This is a lovely little activity focussing on a number of skills in a fun way.
You will need: a ruler, a pen (or chalk), leaves, paper or a patio.
Go on a mini scavenger hunt around the garden. How many different leaf types can you find? If you are planning a walk or some exercise, then you might want to collect other leaves along the way.
On a piece of paper (or on a patio), place the leaves in size order. Then, using your ruler, measure the length of the leaf and write it below.
