Modeling and One Step Equations with Algebra Tiles

Solve for x

• x = 4

• x = 1

• 2x = 4

• x = 2

What equation is modeled? Solve the equation.

• x -6 = 13

• x + 6 = 13

• x + 6 = 13

• x - 6 = 13

Write the equation for the model. (white square=1 rectangle=x red square = -1)

• 7=x+3

• 7=x+(-3)

• 7=-x+3

• -7=x-3

Which equation matches the image? THE RECTANGLES ARE THE VARIABLES & THE SQUARES EQUAL ONE EACH.

• x - 3 = 8

• x + 3 = 8

• 3x = 8

• 3x = 9

Solve the equation using the image. THE RECTANGLES ARE THE VARIABLES & THE SQUARES EQUAL ONE EACH.

• n = 14

• n = 6

• n = 7

• n = 2

If the triangle represents the variable and each circle equals one, is this model and equation in the image correct?

• Yes

• No, there needs to be 7 circles on the right side of the equal sign.

• No, there needs to be 4 circles on the right side of the equal sign.

• No, there needs to be a minus sign in the equation.

Which equations matches the picture?

• 3B + 1 = 6

• B + 3 = 6

• 1 + 3 = 6

• 6 = 3B + 1

Which equation matches the picture above?

• c = 4

• 1 + 1 = 8

• 2 = 8

• 2C = 8

Write an equation for the model above.

• x + 3 = -9
• x - 3 = 9
• 3x + 1 = 9
• 3x - 1 = 9

What equation is modeled?

• 3 = 6
