standard_description: Generate two numerical patterns using two given rules. Identify apparent relationships between corresponding terms. Form ordered pairs consisting of corresponding terms from the two patterns, and graph the ordered pairs on a coordinate plane. For example, given the rule “Add 3” and the starting number 0, and given the rule “Add 6” and the starting number 0, generate terms in the resulting sequences, and observe that the terms in one sequence are twice the corresponding terms in the other sequence. Explain informally why this is so.

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.
