Answer (1)
To decompose the number 5 into two groups of balls, you can split the 5 balls into pairs of numbers that add up to 5. Here are the possible pairs:0 and 51 and 42 and 33 and 24 and 15 and 0For drawing, you can draw the 5 balls, then circle or separate them into any two groups corresponding to one of these pairs, and write the numbers in the boxes as the count for each group.Example: Draw 2 balls in one group and 3 balls in the other, then write "2" and "3" in the boxes.This is called decomposing the number 5, breaking it into two smaller numbers that add up to 5.
