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.
