I Am Amazed
Oh. My. Goodness.
Do you know what I witnessed today? I watched my daughter learn her +9 math facts in a matter of about....10 minutes. Now, you might think that I'm exaggerating here, but I am not at all.
Math-U-See teaches that 9 always wants to be 10, so he uses his vacuum hose (the round hole at the top of the 9!) to steal 1 from the number being added to him to make him 10. Therefore, 9+5 becomes 10+4, which is 14....well, that seems a little bit confusing as I write it, but it's less confusing when you're sitting there with the blocks in hand, saying it out loud and looking at the blocks. BUT, I looked at the blocks and said to Reilly, "Hey, here's an even easier way to think about it! You know you're going to make a teen number when you're adding to 9, right? (she nodded her head) Well, just look at the number you're adding, take away 1, and make it a teen!"
Just like that, she had it.
Have I said lately how much I love Math U See?
