#### Parent Mathing Tip #9: Shapes

These tips give parents ideas for math exercises that will develop their child's math abilities. Today’s parent tip for “mathing” with your child focuses on shapes.

Welcome to Mathnasium’s Math Tricks series. Today we are finding the value of the *what* part, in a Wholes and Parts problem.

In a Wholes and Parts problem, sometimes we have the *whole* and the *given part*, and we need to find the *what* part. When we are asked, “What part of a bigger number is a smaller number?” it is the same as being asked, “What fraction of the bigger number is the smaller number?” — this gives us the *what* part. Note that here, “is” means “equals.”

To find the value of the *what* part, we use the following steps:

- Identify the whole and the given part.
- Compare the given part to the whole as a fraction in lowest terms.

Follow the examples below to find the *what* part.

**Step 1: Identify the whole and the given part.**

The whole is 54.

The given part is 9.

**Step 2: Compare the given part to the whole as a fraction in lowest terms.**

**Step 1: Identify the whole and the given part.**

The whole is 30 (9 chocolates + 14 gumballs + 7 mints).

The given part is 9 chocolates.

**Step 2: Compare the given part to the whole as a fraction in lowest terms.**
