adding integers
03012012, 04:40 PM


I make a walkable number line on my floor, that we then we use it to model addition and subtraction of positive and negative integers.
They stand on the first number and if they are adding, face the positive end and if they are subtracting they face the negative end.
Then, they walk forward if the second number is positive and walk backwards if it is a negative number. They end up on the answer.
Then, we transfer this same skill to a small number line on their desk. It really helps my kiddos learn this skill. I see them turn their bodies a little in their seats to "remember" how to do it.
