Operations+with+Integers-m8h7

- A quick review of adding integers. I model how to use integer chips to add integers with the same sign, they try several problems, and then write a rule using the terms "absolute value" and "sign". Then we do the same with integers with different signs.

-A short extension activity for students where they create integer problems that have a given sum.

-A quick review of subtracting integers...I use chips to model the subtraction problems at the top, including adding in zero pairs when necessary. Students generally notice (especially with 7 - (-2) =9, that the solution is the same as 7+2. We talk about how to change the other problems to addition, and then write a rule.

- Exploration activity- Students look at examples of solutions to multiplying or dividing two integers with the same sign and develop a rule. Then they look at examples of multiplying or dividing two integers with different signs and determine a rule for that as well. The back of the activity extends into powers of integers and evaluating algebraic expressions with multiplication, division, and powers.

-Activity where students worked in groups of 3 or 4 to connect what they know about integer operation rules and adding/subtracting/multiplying fractions and decimals. I printed these on cardstock and cut them into 6 different "cards"- one for each topic. The groups worked on one topic at a time, and when they came to a consensus on all three questions they would come up and check with me. It ended up being a really good reinforcement of the integer rules, as well as a reminder of how to work with fractions and decimals.

It is pictionary, but with integers! Basically it runs like this.
 * The teacher has a list of x number of worked out equations involving integers (ex. (-3)+(+2)=(-1)) written on a piece of paper.
 * Students in pairs/groups send one person who is the "drawer" to see the equation.
 * Students return to their group, where on one mini white board they draw the equation (using a number line or [|army men] [what lesser people call "integer chips"]).
 * Other students in the group use their own mini whiteboards to write down the equation exactly.
 * When students correctly answer on their whiteboard they send the next student up to the front to receive an equation.
 * The process continues until all teams are finished (if you are into rewards give the top team some candy or something).
