  • The items in the store are hats, Jersey, Baseball Cap, T-shirt, Running Shoes, Shorts, and Sweat Pant
  • Copy and cut apart the paper manipulatives and put in clear bags.
  • Demonstrate how to select exactly two items from the six choices. Emphasize that the two items may never be identical (e.g.: they cannot select two baseball hats at the same time).
  • Have students work in groups to create all of the possible 2-item specials by selecting exactly two unique items for each bag.
  • Once groups are finished, demonstrate how to represent all of the combinations using a chart or organized list.
