Exploring how to decompose numbers in more than one way

Count the green dots mentioned in the upper section of each box and write the number value inside the green circle shape. Break that total value in one more way and represent the number equations with red dots in the below given boxes as shown the first box.

On the sheet

Features four panels with green dots to count and decompose. The first panel is complete, showing 3 + 1 green dots (total 4) decomposed as 2 + 2 red dots. The other three panels show green dots (4 + 2, 5 + 3, and 6 + 3) with empty circles and boxes for children to write totals and draw red dot decompositions.
