Narrative
Before playing, students remove the cards that show 10 and set them aside.
Each student picks 6 cards and chooses 4 of them to create an addition expression with fractions. Each student adds their numbers and the student whose sum is closest to 5 wins a point for the round. Students pick new cards so that they have 6 cards in their hand and then start the next round.
Variation:
Students can choose a different number as the goal.
