equal parts of shapes, we have created this activity called, “If this is one unit, then what is that?”

We think it will best suit Stage 3 students, but try it with Stage 2 as well. All you need to do is imagine inside your head how a smaller 2D shape can be combined to create a larger 2D shape.

For example, look at this yellow square, if this is one unit, then how does this unit shape relate to the blue trapezium? Can you mentally visualise how the yellow square will fit onto the blue shape? If so, what part is left? What part of another yellow square does this represent?

fraction-shapes-square-john-duffield-duffield-designfraction-shapes-trapezium-john-duffield-duffield-design

Can you see that it is a whole yellow square plus half of another one? So this blue shape is 1 and a half times the area of the yellow square.

What about this green trapezium. How many yellow squares could fit onto the same shape?

fraction-shapes-trapezium2-john-duffield-duffield-design

Can you see that it is the same as two yellow squares? One yellow square fits in the middle. The other yellow square could split in two and fit to cover the ends.

This activity contains plenty of discussions like this one to help your students imagine multiples of areas, multiples of fraction units.

We have also added the graphics separately for you to use any way you wish. See Fraction & Decimal GRAPHICS.

Please note that we have included suggested solutions to each of our Fraction Questions.


MULTIPLICATION & DIVISION – PHOTOGRAPHS – 30-legged creature

Arghh! This creature was crawling along our car port ceiling when I took this photograph of a 30-legged creature. We counted  … and think we see 15 pairs of legs. What a different way to discuss multiples of 2 with your Stage 1 students.  What if there were 2 creatures like this – how many pairs altogether? How many legs is that? How do you know? How many legs on 5 creatures? 10 creatures? 100 creatures? What is an easy way to help you count by 30s? e.g think of your groups of 3 tables facts and add a zero? Quickly add on mentally by 30 each time?


GEOMETRY – 3D PHOTOGRAPHS – Cylindrical crab hole

We are surrounded by 3D objects. Even creatures can create them. This photograph of a crab hole was taken yesterday at Bennett’s Beach, Hawks Nest. The beach was covered with these 3D spaces, built by industrious sand crabs, almost perfect cylinders.

cylindrical-crab-hole-bev-dunbar-maths-matters

These crabs are quite elusive and spend most of their time hidden underground. Did you know that a sand crab, unlike other crabs, can only move backwards? They have no claws on their front pair of legs. They feed in the wash zone where the tidal waves go up and down the shoreline. Sand crab tails also have the largest number of sensory neurons so they are often used in lab studies. And female sand crabs can lay up to 45 000 eggs at a time, even though most eggs do not survive..

NUMBER & ALGEBRA – PLACE VALUE from 100 PHOTOGRAPHS – 108, 8300 & 8765

It is always a good time to discuss Place Value with your students. Place Value is one of the biggest ideas in Primary Mathematics. Thanks to the use of Hindu-Arabic numerals and the creation of zero, your students can explore the power of Base 10 in all its beauty.

We just added 3 more number shots to our Place Value from 100 Photographs:

108-house-number-bev-dunbar-maths-mattersnumber-8300-bev-dunbar-maths-matters  number-8765-bev-dunbar-maths-matters

What will your students talk about?

e.g. 8300: What does each digit represent? What does this number look like in Base 10 blocks? How many i the 1s place, 10s place, 100s place, 1000s place? What is the total number of 1s, 10s, 100s, 1000s in this number? What is this number rounded to the nearest 10, 100, 1000 or 10 000? What if I took 1000 away? 5000 away? 8000 away? How many more to make 10 000? 20 000?  What could you buy with this if it was money? If you were a shop owner, how many $100 skateboards could you buy with this amount?

If these are centimetres, how many netres is that? How many kilometres? If these are square metres, how many hectares is that? If these were millilitres, how many litres is that? If these were kilograms, how many tonnes is that? If these are seconds, about how many minutes is that? About how many hours?


MEASUREMENT – VOLUME & CAPACITY – Photographs – Teapots

Teapots galore. These four teapots are from my personal collection of over 300 teapots.

A fun way to talk about volume with primary students. How many cups does each one hold? If you filled it up 4 times how many cups of tea can you serve? Which teapots hold more, the same or less tea? What’s the smallest teapot in the world look like? What does the largest teapot in the world look like?  If one teapot holds 5 cups how many times will you need to fill it to serve 2 cups of tea to 6 people?

I’m sure you and your students will create many more teapot problems to solve.


MATHS GRAPHICS – Numbers & Symbols – Water Digits 0-9

Duffy has just uploaded this beautiful set of 0 – 9 Water Digits. We used them to create our latest set of Sea Creatures 1 – 10 Posters. Use them with Early Stage 1 students as a stimulus for drawing and counting their own sea creatures 1 – 10. Or create 2-digit to 6-digit numbers on your smartboard with older students, as part of your daily mental warm-ups. Challenge everyone to create matching facts about water e.g. 495 – 495 L is almost 500 L of water or half a tonne, 495 mL is almost half a litre of water, 505 L more would make a tonne.


MATHS GRAPHICS – Creatures – Sea Creatures

Duffy is creating a delightful set of sea creatures for you. There will be at least 10 and when he is finished we will create a set of Sea Creatures 1 – 10 Counting Posters. Remember to use our resources in a variety of ways, not just for maths.  They may be the stimulus for a set of stories or poems. They may be part of a Science unit on the effects of humans on the sea.

Each illustration can be used for online research too. What are all the maths facts your students can discover about each creature?

e.g. Sea turtles:

  • Australia has some of the largest marine turtle nesting areas in the Indo-Pacific region.
  • Australia has the only nesting populations of the flatback turtle.
  • Raine Island, in the northern Great Barrier Reef, is home to the world’s largest green turtle rookery, with an annual nesting population of 30 000 female turtles.
  • Marine turtles have lived in the oceans for over 100 million years.
  • Adult Green Turtles have a shell length of about 1 m and their average mass is about 130 kg.
  • Green Turtle hatchlings are only 5 cm long with a mass of 25 g.
  • Green Turtles lay about 115 eggs per clutch, and produce about five clutches per season.

