1 Jun 273:40 PM Lesson Objectives: • I can recognize and use zero pairs. • I can represent addition as a value model. Math 6/7 - Unit 2 Day 4 - Adding MORE Integers (pg 41 in INB) Jun 273:33 PM a. 5 b. -3 c. the opposite of 4 d. the opposite of -2 e. |3| f. |-3| Model and sketch a picture of the following integers. We can use algebra tiles to model the value of integers. 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Aug 71:19 PM a. 3 + 4 b. -5 + (-4) c. -2 + (-9) d. 7 + 1 Model and sketch a picture of the following expressions. Using algebra tiles to model addition, allows us to count the number of total tiles. 1 1 *What patterns do you notice?* 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Aug 71:25 PM g. 5 + (-5) h. -3 + 3 Model and sketch a picture of the following expressions. 1 1 A zero pair is when we pair one positive counter with one negative counter. Describe situations in which opposite quantities combine to make zero. 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Aug 71:35 PM i. 6 + (-3) j. 8 + (-7) k. -2 + 5 l. -4 + 9 Model and sketch a picture of the following expressions. (Be observant of patterns and short cuts.) Use zero pairs to help model expression that have integers of different signs. 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Aug 71:35 PM m. -5 + 2 n. -7 + 6 o. 3 + -4 p. 3 + -8 Model and sketch a picture of the following expressions. (Be observant of patterns and short cuts.) Use zero pairs to help model expression that have integers of different signs.
