Signed Numbers: Colored Counters in a “Sea of Zeros”

The “colored counter” method is an old tried-and-true method for teaching the concept of adding signed numbers.  However, to show subtraction with the colored counter method has always seemed painful to me … that is, until I altered the method slightly. Now all problems are demonstrated within a “Sea of Zeros” and when you need to take away counters, you can simply borrow from the infinite sea.  Voila!  Here’s a short video to demonstrate addition and subtraction of integers using the “Sea of Zeros” method.  You can print some Colored Counter Paper here.

Exponent Block and Factor Pair Block

A few weeks ago I built two new games for algebra in one week.  These games just use the game mechanic from “Antiderivative Block” (a Calculus game), but with algebra-oriented game cards.  The game mechanic is a classic “get 4-in-a-row” so it’s pretty easy to learn. Exponent Block (plus Gameboard) will help students contrast slightly different expressions involving exponent rules, especially negative and zero exponents. Factor Pair Block (plus Gameboard) will help prepare students for a unit on factoring.  There are two sets of playing cards (print each set on a different color of paper if you want to...
