Here is another fun, quick and easy way to practice fact fluency this summer. This example uses match box cars, but you could use ANYTHING that you have.
First, choose a set number of cars. I would start with 5. Line up the cars near a "garage." In this case, we just use a shoe box. If our child wants to decorate a box to make it look like a real garage, that is great. It is always a good idea to make this fun and creative.
Ask your child, "How many cars do you have?"
He or she will tell you, "Five!"
Now, ask your child to turn around or cover his or her eyes. Place some of the cars in the garage.
You can both see that there are three cars outside of the garage. The question you want your child to be able to answer is, "If we started with 5 cars, and now there are 3 cars, how many cars must be in the garage?"
As they become more and more proficient, use larger sets of items.
