standard_description: Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.
Grade 4 expectations in this domain are limited to fractions with denominators 2, 3, 4, 5, 6, 8, 10, 12, and 100.

Narrative
Before playing, students remove the cards that show 10 and set them aside.
Students spin the spinner to get the divisor for the round. Each student picks 6 cards and chooses 3–4 of them to create a dividend. Each student finds their quotient. The score for the round is the remainder from each expression. Students pick new cards so that they have 6 cards in their hand and then start the next round. The player with the lowest score after 6 rounds wins.
