Prepare for Factoring Block (Algebra)

Learning Goal: Get ready for factoring by practicing with factor pairs and factor thinking. This is a (ideally) a two-player game.

Game Setup: There is a gameboard, a set of game tiles, and two sets of player ID cards (one set is X, one set is =). It is very important that the game tile pages get printed back to back on cardstock so that when it is cut out, you might see correct pairs as the front and back of a card. The player cards (= or x) should NOT be printed double sided. Print the two pages of game tiles on different colors for easier sorting of levels.

1. Place all the game tiles on the gameboard (see note about levels below). 2. Players take turns declaring the answer for a card, then checking it. If they are correct, they get to stake a claim on the space. If they are incorrect, their opponent gets to claim the space. 3. The goal is to place four player ID cards on the board in a row, column, or on a diagonal.

Level 1: Use the cards that only involve numbers.
Level 2: Use the cards with variable expressions.

Using Who Has? Decks to Practice Basic Facts
Once students have developed conceptual understanding of the basic operations they need to develop fluency with the facts.   One quick way to include daily practice and motivate students to master these basic facts is through the use of the Who Has? card decks.   These decks can be created for virtually any topic and frequent use as both a whole class practice or as a center activity for partners or small groups will provide facts practice in a highly-motivating format. Classroom Management Strategies

There are several strategies that have proven successful when implementing this activity: * Distributing Cards:   Distribute one card to each student, then distribute the extras to strong students in the beginning and to random students as the class becomes more familiar with the deck. * Class Play:   As you distribute the cards, encourage...
