Measuring

Make a selection of worms using a material at home e.g playdough, string, paper. Using a ruler measure your worms in centimetres. How long are they? Which is the longest? Which is the shortest? 

Challenge:

Try comparing 2 worms of different lengths. How much longer/shorter is one worm than the other? How would you work this out? Can you show me by writing a number sentence?

Number

Can you do some worm maths? To make this activity a little more tricky, ask a grown up to write you some addition sentences. Can you work them out using your fingerprints?
