To solve this worksheet, we need to look at each group of boxes. In every group, there is a number on top and two boxes on the bottom. The box on the left has some dots (like a die), and the box on the right is empty.
The rule is:
The number on top is the total sum.
So, we take the top number and subtract the number of dots we see to find out what goes in the empty box.
Here is the step-by-step solution for each row:
Row 1:
1. Top number is
5. Left side has
3 dots.
* Math: $5 - 3 = 2$.
