Adding and Subtracting Integers (on ASSISTments)

# Today in Class

Class started with a discussion of ways that students solve addition and subtraction integer problems without the use of chips or number lines. Students came up with some interesting ways to solve and Mr. Burnett sang them a song (that he made up to the tune of Happy Birthday) to help them when solving. The lyrics are:

“With the same you sign you add,

with different signs you subtract.

And the last thing to remember,

take the sign of the bigger number.”

After the discussion, students played a card game with integers. Here are the rules.

If students had a hand that looked like the one below, their hand would total of -3. Students had to decide whether to take the Jack or pick from the top of the deck and then which card to replace.
