2 x 4= 8
2 + 2 + 2 + 2 = 8
4  x  2  = 8
Think boards encourage you to solve problems in many ways. This think board has 4 ways. Commutative property: to change the numbers round if you think this is going to be helpful in solving the problem. Repeated addition: use an addition strategy to solve the problem like the one in the example. An Array: line up your materials in lines that form the required number needed. Groups of: put your problem into groups that represent how many groups and how many you need inside the groups.Try your best .
