First Addition Lessons

Middlest loves math. She loves counting and numbers and, believe it or not, addition! And after all the drilling she overheard with Oldest last year, she’s a lap or two ahead in this race.

So, knowing how much she loves everything math, I pulled a few of the flashcards that are no issue for Oldest and gave them to Middlest. We’ve been playing some fun games, too.

K4 math

We LOVE counting bears. On the first day, I had her count out the number of bears from her flashcard, and we worked through the combination using the side of the flashcard that showed the answer. On day two, we did the same activity, but I had her work through the combination without the answer.

Then, we pulled out the chalk board and her Fisher Price duplo blocks (similar to legos).  She linked the right number together, we’d read through her flashcard, then we’d write it on the board.

This picture says it all! She is extremely hands-on, so it really is no wonder that she loves math. And I love that addition is coming so easily for her.

Cuisenaire Lessons

I saved our cuisenaire rods until the baby came. I wanted to save them so that I’d have a fun, novel new school lesson for them when school got to be a little more difficult for me. These have been the perfect “new baby” homeschool tool.

I was able to pick up my set from a homeschool consignment store, so I didn’t pay anywhere near what the set would have been brand new. And as I counted all the pieces in the store to be sure they were all there, I could hardly keep their hands out of it. When I pulled it out for the first time a few weeks ago, they were thrilled to finally get to touch and play in them.

Lesson 1

For the first few times, I just let them play. They made people and forts and a myriad of other things, playing in the rods much as they would in a pile of blocks or legos. My goal was to allow them to get familiar with them, to notice that there were 10 different ones, to notice that each was a different size, but all within the context of play.

Then, I had them build staircases, placing the rods side-by-side from smallest to largest. We have continued to do this each time I bring them out. It’s a visual reminder of how many there are and the size relationships. We say the colors up and down the staircase; we say the numbers up and down the staircase.

Last, we play “the magic game.” My oldest absolutely loves this game. I have them hide 3 or 4 different colors behind their backs. It has worked much better to allow them to place the rods on their chairs behind them, since sometimes it’s hard for them to hold them all. In the first round of our game, I ask for a color, and the magic is that they make that color “appear” without looking at the rods; they have to feel the rods and remember which colors are which. In the second round, I ask for the number, and they present the color that corresponds with that number. Each time we play, I add one more rod to our game, which means that we are only on the yellow #5 rod right now. It’s a gradual process, and we build on their success which is why the game is such a hit.

Lesson 2

We are just starting to go a little deeper, beyond just getting familiar. I’m starting to introduce some of the relationship concepts with Oldest, while middle-est is still grasping numbers and colors and sizes. I printed off some 1 cm graph paper specifically for c-rods. Middle-est measured each rod against the paper and colored in that many squares with the matching color. For instance, the black rod equals 7 squares, so she colored those seven squares with her black crayon.

Oldest was assigned the brown rod corresponding to 8, the addition family we are learning right now. He colored 8 squares brown, to match his rod. Then, he found two different rods that equaled 8 and colored in those rods. It illustrated the math facts that he has been learning and was just another fun way to reiterate and reinforce the information. Plus, who wouldn’t like to color their math facts!

light green+yellow=brown, or 3+5=8

I would say that this is not a wonder product. There has been no “a-hah” moment for us, but I do love the variety that it gives us, and I anticipate them being very helpful as we enter more complicated math. Besides, my kinesthetic middle-est is absolutely made for this kind of thing.

Homemade Abacus

My son has been struggling a little bit (okay, a lot) with math lately, and specifically with before and after. So, I put together this rather quaint number line/abacus out of what I had around the house. It’s not much to look at, but it works great! And we’ve had a lot of fun counting our numbers, practicing before and after, and even doing a little addition.

I took an old wire hanger, some mini clothes pins, and a black ink pen for the project. Numbers 1-35 fit nicely on the wire with plenty of room to move them back and forth, and that will keep us plenty busy for awhile, I’m sure.

He did really well using the numbered side for before and after; however, he had a much harder time doing addition. The written numbers threw him off. For addition, I turned the hanger around to the blank side of the clothes pins.

Also, another trick for the addition families that is working so much better. Rather than memorizing them by 1+ or 2+ families as most teach them, we’ve reverted to the A Beka method of teaching the families by the sum:

One Family

0+1=1

1+0=1

Two Family

0+2=2

1+1=2

2+0=2

Three Family

0+3=3

1+2=3

2+1=3

3+1=3

And you get the idea from there. Math keeps me on my toes. I’m constantly on the search for something to help my son with math. So if anyone else has any stunning ideas, I am very open to them. Please feel welcome to comment or email me with your words of wisdom.
