For a math center or early finisher: Write a single digit addition sentence on each cooler and print and cute enough ice creams to solve the additions. I recommend printing and pre-writing at least 6 and cutting 20 ice creams. Students will then solve the addition sentence using the ice cream.
For small group: Print and laminate one cooler for each student and enough ice creams for all of them to solve the addition. Have them write the addition sentence on the cooler using a dry erase marker and let them solve it. repeat.
