I know as a teacher and mother that to perceive the text of a textbook is not always easy for modern children. As practice shows, even strong students do not immediately understand in what situation and how to calculate interest. But I know how to help. I developed a comic book in which pictures and infographics correspond to the clip thinking of modern children. Here are the real situations in the store, on the example of which each child will be able to understand what percentages are and why they should be studied!
Here are eight A4 pages in pdf with funny comics about the cat, which will help children of grades 5-6 to learn the topic of Interest.

The comic answers questions:
1. What is the percentage?
2. How to convert percent to decimal?
3. How to convert decimal to percent?
4. How to find a few percent of the number?
5. How to find a number if a few percent of it is known?
6. How to evaluate, a lot or a little is the percentage of spending?
7. How much is one number from another in percentage?
