Everyday we use addition and subtraction. This educational lesson will help you learn addition and subtraction in our classroom. It will also help you learn key words on how to add and subtract. Pictures on the addition and subtraction column allow you to visualize subtraction and addition, and the numerical problems will allow you to practice your math skills.
Task
In classroom groups you will use paper columns with addition and subtraction problems on them to better understand mathematical concepts.
1. Identify the key words and symbols that tell you to add or subtract.
2. We will use the image attached to learn addition and subtraction.
3. In your groups you will learn how to use the column to answer the basic math questions.
Process
I will print the image on the teacher's page so that each of you will have your own addition and subtraction column.
Fold the table so that you create a rectangular cube.
Tape the top and bottom of the sheet of paper.
I will hand out the addition and subtraction columns as an education tool.
You will use the columns to answer the following questions:
If you had two lemons and took one away, how many would you have?
If you bought one apple and found two more, how many would you have?
What number is 4 more than 5?
What number is 3 less than 6?
Extra credit: If I had 1 lemon, and bought 3 more, but then lost 1, how many would I have?
Evaluation
I will use the following rubric to evaluate the students' work on The Webquest for problem solving.

Conclusion
Math can be less intimidating when students associate addition and subtraction with items they know and can visually see the result. Once they get their basic addition and subtraction down, numerical problems on the column will help them hone their math skills.
