Multiplication is probably the hardest, yet most important math that elementary students need to know. It is also the most overlooked. Multiplication can be fun and easy. This is the absolute best way to introduce and learn multiplication facts. By using this as a matching game or by using a dry erase marker, this will prove to be the easiest way. My now 4th grader did a full workbook of multiplication amongst many other things and he still only mastered his facts half way. My 2nd grader is just now starting multiplication and is loving this idea. He is working on one number set at a time and is doing awesome with it. Our brain memorizes pictures and we learn best with hands on activities. This combines both essentials to help master multiplication. I am really excited about these flash cards as it will save our family and many others a lot of frustration from happening with memorizing multiplication facts. I can not stress enough how important it is for children to master multiplication as it is the foundation of all later math that will be learned. Be sure to set you paper settings to landscape when you print these, if it doesn't automatically do so. Please leave feedback if you find success with this product. Thank you!
