More on Math and Multiplication

Math bingo is a fun method of reviewing times tables.

All you need is bingo cards that have numbers on them (the numbers of course being the correct answers to the times table you're working on), then call out the calculations that make up those number.

For example, let's say you're working on your 9 times table. You call out 9 times 7; your kids need to figure out the answer and see if that number (63) is on their card.

Having trouble with the 9 times? Use the 9-method!

Let's say you want to see how much 9X7 is.

Just hold out all 10 fingers, and lower the 7th finger. There are 6 fingers to the left and 3 fingers on the right.

The answer is 63!

Go ahead: practice building your speed with Underwater Times Tables, at a great site called What2Learn.com.

Okay, now who can tell me what 8 X 9 is? Come on!

Math homework, anyone?

Oh, boy! Grade 5/6 math homework has reared its head, and I'm as baffled as my kids!

Some resources I've found, used and liked include:

• This interactive multiplication table. Once you enter the equation, you not only get the answer (yay!) but you also see both paths of numbers light up -- ie., 6 X 9 will also "remind" you that 9 X 6 gives you the same answer.

• A page of definitions all about fractions *shudder* Not only do you learn what the term means, you also find out how to get the answer. For instance, when you get to the bit about Converting and Reducing Fractions, the text reads:

For any fraction, multiplying the numerator and denominator by the same nonzero number gives an equivalent fraction. We can convert one fraction to an equivalent fraction by using this method.

and then gives numeric examples like this: 1/2 = (1 × 3)/(2 × 3) = 3/6

• At MathPlayground.com, there's a game where you convert mixed numbers to improper fractions (but it shows you how, first of course!).

• If you're trying to simplify fractions, there's a good page at a site called MathIsFun.com. First, simplifying is explained and a few methods on how to do it are shown. There's a tool you can use to quickly (and automatically) simplify fractions -- an explanation on how the answer is reached is offered with the answer.

More to come, I'm sure. And, please -- if you've found a helpful site, let us all know by leaving a comment.

Thanks!