MATHS GRAPHICS – Counting – Wild Animal 1-10 Posters

Ten leaping cheetahs – just one of our new Wild Animal Counting 1 – 10 Posters. Young students need plenty of variety to develop flexible number concepts. Apart from the obvious counting of all the creatures on each poster, challenge your students to visualise adding and subtracting creatures too. What if three more cheetahs joined these ones – how many cheetahs will there be? What if 10 more joined? What if 3 cheetahs were too tired and stopped to take a rest?

Encourage your students to create these “What if?” stories for each other.


WHOLE SCHOOL PLANNING – Maths Improvement Plans – Term 1 – Number Resources Checklists

We’ve had many requests for us to create Number Resources Checklists and have just uploaded one for each Stage. We tried to link each item in the list to any existing resources we supply, but could only link it to the general page, not the specifc item. At least this shows you which page to look at. As you can see, there are plenty of items that we think are essential for effective mathematics teaching. Resources to use as large flash cards for whole class discussion, for example. Perhaps you can make at least one set and share it with another class.

We are constantly creating more resources so these checklists will be updated at the end of each term. If you can see any items you think are still missing, please write to us and we will do our best to create what you need. Our aim is to provide all the essential resources that will make your teaching life a breeze. We want you to love teaching mathematics and see it as a highlight of your day. And of course we want your students to have the resources they need so that they love maths too and understand how it fits into daily problem solving in their own lives.


MATHS GRAPHICS – COUNTING – Multiples of 100 Alien Eyes

Stage 1 students will love counting multiples of 100 when it is all about Alien Eyes. We need to provide our students with a wide variety of Base 10 models to help them develop a flexible image of how our Place Value system works. This set of 100 – 900 posters is just one resource we provide. In Place Value Graphics there are also single aliens with one eye, single aliens with 10 eyes and then a spaceship full of 10 aliens who each have 10 eyes.


MATHS GRAPHICS – COUNTING – Multiplication & Division Arrays

These colourful new Multiplication & Division Arrays will help you talk about number facts and number patterns with your students. For example, 10 groups of 4 triangles are the same number as 4 groups of 10 triangles. It’s also the same as two groups of 2 x 10 triangles. Or the same as two groups of 4 x 5  triangles. What more can your students discover?


MATHS GRAPHICS – Fractions & Decimals – Decimal Number Expanders and Decimal Place Value Charts

We have been revising our Graphics section and just added heaps of new resources to help you with Fractions and Decimals. We have Decimal Number Expanders ( so your students can create their own decimal number and describe them to a partner), Decimal Place Value Charts (so your students can create random decimal numbers using either a spinner of digit cards, then describe and compare these with a partner), Fraction Posters (e.g. thirds of a cake, fifths of a beaker of liquid) (so your students can more easily visualise what different amounts look like). Plus we improved our Fraction Cake graphics so that your students can “see” the missing parts of the whole cake. Again, this should help them more easily visualise what each fractional part looks like.


MATHS GRAPHICS – Place Value – Spinners

Even though they might not work as effectively as a plastic commercial spinner, have a go at making your own Place Value Spinners with your students. All you need is a photocopier, A4 Cardboard sheets, scissors and a split pin. We have created a variety of colours and a range of values from 0, 1, 2 … 9, 0; 10, 20 … 90; 0, 100, 200 …900 and 0, 1000, 2000 … 9000. Plenty to keep your students happy creating random numbers for their activities. What are you waiting for?


COUNTING GRAPHICS – Multiples of 10 to 90 Sheep Posters

Counting by 10s is one of the essential early counting skills. Practise counting by 10s with your Early Stage 1 (Kinder/Reception/Prep) students daily. You can stand up and jump as you count. Or clap your hands and then your heads as you count by 10s. Anything to get them moving rhythmically whilst they count. These Multiples of 10 – 90 Counting Posters will help you consolidate this oral counting with representations of groups of 10. Stop at one multiple and check that students can say the multiple before or the multiple after that number. Or ask them to count by 10s while you clap your hands. When you stop they whisper the number they are at to a friend.


LENGTH PHOTOGRAPHS – 14 new resources

We’ve been focussing on our length resources this week. Duffy is drawing 4 sports people (coming soon) and I’ve just uploaded 15 new Length Photographs. Many of these are items you use to measure both informal and formal length. Use them as part of your introductory discussion to a length unit. Many people are unfamiliar with the formal equipment. What can you use this item for? What has it got to do with length? Where do you start and finish your measurement? e.g. this photo shows a Diameter Gauge. Notice the measurments are smaller at the lower pointy end and larger at the wider section. This makes sense when you put this object into the top of an open container, such as a jar. It is one way to measure the inside diameter. Always encourage our students to estimate the diameter first, before they start to measure.


MATHS GRAPHICS – CREATURES – Alpaca and friends

Duffy has been hard at work creating 4 new farm animals for me to use on my new Algebra Animal Antics Level 1 Stage 3 activities. I just flick my fingers and demand a creature, then voila, they suddenly appear ready for all of us to use. He is SOOOO clever! Duffy’s favourite is the alpaca (he knows I love these in real-life too). My favourite is the duck. Which new creature do you like best?

Farm - Foal - John Duffield duffield-design Duck - John Duffield duffield-design Lamb - John Duffield duffield-design

 

We have also created a set of cute 1-10 Farm Animal Counting posters. You can find these all together in F/1/2 Counting Activities or separately in Counting Graphics.
