Expressions and Equations 8.EE7. Solve linear
equations in one variable.
CCSS More Math
CCSS Other (Math, Listening and Speaking)
2. Solve linear equations with rational number
Analyze and solve linear equations and pairs of coefficients, including equations whose solutions
simultaneous linear equations.
require expanding expressions using the distributive
property and collecting like terms.
1. Give examples of linear equations in one
variable with one solution, infinitely many
solutions, or no solutions. Show which of these
possibilities is the case by successively
transforming the given equation into simpler
forms, until an equivalent equation of the
form x = a, a = a, or a = b results (where a and
b are different numbers).
Essential Questions:
Students will keep considering…

revised, meant to provoke
thought in students,

DO NOW: 1) Take out your Do Now papers 2) Simplify this expression: -4y2 + 5y + 12 – 2y -6y2 – 2 ***Use the 4 steps
from yesterday to separate the terms, color “code” them, Group them together, simplify
LEARNING TARGET: 8.EE.7b
I can identify like terms
I can rewrite expressions into a simplified form by combining like terms
I can explain the essential understandings about combining like terms.
AGENDA:
Review 3 essential understandings: (Students will fill in blanks for these and glue into booklets from previous day)
1. Only like terms can be combined.
2. Always put variables in alphabetical order, then order by exponent
3. Always move the operator signs with the terms.
Practice combining like terms- use learning activity(Partners)
1. The teacher will demonstrate color coding the strip, cutting it apart, and reordering using the Commutative property, and
simplifying the expression
2. Students will practice with one of their strips – Partners will check the color coding and re-ordering before pieces are glued
Then students will write the simplified expression to the side
3.Students continue the activity with their partners
**Do the first 1-4 together, with modeling and guided practice Final 6 students will do on their own
Practice combining like terms with Puzzle from “teachers.Henricho.k12.va.us”
ASSIGNMENT: Finish 6 practice problems on your own,
