Simple Addition

Today I decided to introduce a little more formal addition to Selena. She basically understands the concept through her counting that when she has more then one item she can count to see how many there are, but to really see the equation was a totally new concept for her.

These were my supplies:



Then I took a piece of white poster board and a black marker.

Selena first was introduced to the plus and equal signs. We started out with the simple 1 + 1 = 2 and went up from there. I put the cubes where they belonged on the addition side, Selena then had to tell me how many total there were and put that many behind the equal sign. As she did this I wrote the equations on the poster board.

We then took our poster board, and using the same skills we just worked on, Selena had to  make each math equation using the cubes.




I felt that this went very well, for her first attempt at some simple math. I am going to use a larger piece of poster board and make a math chart for her with the equations, well as many as I can fit on it, then we can practice this weekly and see how far she gets. We will also use this new found skill in practical life as well.

  1. Great way to immediately math sentences to manipulatives. We kind of dropped the ball on more formal math at the moment - quite simply we don't have time for it with all the other things that we are doing. I am hoping that she will pick it up through play, since we add quite a lot while playing. We also play addition games in the car from time to time, but she doesn't like it much - since it requires too much effort :)

  2. Looks like a great introduction! Sammy started doing some "addition" the other day. He had 1 balloon and asked for another so he could have 2. Since he "added" I figured why not :-P. However he was on to me. He said I have 2 want 1 more. So have 3 :-P

  3. Wow! That's awesome that you are teaching early math. Learning the basic concept is the key:)

    God Bless

  4. How very cool! I remember when I was teaching we created a picture book when we got to the doubles. I'll have to see if I can track it down for whenever you get there.
    I just need to get back to working on our math. Some days it's two steps forward and one back.
