Balanced Math Planning Date: ________________________________ Amount of Time: _____________________________ Strand: Number Sense and Numeration Expectation: Solve problems involving operations with integers using a variety of tools Big Idea: Solving problems involving integers using a variety of computational strategies Minds On Open Question Show -12 as a sum of other integers. What is the largest value you can use for the other integers? What is the smallest value? Action SMARTboard Math Facts Math Games Shared Problem Solving (2) Guided Problem Solving Balanced Math Centres http://nlvm.usu.edu – number line bounce Math Trek 7/8 – Whole Numbers and Integers Card game – red cards positive, black cards negative Practice adding and subtracting pairs of cards Use a number line to verify answers Integer War https://www1.scdsb.on.ca/portal/page/portal/STAFF/SW_TEACH/Pro gram/Numeracy/Elementary%20Math/Instruction/Intermediate/Num ber%20Sense%20and%20Numeration/Integer%20War.pdf Integer Race https://www1.scdsb.on.ca/portal/page/portal/STAFF/SW_TEACH/Pro gram/Numeracy/Elementary%20Math/Instruction/Intermediate/Num ber%20Sense%20and%20Numeration/Integer%20Race%20Rules.pdf Integer Race Game Board https://www1.scdsb.on.ca/portal/page/portal/STAFF/SW_TEACH/Pro gram/Numeracy/Elementary%20Math/Instruction/Intermediate/Num ber%20Sense%20and%20Numeration/IntegerRaceGameBoard.pdf Which of these calculations do you see as most alike? Why? -3.4 + 5.7 = 1.7 3/5 + 2/3 = 1 4/15 3 ½ + (-4/3) = 2 1/6 What did Tom Write? Tom wrote down two positive integers consisting of the following digits: 1, 2, 3, ,4 ,5, 6. Each of the digits appeared in only one of the two numbers and only once. When tom adde4d up these numbers he obtained 750. What positive integers did Tom write? For lower students: demonstrate on a number line and using algetiles that adding opposite integers always = 0 For other students: You are using an elevator in your hotel, you go up 8 floors (ground floor is the first floor), the door doesn’t open and you need to go down two floors. Use a number line to demonstrate where you end up. Laptop Activities http://www.hoodamath.com/games/integer.html Consolidation Consolidation: Journal: You add two numbers and the answer is negative. What two answers might you have added?
