Lesson 9 of 22

## Objective: Students will be able to set up and solve one and two step equations.

**Opener: **As students enter the room, they will immediately pick up and begin working on the opener – Instructional Strategy - Process for openers. This method of working and going over the opener lends itself to allow students to construct viable arguments and critique the reasoning of others, which is **mathematical practice 3**.

**Learning Target: **After completion of the opener, I will address the day’s learning targets to the students. For today's lesson, the intended target is “I can use inverse operations to solve a two step equation.” Students will jot the learning target down in their agendas (our version of a student planner, there is a place to write the learning target for every day).

**Review Game: **One and Two Step Review Explore Narrative This review game pits one half of the room against the other, and when competition is part of the lesson - you better be precise! (**mathematical practice 6**) Students will have to show all steps, explain their reasoning, and be able to answer any question I may pose about their work. Students will not only be solving problems, but they will also be reasoning through word problems (**mathematical practice 2/4**). Students will work in groups, explain their reasoning to one another - and help one another solve problems if there is confusion (**mathematical practice 1/3**). Today, I am simply the facilitator - I do not help! (okay - I do, I can't help myself...but I only help if a group is repeatedly making the same mistake and it is obvious they need assistance!)

#### Summary

*5 min*

**Self-Reflection: **On the back of their opener, I am going to ask that students write me a short reflection regarding the question – in a two step equation, in what order do you undo the operations? This reflection question gives me the opportunity to get an idea of what the students understand and what they do not. If a student cannot put into words that they undo addition or subtraction first, then I know there is an issue.
