This is a set of cards for helping kids to comprehend the idea of quantity and its association with the numbers.
For every number N from 4 to 10 there are 10 cards with two rows each:
- the left row contains N squares with 1 to N copies of various objects;
- the right row contains N squares with the numbers from 1 to N;
- the task is to connect object-squares with the corresponding number-squares.
My twins love this cards as the pictures contain their favorite objects.
