# Fraction maths

This MagiWise app has been developed for and with children, which get the first education in fractions. The app explains in simple wording and examples the basic theory of calculating with fractions. After doing all exercises the child knows how to add and transform all kind of fractions. Also the app helps in a friendly way to get the understanding of what you can do with fractions. This app contains 10 chapters with many interactive instruction pages, 18 exercises and finally 3 tests.

Like every MagiWise app the structure of the app is made like a school booklet. The idea is to create an educational experience during using the app (instead a solely game experience). The exercises can be executed in different order. After doing the exercises the exercise results can be evaluated. The following subjects are presented in the app:

• Understanding the denominator of the fraction.
• Understanding the numerator of the fraction.
• Adding fractions with similar denominators.
• Learn how to change the denominator without changing the fraction as whole.
• Adding two fractions with different denominators.
• Simplify fractions.

## The exercises

This app contains 10 chapters with different instruction pages alternated with 18 learning exercises and 3 keys. The structure of the app is in the form of a script, so that the exercises can optionally be performed in a different order. The app is ideal to support the preparation of citric keys and connects with Dutch primary school education groups aging 7 up to 12 years old.

### The structure

The following topics are covered in the app:

• The denominator of the fraction.
• The numerator.
• Addition of fractions with equal denominators.
• All fractions.
• Calculating with all fractions.
• Changing the denominator.
• Addition of fractions with unequal denominators.
• Cross Evening fractions with unequal denominators.
• simplify outcome.
• Test the previous topics on three levels.

### The denominator

This chapter explains the function of a fraction itself. What is a fraction? With some examples the app will explain that a fraction consisting of a numerator and a denominator, then the app is focusing to the denominator. After the explanation there are two exercises that is practiced to determine the denominator. In the first exercise, a figure appears where each time one surface is colored. Prompted to select the corresponding fraction and placing it on the mark. In the second exercise shows a fraction and four possible pictures. The question here is to choose the correct image at the fraction. In the two exercises, we focus exclusively on the denominator and not on the numerator. Therefore, only fractions are shown with the counter 1, so the feeling for the denominator can be practiced.

### The numerator

This chapter describes the function of the numerator. What we give to the numerator? A few examples will explain that a fraction may consist of several colored surfaces of an equal number of pieces. Again two exercises that show similarities with the exercises in the previous chapter, but now also trained the numerator next to the denominator. With these two exercises you will practice the basic principle of a fraction. We recommend not to proceed with the next exercises as long as these exercises are not made sufficient. Minimum two stars is recommended.

This chapter starts with calculating with fractions. First, the principle of the sum of two fractions is explained. Then follow two simple exercises that accusations are being asked to solve. The sums include simple fractions in which the denominator are equal. The first exercise in addition to the sum also shows a picture of the sum, so that the student can follow the count. In the second exercise is also shown the picture, however, the student with the finger fill the plates themselves. By correctly filling the fractions in the picture, the student can derive the solution. These two exercises incorporated within every 20 sums that are randomly assembled from a larger amount of sums.

This chapter is explaining and practicing with the fact that a solution may also consist of whole parts and a fraction. E.g. 1 1/2. Through figures, the amounts shown and practiced. Here, too, the first exercise already contains colored examples and the second exercise, the possibility to coloring in the examples. The sums include here only fractions with equal denominators.

### Change denominator

In this chapter, it is practiced with changing the denominator  without that the fraction change itself. For example, 2/4 equals 1/2. After the student can change the denominator and understand the underlying theory, a start can be made with the addition of dissimilar fractions. The first exercise a simple fracture is shown with the colored figure. The student must then choose the picture which shows the same colored part and infer the fracture. In the second exercise the options are not completed and should be completed by the student and then make the right choice. We also recommend here not to proceed as long as the exercises are not completed with two stars.

### Cross-equalization of fractions

This chapter explains the method to create fractions with unequal denominators into two fractions with a different denominator. The student must then cross multiply fractions with the denominator of the other fraction. The downside is that there are major fractures occur, so the method should be used only as a last resort. These two exercises practise this method. After the student has completed this exercise with at least two stars can make the second test.

### Simplifying fractions

The final part is the subject of "simplifying a fraction" explained. If a fraction, for example 12/16, the result is large (large denominator), the student must check whether the numerator and the denominator can be divided with the same number. This chapter explains this and practiced. In these exercises, the student can use the write function on the screen.

### The tests

This app also contains three tests that can be taken in the learning process at any given time. In all three tests the student will see four sums with the correct answers. During the test it will not be displayed if the answers are placed correctly with the right question. Afterwards, the student can request this in the final screen.

MagiWise is developing funny and educational apps for tablets in the classroom and at home on the couch.
