Answer:

**Unlock the Problem**

Vicki bought an ice cream cake cut into 6 equal pieces. Vicki, Margo, and Elena each took 2 pieces of the cake home. Vicki says she and each of her friends took \(\frac{1}{3}\) of the cake home. Is Vicki correct?

Answer:

• Into how many pieces was the cake cut?

Answer:

• How many pieces did each girl take?

Answer:

**Activity**

Materials: color pencils

STEP 1 Use a blue pencil to shade the pieces Vicki took home.

STEP 2 Use a red pencil to shade the pieces Margo took home.

STEP 3 Use a yellow pencil to shade the pieces Elena took home.

The cake is divided into ________ equal-size pieces. The 3 colors on the model show how to combine sixth-size pieces to make _________ equal third-size pieces.

Answer:

So, Vicki is correct. Vicki, Margo, and Elena each took \(\frac{}{}\) of the cake home.

Answer:

Mathematical Processes

Compare the models for \(\frac{2}{6}\) and \(\frac{1}{3}\). Explain how the sizes the parts are related.

Answer:

**One Way** Use models to write an equivalent fraction in simplest form.

To simplify \(\frac{6}{10}\), you can combine tenth-size parts into equal groups with 2 parts each.

Answer:

**Another Way **use common factors to write \(\frac{6}{10}\) in simplest form.

A fraction is in simplest form when 1 is the only factor that the numerator and denominator have in common. The parts of the whole cannot be combined into fewer equal-size parts to show the same fraction.

So, \(\frac{6}{10}\) written in simplest form is __________
