Teacher Carol Barnes Pre-Algebra 8th Q1W9 Oct. 11-15 Focus 4 Solving Multi-Step Equations
Standard(s) Taught

MAFS.8.EE.3.7

Solve linear equations in one variable.

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).

2. Solve linear equations with rational number coefficients, including equations whose solutions require expanding expressions using the distributive property and collecting like terms.

Learning Targets and Learning Criteria

a.

• solve a linear equation with one solution, no solution, and infinitely many solutions.

• explain when an equation has one solution, no solution, and infinitely many solutions.

b.

• simplify equations using distributive property, combining like terms, and inverse operations.

• solve multi-step linear equations with rational number coefficients.

Classroom Activities

Monday:                                                                                                                                                 Bellringer:  Solve one-step equations:  2x = 18;  x/2 = 6;  x – 5 = 15;  x + 4 = 6

Whole Group:   Review the Distributive Property on the board:  2(x +4) = 10;  -4(x – 3) = 14;  -(x – 2) = 4                                                                                                                                     Interactive Student Notebook (ISN) – Page 12 Two-step equations with distributive property and combining like terms on the same side of equations.

Small Groups:  IXL   (7th grade) R.12 Distributive Property,   IXL  Y.8 with a partner to 80%

Independent:   IXL Y.9, Y.11

Wednesday:                                                                                                                                       Bellringer:  Solve equations:  3(x – 2) = 4;  2(x + 5) = 20

Whole Group:  Equations with variables on both sides.  3x + 4 + 2x = 14;  -5x – 3 + 10x = 27;  8 + 2x -4 = 10

Individual:                                                                                                                                      IXLs — Y.12 (80%)
