Equality and Inequality (Lesson Plan)

January 21-23, 2009

WEDNESDAY
1.21.2009

Standard 6PRA1 Use the properties of equality to solve problems using letter name variables (eg ¼ + x = 7/12)

WARM UP:

Give the definition:
-Concepts
-Problems
-variables
- equality-inequality

Goal(s)/ Expectation(s)

The student will:
T1 GOAL: Distinguish between variables and numbers in an equation.
T2 GOAL: Solve an equation with a letter name variable as the solution (eg, 4+1=x)
T3 GOAL: Solve an equation with a letter name variable in a position other than the solution (eg, 9+x=10)
By answering at least 4/5 math problems on the board and on paper.

ESSENTIAL QUESTION:
How do we solve problems of inequality using letter name variables?

WHOLE GROUP INSTRUCTION:
Show this PowerPoint presentation on Linear Equations: http://jc-schools.net/PPT/linear-equations.ppt

SMALL GROUP INSTRUCTION: Break the students in three groups and give them 5 math problems involving linear equations. Ask them to:

T1 GOAL: Distinguish between variables and numbers in an equation.
T2 GOAL: Solve an equation with a letter name variable as the solution (eg, 4+1=x)
T3 GOAL: Solve an equation with a letter name variable in a position other than the solution (eg, 9+x=10)

Standard(s) 6PRA1 Use the properties of equality to solve problems using letter name variables
(eg ¼ + x = 7/12)

WARM UP:
7+9=x
8-x=10
x-6=18
7+3=x
8-x=12

Goal(s)/ Expectation(s)

The student will:
T1 GOAL: Distinguish between variables and numbers in an equation.
T2 GOAL: Solve an equation with a letter name variable as the solution (eg, 4+1=x)
T3 GOAL: Solve an equation with a letter name variable in a position other than the solution (eg, 9+x=10)
By answering at least 4/5 math problems on the board and on paper.

FRIDAY
1.23.2009

Standard(s) 6PRA4 Simplify expressions of the first degree by combining like terms and using specific values.

WARM UP:
3x+ x = 12
6+ 4 = y
12x + y = 3x -2y

Goal(s)/ Expectation(s)

The student will:
T1 GOAL: Distinguish between an equation and an expression.
T2 GOAL: Label a problem as equal or unequal
T3 GOAL: Match two equations that are equal
By solving linear problems on the Promethean Board.

ESSENTIAL QUESTION:
How do we know which are like terms?
