Hi, my name is Marija, and today I'm gonna show you how to use a grid to teach addition properties. So similar to the grids that you find on a lot of the marble notebooks in the back, you can make an addition grid, even though most of those are multiplication. So we can start by having numbers, we'll just make it smaller for today, we'll do one through five. And going vertically, you can make these numbers whatever you want. So I'm gonna start by counting by tens instead of ones, so we'll go 10, 20, 30, and so on and so forth. So now when the children fill in the grid, you're adding instead of multiplying, like on the back of most of those journals. 10 plus one, is 11. 10 plus two is 12. And they go ahead and they fill in their grid. And the reason that I would have tens going down instead of ones is so that the children can see that once they add these 21 and 31 and 41, that when you're counting by tens, they can see the pattern in the number changes that it's just gonna go 11, 21, 31, 41, and they can catch that pattern with the tens. And then also going horizontally they can see that when you add one more to the ten, the sum goes up just one number, and they can go ahead and continue filling this out and they'll get a full grid just like the multiplication tables. So instead of doing the tens vertically, you can also do fives, that way children can catch the pattern of fives. They can see that it will go five, 10, 15, 20, and it will help them be able to multiply by fives as well. So the vertical column can be whatever you want, and I would keep the horizontal column one through 10.
