# Videos, games, and books for memorizing addition & subtraction facts

## Videos

The following videos use fact families to help children learn the facts within 0-10 (first grade math). Each video shows all the fact families with the sum of that particular number, organized into a table. Seeing the facts within a pattern, within a structure, helps develop number sense and helps children in the memorization work.

I don't personally like to only use "brute force" memorization techniques such as flash cards, but also include strategies and show the child patterns. (Flash cards are fine as one tool among many, but I wouldn't rely on them as the MAIN means of memorization.)

Each video also includes a drill and other types of exercises and problems.
