Lesson Objective
Lesson Plan
Element/Time 
Teacher 
Do Now (8:30 – 8:40)/(10:00 –10:10) 
· Teacher walks around to greet students and check in with students about their do now and homework 
HW Check 
· Teacher walks around to help/spot check student HW 
Mental Math (8:40 – 8:50) /(10:10 – 10:20) 
· Teacher reads and reveals a series of 6 problems – helping students to think of strategies to help students solve the problems · Teacher pulls sticks (cold call) to have students answer the questions 
Mini Lesson (8:50 – 9:25)/(10:20 – 10:55) 
Intro: · Today we are going to look just expressions. Who can remind me what an expression is? (cold call) expressions are mathematical phrases – they don’t have equal signs · Sometimes expressions are written so that they have lots of different terms. · We are able to combine any terms that are similar or “like” · A like term is when a term has the same variable attached to it. · Demonstrate visually a expression with many terms (use hands on equations materials – putting the like with like (white pieces with white pieces and blues with blues) · We can put together terms that are the same – demonstrate with materials. · Let’s see what we did with mathematical symbols. · Focus students that when combining the like terms you are just adding the coefficients together – example 2x + 3x combines to 5x · Walk through several examples of subtracting to combine like terms – what happens when there is a subtraction sign – it means we are taking away some of the terms. Guided: · Have students use materials to model an expression. · Then explain to students that they can put together any thing that is the same. · Ask students to show what was done with symbols.
Independent: · Complete worksheet Closing: · What did we learn? · Like terms can be combined together · Why is important? · What are some common mistakes? What does successful work look like/sound like?
