a + 2 = 8 Activator: Take out your homework & notebook. March 25, 2015 [Day C] Take out your homework & notebook. In notebook copy and solve this equation: a + 2 = 8

solve one-step equations by relating an equation to a diagram. March 25, 2015 [Day C] Objective(s): SWBAT: solve one-step equations by relating an equation to a diagram. check to determine if their solution makes the equation true. (6.EE.B.5)

Notes in NB: March 25, 2015 [Day C] a + 2 = 8 Draw two tape diagrams that are the same length. 8 2 Label the first tape diagram 8. Represent 2 on the second tape diagram.

Notes in NB: March 25, 2015 [Day C] Draw another set of tape diagrams to represent the given equation: a + 2 = 8. Because both of the following tape diagrams represent the same value, what would the value of “a” be? Explain. The parts that have a and 6 must represent the same value. Therefore, “a” must have a value of 6.

What actually happened when constructing the tape diagrams? March 25, 2015 [Day C] Using this knowledge, try to show or explain how to solve equations without tape diagrams. What actually happened when constructing the tape diagrams? The first set of tape diagrams shows that the quantity of 6 + 2 is equal to 8. To write this algebraically, we can use the equal sign. 6 + 2 = 8.

March 25, 2015 [Day C] In previous lessons, we discussed identity properties. How can we explain why a + 2 - 2 = a using the identity properties? We know that when we add a number and then subtract the same number, the result is the original number. Previously, we demonstrated this identity with a + b - b = a. How can we check our answer? Substitute 6 in for a to determine if the number sentence is true. 6 + 2 = 8 is a true
