The math caterpillar calculates on from segment to segment.
The starting number is in the first circle.
Above every arrow it says what you have to work out.
Write the result in the next circle and carry on like that.
Example: start 30, then +10, then +20, then -5.
30 plus 10 is 40, plus 20 is 60, minus 5 is 55.
So the caterpillar shows: 30, 40, 60, 55.
The numbers filled in show the solution.
Example
For parents
What does this exercise practice?
Carry out several calculation steps in a row cleanly and keep using the in-between result.
Common pitfalls
Children often forget to carry on with the last result and take the starting number again. Tip: always look at the circle before.
How to practice at home
Think of a starting number and take turns calling out steps like plus 10 or minus 5. Who works it out faster in their head?
