You will need: a ruler, some objects to measure - we have done this with leaves, seaweed, sticks etc. You might also want a clipboard (or something to lean on), a piece of paper and a pencil.
Plan a walk somewhere. Decide what you are doing to measure on your walk. Take a ruler with you. On your paper, you need to identify sizes. We wrote:
'big' around 13 cm
Medium around 8cm
Small around 5cm
Tiny around 3cm.
Measure each item you find on your walk. Create a tally as you measure. How many of each size did you find? My children enjoyed making groups of 5 and 10, collecting them too.
Once you return home, you might want to create a bar chart to extend the activity.
