Letâ€™s practice 3 and 6 times tables with this mental math worksheet. The dog with big eyes is spying on how well you are training multiplication.

You will get 2 sets of 21 math problems. For the first set of problems, you will have to write the product, and for the second set of problems, you will have to write the unknown factor.

There is also a hidden image that makes learning fun and interesting.

When you write down the correct answer, a piece of the hidden image will appear. You can correct any wrong answer several times.

An important advantage of using the game in school is that the teacher gets immediate information on how well the students are solving multiplication problems, based on the image they discover.
