Videos, worksheets, games and activities to help Grade 3 students understand fractions.
This lesson will help you develop an understanding of division by:
• explaining that a fraction represents a part of a whole
• comparing fractions of the same whole that have like denominators
A fraction can be used to name a part of a whole.
For example, the following circle is divided into four equal parts: blue, green, yellow and red. Each part, or color, of the circle represents 1/4 (one-fourth) of the whole circle. 4/4 or 1 represents the whole circle.
You use numerators and denominators to name fractions. The numerator (top number) of the fraction tells the number of parts being considered. The denominator (bottom number) of the fraction tells the number of parts.
If two fractions have the same denominator, the fraction with the greater numerator represents the larger piece of the whole. If the denominators of two fractions from the same whole are the same, then the parts are the same.
We can use the symbols for greater than and less than (< and >) when comparing fractions with the same denominator.
If John ate 2/6 of the pizza and Gina ate 3/6 of the pizza, who ate the most pizza?
