Lesson objective: Apply skills with combining equations into one equation and representing a word problem with an equation by playing a game.

This lesson provides an opportunity for students to apply their knowledge and understanding of representing equations to a game situation. Students are asked to comtbine two equations into one, check a division problem for accuracy by using inverse operations, and to write an equation that represents a word problem.

Key Concept students will use:

- We can represent problem situations with equations, understanding that the operations shown in the equation may not be the operation we use to solve the problem.

Skills students will use:

- understanding of how equations can be combined by using parentheses
- check division problems that have remainders by multiplying and then adding the remainder.
- writing equations that represent word problems

Students engage in Mathematical Practice 2 (Reason abstractly and quantitatively) as they play a game with partners. The game will require students to record their responses to random game cards.
