The Lemonade ProblemLemonade costs 88¢ for one 64 oz. bottle. At the Lady Texans Basketball Game, Marcie sold cups holding 8 ounces for 50¢ and cups holding 16 ounces for 75¢. What is the fewest number of cups of each she needs to sell to make at least $50?

Problem Solving Block

1. What is the product of the 6th multiple of four and the 3rd multiple of seven?

2. What is the quotient of 352 divided by 2? (Use a T Chart to Solve)

3. Janet recorded the number of cakes she baked this week? Then she subtracted 7 and multiplied the difference by 10. The result was 80. What is the number of cakes she baked this week?

4. The chart below shows how many markers come in a package.

If the pattern continued, how many markers would be in 15 packages?

5. Write the following number in standard form: Seventy-three thousand, two hundred six

6. David went to the feed store with $200. He purchased six bails of hay for $12 each, 4 bags of oats for $18 each and a bag of dog food for $20. How much money did he have left?

Congruent Shapes and Symmetry

Congruent

Show video 15-4 on www.pearsonsuccess.net

You have learned that figures related by translations, rotations and reflections are the same size and shape. Today, you will learn to use these relationships to test if two figures are the same size and shape.

Using your tangram pieces, find the following pairs:

A congruent pair-same size and shapeA pair with different sizes but the same shapeA pair with different size and shape.

Congruent FiguresHow can we use translations, rotations and reflections to prove

figures are congruent?

Congruent pairs are the same size and shape. What pairs did you find?

Why are the figures in each of these pairs congruent?

Which pairs of pieces did you find that are not congruent?

Why aren’t these figures in these pairs congruent?

Congruent FiguresHow can we use translations, rotations and reflections to prove

figures are congruent?

Symmetry

Show video 15-5 on www.pearsonsuccess.net

You have just learned that figures related by reflection are the same size and shape, so how can we use this relationship to identify symmetry?

Give each student a piece of construction paper. Fold and cut into a snow flake to demonstrate symmetry.

Line of SymmetryHow can we use reflections to verify that a shape has

symmetry?

What is a line of symmetry?

What does it mean for a shape to be symmetrical?

• Symmetrical means it can be folded on a line to form two congruent halves that fit on top of each other.

• A line of symmetry is the fold line that separates the congruent sides.

• A figure can have many lines of symmetry.

• A figure can have no line of symmetry too.

How can we make a design symmetrical? Today you’ll be making two symmetrical designs with your partner, and if you have time, one design that is not symmetrical.

1. Draw your line of symmetry.

2. Select your first polygon.

3. If we are going to make a symmetrical design, what block should we put on the other side of line, and where should we put it?

4. Repeat with additional shapes…

5. Create two shapes with your partner.

Discussion: Symmetry

Share designs.

If we say something has symmetry, what do we mean?

We know all of our designs have at least one line of symmetry. Do any of them have more than one line of symmetry?
