Subtraction Games

Today in math First Graders played 2 familiar games, but with a new twist!  They played "Roll and Record" and " Five-in-a-Row" with subtraction.  Students used two dice to play, one was a cube with numbers 7-12 on it, and the other was a regular die with dot patterns for the numbers 1-6.  After rolling the dice, they would put the larger number in their head and count backwards as they touched each dot on the other die.  They could also use a number line to "jump" backwards the amount of dots that they had rolled.  They also needed to record each of their equations as they worked.  They all did a great job with these games!!  We ended with a discussion about what strategy worked best for them, and why.
