Lesson
Grade 3
General
In this lesson, students will learn the steps (using division) to calculate simple fractions as part of a whole.

Standards
CCSS.MATH.CONTENT.3.NF.A.1

Learning objective
Students will be able to calculate simple fractions as part of a whole.

Introduction
Students will look at pictures and decide what fraction they see. Knowing how to find fractions will help students know how many objects you get if you are given the fraction.

Instruction
A fraction has a numerator and denominator. A character will model the steps to calculate fractions with a sample problem: find the fraction of the whole you want to know and divide the total by the denominator. Students will then practice this skill by calculating one-third of a group of marbles. They will do a few other problems using simple division to calculate one-half and one-fifth. They will also do word problems.

Quiz
Students will complete 10 fill-in-the-blank and short answer questions.

Closing
The lesson closes with 3 more practice problems.
