Core curriculum has definitely changed math curriculum everywhere. At first, I had planned to just ignore it, but since Sola chose Time4Learning for her curriculum, that is not really an option. Honestly, I don’t really mind it. Several international friends have told me that is how they do math in the rest of the world, so I hate to think of us Americans possibly missing out on something good, just because we refuse to try something new. Today, however, Sola was really struggling with a lesson about making tens to solve addition problems.
We finally just made some tens frames mats of our own to help Sola solve her problems and I wish I had done this weeks ago, as her tears just dried right up. It is so much easier to use tens frames to teach how to make tens to solve addition problems! And as I wasn’t easily able to find tens frames mats online, I thought I’d share these tens frames mats that I made for others to use.
For those of you who are not familiar with core curriculum and/or making tens, this is how it works. The idea is that when dealing with certain types of addition problems, it is easier to add in groups of ten. Take the problem 8 + 7 = . You can turn either 7 or 8 into a 10 into a ten, but for my example, we’re going to turn the 8 into a 10.
To turn the 8 into a 10, you need to take 2 away from 7.
You then are left with 1 complete set of 10 and 5 extras. In other words, 15! Which is the correct answer to 8 + 7, yay!
Here is another example. You need to add 7 + 9. You take 1 from the 7 to make the 9 a 10.
Then you have one complete set of 10, plus 6 left over. Which is 16, which is the answer to 9 + 7! Yay again!
Are you using core curriculum math? Do you love it or hate it? Does anyone, but me, feel neutral about it?
