Lesson 2 - Comparing Fractions with Unlike Denominators

To encourage students to have fun on the Web while learning about Comparing Fractions with Unlike Denominators, here are some games and interactive activities they can do on their own or in pairs.

Goal

Compare fractions when the denominators are different.

Instructions for Use

Comparing Fractions with Unlike Denominators lets students compare the size of fractions with unlike denominators.

To use Comparing Fractions with Unlike Denominators, click the 'Start' button. Two fractions appear in the text boxes. Click either the 'More Than', 'The Same As' or, the 'Less Than' buttons to make the statement true.

 

Comparing Fractions with Unlike Numerators and Denominators lets students compare the size of fractions with unlike numerators and denominators.

To use Comparing Fractions with Unlike Numerators and Denominators, click the 'Start' button. Two fractions appear in the text boxes. Click either the 'More Than', 'The Same As' or, the 'Less Than' buttons to make the statement true.

 

Comparing Fractions prompts students to solve fraction problems using models and a number line.

To use Comparing Fractions, find the common denominators by clicking the up and down arrow buttons below each graphic to change the number of sections it is divided into. When there are no black lines in the middle of the graphic (only yellow lines), the new denominator divides the original fraction with no remainder.

Change the number of parts that each graphic is divided into until they are equal, and there are no black lines in the graphics.

When the common denominator is found, click in the boxes to the right of the equals signs ( = ) and use the keyboard to enter the equivalent fractions. Click the ' Check ' button. If the answer is correct, a number line will be displayed. If the answer is incorrect, a message will display the error.

After the equivalent fractions are identified, a number line appears. Click on the number line points that represent the equivalent fractions. If the answer is correct, a dot will be displayed on the number line. If the answer is incorrect, a hint will be displayed.

When the equivalent fractions on the number line are identified, enter a fraction that is between the two fractions marked. Use the up and down arrow buttons to the right of the number line to change the number of divisions on the number line. Then, enter the fraction in the boxes above, and click the 'Check' button. A message will display if answer is correct or not.

Click the 'New Fractions' button below the workspace to begin a new problem.
