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.
