Learning your 12 times tables aka what is 12 times 7?

    Growing up, I learned my times tables through 12x.

    @Torchwood: I definitely had them memorized in 2nd grade (multiplication and division). I have distinct memories of doing timed math tests in Mrs. Kennel's class!

    um, my mind is blown from all these math cheats. I feel like I would've done so much better in math when i was in school! ... I am in finance now though... so go figure.

    Math fluency is just as important as reading fluency. We memorize math facts the same way we memorize "sight words". We want kids to see 5x7 and automatically know the answer without having to figure it out so that their brain doesn't have to do so much processing when they are doing harder math. For kids who aren't fluent, doing middle school or higher math is like trying to read without any automatic word recall. Imagine what it would be like if you had to stop and sound out every single word you read. You could probably do it, but it would be frustrating and inefficient. I am all for teaching the why in math, but fluency is extremely important and that means lots of practice and memorization.

    We learned through 12. I still have all mine memorized but my 12s are a little rusty. DH doesn't really remember any of his times tables.
