Children often enjoy using modelling clay to create long thin rolls of dough, like caterpillars.
Adults could support them to compare the lengths and thicknesses of their models and to use linked cubes to measure them.
The Activity
Provide children with modelling clay and pictures of caterpillars, and invite them to create their own caterpillars.
Provide children with modelling clay and pictures of caterpillars, and invite them to create their own caterpillars.
Encouraging mathematical thinking and reasoning:
Describing
What will your caterpillar be like? How can you make one?
Tell me about your caterpillar.
How is your caterpillar similar to/different from ...?
What will your caterpillar be like? How can you make one?
Tell me about your caterpillar.
How is your caterpillar similar to/different from ...?
Reasoning
Can you make a train of linked cubes the same length as your caterpillar?
How long is your caterpillar?
Who has made the longest caterpillar? How do you know?
Who has made the shortest caterpillar? How do you know?
Can you make a train of linked cubes the same length as your caterpillar?
How long is your caterpillar?
Who has made the longest caterpillar? How do you know?
Who has made the shortest caterpillar? How do you know?
Opening Out
How could you make a longer one?
How could you make a shorter one?
How could you make a heavier one? A lighter one?
How could you make a longer one?
How could you make a shorter one?
How could you make a heavier one? A lighter one?
Recording
Draw a picture or take a photo to show how long your caterpillar is.

The Mathematical Journey
Properties of shapes:
- using everyday language to describe, for example, length, weight, thickness, thinness, hardness and softness, and how these properties change as the children make the caterpillars
Same and different:
- developing language to compare and contrast different caterpillars e.g. longer, shorter, thicker, thinner ...
Size and measures:
- measuring lengths, weights etc. in different ways
- understanding that the more dough is used, the heavier the caterpillar will be
Development and Variation
Children are often fascinated by watching caterpillars. A caterpillar hunt might be a suitable introduction to the task.
Children might also compare:
The Very Hungry Caterpillar by Eric Carle is, of course, a popular and familiar story. It offers opportunities to make cross-curricular links and links to counting and number comparisons, as well as the order of the days of the week.

Children might also compare:
- lengths of different familiar objects such as shoes, scarves and skipping ropes
- weights of household objects and groceries such as pieces of fruit.
