I finally got some addition and subtraction work together that I've been wanting to get on the shelves all year!! Nothing like putting it out when there are only 2 weeks left. Anyway......my 2nd year students (and a few 1st years) have really been enjoying this. Below you can see how I've set it up on one of my math shelves. The two baskets on top of my math drawers have addition and subtraction equations in them. The little paper holder has blank record sheets, and you will find out about the green gray and bowls by reading further.

To do this work, the child selects a math manipulative drawer. Each drawer has 10 objects in it. They pull the drawer out and carry it to their table.

They also get the basket of equations, a record sheet, pencil, and the tray with bowls. The work is set up as shown below. The child takes an equation from the basket and places it in the bottom of the tray. The manipulative objects are placed to the left side and the record sheet to the right.

Using the objects, the child places the correct number of objects for each addend into the two blue bowls as shown below.

Next, the child physically pours the contents of the two blue bowls into the green bowl. I love this part of the activity because it really reinforces the ACT of adding........putting two groups together.......in a really tactile way.

Then the child pours the "sum" into the large part of the tray to count it as shown below.

Below you can see the student counting the objects to determine the total quantity.

The last step is to write the equation with the correct answer on the record sheet. For my students who can't form letters very well yet, I get out my number stamps. They are usually able to write the symbols for "+" and "=" on their own.

If you are interested, you can download the record sheet to print. I also wanted to upload the files for the equations but I can't find them anywhere on my computer! Ugh! However, I'll tell you how I did it. I set up the equation cards to be printed on standard size address labels. Then I peeled and stuck them on pink cardstock for addition and blue for subtraction and laminated them.

Thanks for sharing! Another great resource I use for math games is:

It provides a range of math teaching resources, math games, and hands-on math activities for K through 5th grade and all activities are correlated with the Common Core State Standards.

Hi,

Your idea of addition and subtraction seems to be good. This type of idea we can implement to the childrens and they can also understand easily.

Thanks for this article.

The idea you have used to decorate the shelf was very pretty and articles u have added is very nice and looks beautiful to.

Great idea! I'm going to try this with my daughter. I'm also interested in how you modify it for subtraction, as I find it is often harder to do physically than addition.

What a great way to learn math... brings magic into learning.

LOVE THIS and can't wait to implement it~*THANK YOU!* and WHY haven't *I* thought of this before? DOH! (((((HUGS))))) sandi

Great idea! However I'm curious how to explain using this for subtraction. Pouring the two first bowls into the third and final bowl then counting them all together is a visual for the addition. How do you physically explain doing the subtraction version of this activity?

I love this! I teach special ed. (mostly learning disabilities) 1/2 day and this is a great way to reinforce addition and subtraction. I also love your blog, as I am a preschool teacher the other half of the day. Thank you thank you!

hello, thank you for this great idea, (excuse my poor english, i'm french).

This is super, thanks! I set out a similar work for my girl and she's totally into it. Do you have a way to adapt it to subtraction? Taking things from the first bowl, putting them into the second, and then dumping bowl one into bowl three to count? Does that sound right? So far we're just adding, but subtracting could be fun too, yes?

What a great idea. I love how the child picks which manipulative to use. I'm keeping this one for the future.

This is an excellent way to show addition. I really like it. I want to adapt a work I was making, haven't put it out, just felt it wasn't quite right, now I know how to fix it. Thanks so much!

This is so great! I will definitely put this work together for my daughter.
