Lower Elementary:
Question: Ryan and Hannah built a lot of snowmen. Five of the snowmen were made with 3 snowballs and four of the snowmen were made with 2 snowballs. How many total snowballs were used to make the snowmen?
Solution: Since five snowmen are made with three snowballs, we can count by 5, three times to get the number of snowballs. 5, 10, 15. 15 snowballs were used to make those snowmen. Four snowmen are made with 2 snowballs, so we count by 4, two times to get the number of snowballs. 4, 8. 8 snowballs were used to make those snowmen. The total number of snowballs used are 15 + 8 = 23 snowballs.

Upper Elementary:
Question: A container has 2 cups of flour. Alex used 3/4 of a cup to make pancakes and then used 2/5 of a cup to make strawberry shortcake. How much flour does Alex have left?
Solution: After using the flour for the pancakes, there is 2 – 3/4 = 1 1/4 cups of flour left. After making the strawberry shortcake, there is 1 1/4 – 2/5 = 1 5/20 – 8/20 = 25/20 – 8/20 = 17/20 cups of flour left.

Middle School:
Question: Justine is 48 inches tall and casts a 5–foot shadow. The tree next to Justine is 10 feet tall. How long is the shadow that the tree casts in feet?
