Learning Objective

I can identify fractions of shapes like 1/2, 1/3, 1/4.

Today's Lesson

Today we will learn how to identify fractions of shapes like 1/2, 1/3, 1/4. Math helps us solve problems and understand the world around us.

A fraction represents part of a whole. The top number (numerator) tells us how many parts we have. The bottom number (denominator) tells us how many equal parts make the whole. For example, 1/2 means we have 1 part out of 2 equal parts—that's one half. If you cut a pizza into 4 equal slices and take 1 slice, you have 1/4 of the pizza.

Let's break this down step by step so it's easy to understand. Follow along with the examples, and don't worry if it takes some practice to get the hang of it!

Remember: Making mistakes is part of learning. If something is tricky, try again, look at the examples, or ask for help.
