Memorize the Multiplication Tables

This activity is designed to memorize the multiplication tables. Students will learn their facts one by one starting from the easiest ones. Normally kids are able to learn their facts during 1-2 months spending 6-10 hours in all. Daily practice is very important. It is better to practice 15 minutes every day than several hours once a week.

Please note that practicing is different from the memorization. By memorizing, students create multiplication and division skills, by practicing - they master them. When the memorization of the multiplication tables will be finished, start practicing multiplication and division to continue to master the skills.
