Equivalent fraction models

The  exercise appears under the 3rd Grade Math Mission. This exercise uses various models to help better understand equivalent fractions.

Types of Problems
There are two types of problems in this exercise:


 * 1) Select how many pieces to shade the same: This problem provides a figure that has a certain fraction shaded. A picture follows with the same shape cut into different denominations. The student is asked to type in how many regions should be shaded to make the same amount.Efm1-1.png
 * 2) Select all that shade the asked amount: This problem provides a diagram of a whole, and a given amount that is to be shaded. The student is asked to select all the options from below that shade the required amount.Efm1-2.png

Strategies
Knowledge of how to make common denominators would assist on this exercise, but a keen eye is all that is needed to get the answer in most cases.
 * 1) On the first problem type, the picture is labeled well so it is possible to count the number of regions one needs to make the same amount.

Real-life applications

 * 1) Creating equivalent fractions is a useful tool for being able to do some of the operations on fractions, such as addition and subtraction.
