Seven apples are counted one at a time and then put onto two plates, 5 on one and 2 on the other, and counting them all again checks that 5 and 2 make 7. One apple then moves across to make 4 and 3, the count again comes to 7, and the video ends on two ways to split 7: 5 and 2, or 4 and 3.

Concept: Splitting a number into two parts: 7 is 5 and 2, or 4 and 3

Put 5 apples on this plate.

Put 2 apples on that plate.

Count them all: 1, 2, 3, 4, 5, 6, 7. 5 and 2 make 7!

This plate has 4, and that plate has 3.

Count them all again: 1, 2, 3, 4, 5, 6, 7. 4 and 3 make 7 too!

Two ways to split 7: 5 and 2, or 4 and 3.
