# NUMBER & ALGEBRA – PLACE VALUE GRAPHICS – Skateboard digits

« Go back

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?

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?
