MAP 5th Grade Math

A comprehensive course preparing 5th graders for the MAP math assessment, covering essential concepts and real-world math skills.

Basic Concepts

Fractions and Decimals

What Are Fractions?

Fractions show parts of a whole. The top number (numerator) tells how many parts you have, and the bottom number (denominator) tells how many equal parts make up the whole.

\( \frac{3}{4} \) means 3 out of 4 equal parts.

Decimals

Decimals are another way to show parts of a whole, but they use a dot (decimal point).

0.25 is the same as \( \frac{1}{4} \).

Comparing and Converting

You can compare fractions and decimals or even change one to the other.

\( 0.5 = \frac{1}{2} \)

Why It Matters

Fractions and decimals pop up when you’re measuring, handling money, or slicing a pizza!

Examples

  • If you eat 2 slices out of an 8-slice pizza, you've eaten \( \frac{2}{8} = \frac{1}{4} \) of the pizza.

  • Buying a toy for $3.75 means you understand decimals and money.
