## Objectives

- To visualize equivalent fractions.
- To practice with the addition and subtraction of fractions.
- To explore the addition of mixed numbers.

## Materials

- Paper plates
- Scissors
- Crayons or markers
- Green construction paper

## Procedure

- Color in each plate with a different color.
- Divide each plate up into different numbers of equal pieces using a ruler/straightedge and a marker. For example, one plate may be cut into 8 equal parts and another plate might be cut into 4 equal pieces.
- Label each piece of the plate with the fraction of the plate it represents. For example, the pieces of the plate that was divided into 8 equal pieces would each be labeled with a $\frac{1}{8}$18.
- Cut along the lines created with the ruler/straightedge.
- Cut out stems for the flowers from a piece of construction paper (optional: cut out a long rectangle for grass and tape the stems to this rectangle) arrange the stems as shown below:

## Investigate!

Use the pieces of plate to make flowers for each of the stems. One complete flower is a complete circle. How many ways can this be done? Try out as many as you can.

Here’s an example:

##### Questions

- Compare with friends! Did someone else come up with a petal combination you didn't use? Why do you think theirs works too?
- Can you think of any way to express each full flower combination as a sum of mixed numbers?
- What happens if you take away one petal from your flower? What fraction of the flower is left? Does this fraction change if you remove a different petal? Why?
