Decimals Cruncher

Howdy!

Today you'll be playing a team game to practice what we've learned about multiplying with decimals. Display Decimals Cruncher on the Polyvision board (click this link): http://www.coolmath-games.com/decimals-cruncher/decimals-cruncher-multiplication.htm. Be sure to select the "hard" level option when playing the game. Please designate a classmate to keep score on the chalkboard.

Divide your class into two teams. Boys vs. girls worked well last time if you'd like to do that again. Take turns going up to the board to answer the questions with the eno pen. Remember to take a notebook and pencil with you - nooooo calculators!

Team 1 will send a player to the board to complete a problem. Correct answers score 1 point. Incorrect answers score no points. After the first player from Team 1 has gone, Team 2 will send a player to complete a problem. Then Team 1 will send another player, and so on, alternating between your two teams. The team with the most points at the end of the game wins. Have fun!
