ACTIVATOR (1) Pick up a new packet (MODULE 4)! (on top of projector) (2) Write your name, date, and class on front cover. (3) Copy and solve this on page 1 of packet (anywhere is O.K).: a.2 – 2 + 3= _______ b – 10 = ______ c – 11 = ______ Feb. 23, 2015 Module 4: Lessons 1-2 -(-5)
ACTIVATOR Copy and solve this on page 1 of packet: a. 2 – 2 + 3= _______ b – 10 = ______ c – 11 = ______ Feb. 23, 2015 Module 4: Lessons 1-2 -(-5) (anywhere is ok) “when a number is added and subtracted by the same number, the result is the original number”
OBJECTIVE(S): Feb. 23, 2015 Module 4 SWBAT: recognize when a number is added and subtracted by the same number, the result is the original number (Lesson 1) a + b – b = a or b – b + a = a recognize when a number is multiplied and divided by the same number, the result is the original number (Lesson 2) a ÷ b b= a or a b ÷ b = a 6.EE.A.3
Feb. 23, 2015 Module 4 Lesson 1: write this on page 3 The relationship between Addition and Subtraction v + 4 – 4 =_____ b. 450 – = _____ 16 + m – 16 =____ c ____ = 1289 a. ____ + 15 – 15 = 21 v m (anywhere is ok)
Lesson 1: write this on page 3 The relationship between Addition and Subtraction addition subtraction “when a number is added and subtracted by the same number, the result is the original number” (opposite)
Classwork: pg. 2 (#4 – 5 only) -(-5)
Classwork: pg. 2 (#4 – 5 only)
Feb. 23, 2015 Module 4 Lesson 2: pg. 4
Go to: pg. 5 Write this anywhere on the page: ÷ 4 x 4 = _______ 2. 3 x 10 ÷ 3 = _______ ÷ ___ x 7 = _____ x 2 ÷ 2 =
Classwork: pg. 5 (# 1 & 2) Both relationships create identities. when a number is multiplied and divided by the same number, the result is the original number
topic. How do you feel? Feb. 23, 2015 Module 4: Lessons 1-2
Lesson 3: go to pg = 15 and 3 × 5 = 15 Multiplication is repeated addition.
Classwork: pg. 7 (all) 5 minutes
Notes: pg. 8 ( #4 only) COPY THIS onto PACKET! The equation is true b/c it shows the addition identity. The equation is true b/c it shows the subtraction identity. x + 0 = x 2f - 0 = 2f

Feb. 23, 2015 Module 4 Lesson 4: Division Subtraction What two operations are we relating in the problems we completed? Division and Subtraction
Pg. 11 (Exercise 1) – NOTES 35 – y – y – y – y – y = 0 42 – z – z – z – z – z – z = 0 18 – x – x – x = 0
Pg. 11 (Exercise 1) – NOTES (cont.)
Pg. 12 (Exercise 2) – NOTES 12 – x – x – x = 0 Subtracted “ x” three times x = 4 36 ÷ 4 = f or 36 ÷ f = 4 24 – 12 – 12 = 0 Two f = 9
