Practising measurement skills is captivating with this race car themed activity!

After choosing their race cars, your students will decide which informal units to use to measure the distance travelled. The worksheet prompts them to consider why they chose the unit, whether the same one needs to be used for each measurement and what could increase accuracy.

A ramp is needed so that the cars can be released. This could easily be constructed using a stack of books with a larger, hardback book to form the main part of the ramp. Alternatively, constructing a ramp could be an additional STEM/Design and Technologies task that is completed before this activity.
