Easy Strategies to Learn Multiplication Facts
I was in my middle daughter’s 3rd grade classroom today as the guest reader when I found this gem on the whiteboard. My daughter chose Danny, the Champion of the World by Roald Dahl so I read the first few chapters to the class which has the story of The B.F.G. (Big Friendly Giant) snuck in. The B.F.G. is another book by Roald Dahl that kids seem to consistently rave about and many of the kids in her class had already read it and nodded their heads happily when I asked them if they liked it. I was able to tell them about Roald Dahl Day in England — September 13, his birthday — and her teacher is planning an author study this Spring which will make my daughter very happy because she is chugging along through all his books.
My daughter said that her class came up with a list of strategies to learn multiplication. In fact, her friend Helena came up with the x8 trick. Learning math facts seems to work best when it gets presented different ways; this is the logical reasoning method. The post I refer to throughout on Tips and Tricks uses songs; another great way to go. We do flashcards and mnemonic as well. The only one I know is 8 x 8: I ate and I ate ’til I threw up on the floor, so 8 times 8 is 64! It works so well that my youngest knew 8 x 8 at age 3 but just that one because he finds gross humor particularly funny. If you have any other tricks or tips, please share!
p.s. I have another post here on Tips and Tricks to Master Multiplication and Division Math Facts that uses skip counting songs, and shows the times 9 hand trick.
x 1: it’s just the number itself. 10 x 1 = 10
x 0: it’s always zero. This is the only multiplier that always has the same answer. anything x 0= 0
x 10: just add a zero to the number. 2 x 10 = 20
x 2: double the number. 4 x 2=8 (i.e. 4 + 4= 8)
x 5: count by 5’s. The answer always ends in either 5 or 0. 5 x 5= 25
x 9: hand trick.
x 3: count by 3’s
x 4: double, double
x 8: double double double
for x 6 and x 7, use the skip counting songs.
