Complete the grouping problems below. Show your addition sum, multiplication sum, and division sum for each.

Here are the completed grouping problems:

First set of green blocks (left)

• There are 4 groups of 6 blocks each.
  • Groups of: $\boxed{4}$ groups of $\boxed{6}$
  • Addition sum: $$6+6+6+6 = \boxed{24}$$
  • Multiplication sum: $$4 \times 6 = \boxed{24}$$
  • Division sum: $$24 \div 6 = \boxed{4}$$

Second set of green blocks (middle)

• There are 6 groups of 6 blocks each.
  • Groups of: $\boxed{6}$ groups of $\boxed{6}$
  • Addition sum: $$6+6+6+6+6+6 = \boxed{36}$$
  • Multiplication sum: $$6 \times 6 = \boxed{36}$$
  • Division sum: $$36 \div 6 = \boxed{6}$$

Red squares (right)

• There are 3 groups of 100 squares each (each large square is $10 \times 10 = 100$).
  • Groups of: $\boxed{3}$ groups of $\boxed{100}$
  • Addition sum: $$100+100+100 = \boxed{300}$$
  • Multiplication sum: $$3 \times 100 = \boxed{300}$$
  • Division sum: $$300 \div 100 = \boxed{3}$$
