This is a lesson for 3rd grade math about the concept of a fraction. Students color parts to illustrate fractions, write fractions from visual models and from number lines, and learn to draw pie models for some common fractions. Lastly they divide shapes into equal parts themselves and show the given fraction. A whole is divided into two equal parts. ONE part is one half.

Welcome to the world of fractions. Using objects like a pizza, a watermelon and fraction models, understand that a fraction is a few parts out of a whole. Use real world objects like pizza and watermelon, and fraction models to represent simple fractions. Use pictures to identify equivalent fractions. Two equivalent fraction belong to the same whole and have the same size! Use pictures to understand relative size of fractions and practice comparing fractions with same denominators. Use pictures to understand relative size of fractions and practice comparing fractions with same numerators.

A fraction in which numerator is less than denominator is called proper fraction, means a fraction that is less than 1. A fraction in which numerator is greator than or equal to denominator is called proper fraction, means a fraction that is greator than or equal to 1. The whole number is the quotient which is 1. The numerator of the mixed number is the remainder which is 1. The denominator remains to be 3. The whole number is the quotient which is 2.

What would happen if we did not have shapes such as circles and rectangles to refer to? Look at example 4 below. The numerator and the denominator of a fraction must be multiplied by the same nonzero whole number in order to have equivalent fractions. You may be wondering why this is so. In the last lesson, we learned that a fraction that has the same numerator and denominator is equal to one. This is shown below.

## Fraction Games

In math we use the Holt MathCourse 1 Book. We spend 1 — 3 days on each objective. Students typically have a warm-up or an introduction activity each day.
