Student Section Summary
We learned that division is finding the number of groups or finding the size of each group when we put objects into groups of equal size. We represented division situations with drawings and expressions, and solved division problems.
“How many groups?”
“How many in each group?”
Han has 12 pencils to put in boxes. He wants to put 2 pencils in each box. How many boxes does Han need?
Elena has 12 pencils to put in 2 boxes. She wants to put the same number of pencils in each box. How many pencils should Elena put in each box?
Both expressions have the same divisor, 2. However, the 2 has a different meaning in each situation.
