Times Tables

I am not sure where I found this but it gives some ways to remember some of the Times Tables

Zero and One Times Tables : Could This Get Any Easier?


Check this out: if you multiply ANYTHING by zero, the answer is zero. Anything. 4 x 0 = 0 and 1,000,000 x 0 = 0. One times tables are almost as easy. Any number multiplied by one is always itself. "Huh," you say? Well, check it out: 1 x 10 = 10, 1 x 42 = 42, 8,726 x 1 = 8,726. Simple, right?

Two Times Tables : Double Your Pleasure

When you multiply a number by two, you just double that number. That's some pretty simple math, even for the most numerically challenged of us. So, if you want to figure out what 2 x 7 is, you just add 7 + 7 (the answer is 14, by the way). Any number times two is the same as that number PLUS itself. Here's one more example: 2 x 5 is the same as 5 + 5, which equals 10. Practice a couple -- it's really easy

Four Times Tables : Double, Double Trouble


OK, so now that you have the twos figured out, it's time to get doubling again. This is not as confusing as it may sound. When you multiply four with anything, you have to use the doubling-up trick (that's the one you used for the two times table) twice. Here's an example: 4 x 7 is the same as 7 + 7 = 14 and then 14 + 14 = 28. So 4 x 7 = 28. Here's another double, double example: 4 x 10 is the same as 10 + 10 = 20, so then 20 + 20 = 40. So the answer is 4 x 10 = 40.

Five Times Tables : It's Why You Have Fingers

First things first - can you count to five? Yeah? Then you can figure out your five times tables. So, when you want to multiply a number by five you just count up by fives that may times. Let's review how to count by fives: 5, 10, 15, 20, 25... and so on. Got it? So if you want to multiply 5 x 7, you just count by fives, seven times. 5, 10, 15, 20, 25, 30, 35. So 7 x 5 = 35. If you have trouble keeping track, just use you fingers.

Hope these help some of your students.
