Activity Objective The student will model addition situations involving fractions with objects, pictures, words, and numbers.

Materials Have Cake and Eat It, Too Rectangular sheet of paper Colored pencils

Facilitation Questions How can you fold the paper so that you have four equal parts?

Answers may vary. Possible answers: I could fold the paper in half two times. When I unfold the paper, the folds divide the paper into four equal parts. I could shade one of

those parts to represent 1

4.

How could you use the same sheet of paper to model eighths? Answers may vary. Possible answer: I could fold the paper in half twice in the same way that I folded it before, and then I could fold it one more time. When I unfold the paper, the folds now divide the paper into eight equal parts. I could shade three of those parts

to represent 3

8.

How do the additional folds change the representation of 1

4?

Answers may vary. Possible answer: The additional folds divide the part of the paper

that represents 1

4 into two equal parts. I could name the part

2

8 because

2

8 is

equivalent to 1

4.

Answers

Sketch of your paper model

Portion of cake eaten by Ted

Use words to describe your solution. Five out of eight parts of the paper are

shaded, so Harvey and Ted ate 5

8 of

the cake.

Have Cake and Eat It, Too

Harvey made a cake to share with his friend Ted. Harvey ate 1

4 of the cake, and Ted ate

3

8 of

the cake. 1. Use one sheet of paper. Fold the paper into fourths and then shade the paper to represent

the portion of the cake that Harvey ate. 2. Fold the same sheet of paper into eighths. Using a different color, shade the paper to

represent the portion of the cake that Ted ate. 3. Use the shaded portions on the sheet of paper to determine the portion of the cake Harvey

and Ted ate altogether. Sketch of your paper model

Use words to describe your solution. Use numbers to represent the problem situation and your solution.

Communicating About Mathematics How does the paper model verify the solution to the problem situation?

Activity Objective The student will represent ratios and percents with concrete models, fractions, and decimals.

Materials Fractions and Percents Color Tiles

Facilitation Questions Does the total number of tiles in the set represent the numerator or denominator

of a fraction? Why? Answers may vary. Possible answers: The total number of tiles in the set would be the denominator of a fraction because it represents the entire set.

Does the number of blue tiles in the set represent the numerator or denominator of a fraction? Why? Answers may vary. Possible answers: The total number of blue tiles in the set would be the numerator of a fraction because it represents a part of the entire set.

If you divided 100 into 4 equal parts, what would be the value of each equal part? Answers may vary. Possible answer: 100 4 25 , so each part would have a value equal to 25%.

If the blue tiles represent 3 of the 4 equal parts and 1 part is equal to 25%, how could you use multiplication to determine the percentage of tiles in the set that are blue? Answers may vary. Possible answer: If one part is equal to 25%, then I could multiply 3 25 75 to determine that the blue tiles are 75% of the entire set.

Activity Objective The student will use multiplication and division of whole numbers to solve problems including situations involving equivalent ratios and rates.

Materials Measurement Equivalences Measurement Equivalence Cards Tape or glue Scissors

Facilitation Questions How could you generate an equivalent ratio?

Answers may vary. Possible answers: I could multiply or divide the numerator and denominator by the same number to create a ratio equivalent to a given ratio.

What is the relationship between inches to feet in .48 in

4 ft?

Answers may vary. Possible answers: The relationship is 12 inches to every 1 foot.

How could you use this relationship to find an equivalent ratio? Answers may vary. Possible answer: I could look for other ratios that have a relationship of 12 inches to every 1 foot.
