Product Description
Middle school students learn to simplify expressions that are written in a horizontal arrangement such as . These cards have been designed to give students additional practice at simplifying those expressions using the order of operations.

The cards have been designed to be used in a class of 15, 20 or 25 students. A symbol, at the bottom of the cards can be used to sort the cards. If you use cards with a ♡ the set will make one cycle with 25 cards. If you use cards with a ♢ the set will make a cycle of 20 cards. If you use cards with a ♧ the set will make a cycle of 15 cards. Using the symbols you can quickly sort the cards into a set of 15, 20, or 25 cards.

Included in this activity are

1) A teacher’s master list of all 28 cards. The “I Have” for card 1 is not the answer to card 1. It is the answer to either card 15* , 20* or 25. The “I Have” for card 2 is the answer to card 1.
2) One set of 10 (♢), 15 (♧) , 20 (♤), or 25 (♡) cards.

There are several ways you can use these different sets of cards:

You need to use either the set of 15 cards (♧), 20 cards (♢) or 25 cards (♡) to complete a cycle.

How the activity works:

1. Distribute the cards (15 (♧), 20 (♢), or 25 (♡)).
2. Have anyone read their question for “Who Has” from their card, such as Who has ? It might be easier for the student who is reading the card to also write their expression on board so everyone can also see the expressions. The rest of the students try to solve it and then look at their card.
3. When someone discovers they have the answer to the question, they read their card.
4. This produces a new card and a new problem. The new problem is described and the class works on new problem.
5. This procedure continues until the last person reads their problem and it turns out to be the answer of the original first card.
6. This set of either 15, 20, or 25 cards can be used to give all your students additional practice with writing algebraic expressions.
