Skills stimulated
Discovering math through play suddenly makes learning a lot more fun. With this material, children practice important math skills within the number range up to 20 in an active and visual way.
- counting forwards and backwards from 1 to 20
- recognizing quantities at a glance (subitizing)
- splitting numbers (for example, dividing 7 into 5 and 2)
- counting in jumps, such as 2-4-6 or backward 17-15-13
- discovering even and odd numbers
- recognizing and understanding neighboring numbers
- comparing numbers (<, > and =)
- practicing addition and subtraction up to 20 in a concrete way
- doubling and halving as a first step towards multiplication and division
- gaining insight into the 5- and 10-structure, an important foundation for math
By looking, stacking, splitting and comparing, number sense grows step by step. Children thus build a solid foundation for math in groups 3 and 4, while playfully discovering how numbers work.
