2. Content-
|
| Algebra, Variable, Balanced, Equation, Expression, unknown, Constant |
| |
|
3. Goals: Aims/Outcomes-
|
1.Be able to use the properties of addition, multiplication, and/or
division in written and mental computations.
2.Be able to find the missing term(s) in a pattern using pictures
and numbers.
3. Represent mathematical situations and structures using algebraic
representations
|
| |
|
|
4. Objectives-
|
1.Create a model of an equation using manipulatives
2.Translate a pictorial representation into an equation.
3.Evaluate equation involving basic operations by substitution (Guess
and Check) |
| |
|
5. Materials and Aids-
|
| balance scale mat, cubes, pawns, teacher model set, digital projector,
individual whiteboards (marker & eraser), student note sheet, worksheet |
| |
|
6. Procedures/Methods-
|
|
A. Introduction-
1.Review the purpose of the scale mat and pieces by name, pawn =
x (unknown quantity), cube = constant (number that stays the same)
2.At the end of this lesson-should be able to use the manipulative
to create an equation, draw a picture of the mat to represent the
equation and use Guess & Check to solve for x.

|
|
B. Development-
1. Write 2x on whiteboard.
2. Show students what that looks like with teacher materials. Discuss
the 2 in front of the x. Compare that to the cube 2. Make sure students
know the difference by adding a +2 on the whiteboard. Then adding
a cube 2 on teacher model. Ask if it is an equation or an expression.
(Think Pair/Share w/ reasoning of difference)
3. Create an equation with class using their suggestions and teacher
set.
4.(After step 1 in practice), Show students how to draw picture of
the balance mat. ( = pawn, =cube) |

|
|
C. Practice-
1.Write "2x + x = x + 8" on whiteboard. Have students create on
their mats. Check for understanding by circulating.
2. Have students draw the picture of their mats on the whiteboards.
Check for understanding.
3. Students copy the equation on whiteboard and use Guess & Check
to solve for x on whiteboard. Check for understanding.
4. Try another equation. 3x + 1 = x + 7. |
| |
|
|
D. Independent Practice-
1. Distribute worksheet. Have students fold into 4ths.
2. On back, have students draw the equations. On front, use Guess
& Check to solve for x. Show work. Discuss #5-10. This is review from
Lesson 1.

E. Accommodations (Differentiated Instruction)-
1.Call small group of students that had/may have problems with lesson.
(Teacher observation during check for understanding & knowledge of
individuals)
2.Bring mat, bag of materials, whiteboard, and worksheet with pencil.
3. Go over #1 & #2 together using whiteboards then pencil on worksheet. |

F. Checking for understanding-
1.Discuss what was learned this lesson.
2. What was difficult and how they figured out what to do. What was
easy.

G. Closure-
1.Record new learning on notes page.
2. Quick thumbs up/down for "Got It" |
