Extending Skip Counting using CCSS

The ultimate goal of skip counting and/or arrays is to help students consider the possible factors of any number. Extend the real-life array and skip counting by asking the questions below.

• How many popsicles are in the box?
• What are the possible arrays for this box of popsicles?
• Which array or arrays are most likely for this box? State your reasoning.
• Do you think the popsicle make would create a box for 1 row of 18 popsicles? Why or why not?
