Travail painful, arduous work

IWBAT add integers.

Integer – any positive or negative number, excluding fractions, decimals, or percents.

But I don’t know how to add integers!!! I think that I am going to …

No vorries children! Adding integers is not that different from adding whole numbers.

There are 3 ways that I use to add integers: 1.)Number Line 2.)Counters 3.)Song

To use the number line, follow these steps: 1.)Start at the point of the first number 2.)Then do one of two things: a)If the second number is positive, go to the right the number of spaces b)If the second number is negative, go to the left the number of spaces

Simplify: Move the point 7 spaces to the RIGHT 4

Simplify: 4 + (-5) Move the point 5 spaces to the LEFT 4

Simplify: Move the point 2 spaces to the RIGHT -3

To use the counters method, follow these steps: 1.)Make a T-Chart 2.)Use “+” signs to represent the positive number and “-” to represent the negative number 3.)Cross out every “+” that you have a “-” for 4.)Count what you have left. That is your answer. If you have more “+” left, your answer is positive; if you have more “-” left, your answer is negative.

To add integers, simply sing this song to the tune of Row, Row, Row, Your Boat:

I am Hall of Fame lineman Randall McDaniel. I wasn’t selected for 12 Pro Bowls and the Hall of Fame just because I went to Agua Fria High School. I got where I am now because of hard work and lots of practice. I most liked practicing using whiteboards.

It’s whiteboard practice time!
