It's no secret that children solve addition examples faster than subtraction problems. It is much more difficult for primary school students. To understand the topic of a future lesson, someone parses it in advance. However, this approach leads to a loss of interest.
To help a child understand the principle of the solution itself, you need to teach him the composition of the number at least up to 20. He must understand that, for example, 20 is 16 and 4, 12 and 8, 7 and 13. Some children very quickly understand that to speed up solutions need to remember the triplets of numbers. And the best assistant in this case is the example simulators.
Here is a generator of examples for subtraction within 20. In one lesson, the child will be able to solve many non-repetitive tasks. To save time, you can download the examples instead of rewriting them. After that, parents can check the correctness of the solution by downloading the options with the answers.
You can do it every day. The advantage of our generator is the variety of tasks. Each time the page is reopened, the child will be offered new tasks. This will eliminate the likelihood of memorizing answers and will speed up your subtraction skills. In the future, it will be easier for the student to solve more complex examples for other actions.
