Learning Objective

I can find percent of a number using models.

Today's Lesson

Today we will learn how to find percent of a number using models. Math helps us solve problems and understand the world around us.

Percent means "out of 100." The symbol % stands for percent. For example, 50% means 50 out of 100, which is the same as 1/2 or 0.50. To find a percent, divide the part by the whole and multiply by 100. Percents are used everywhere: test scores (80%), discounts (25% off), and statistics (60% of students). Understanding percents helps you compare and understand data!

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.
