Materials needed: * Whiteboard with markers * Pictures of objects (10-20 different objects such as cats, dogs, apples, etc.)

Procedure: 1. Ask your students, “Can anyone tell me what addition is?” Allow the children to provide their own answers.

1. Draw two columns of boxes on the whiteboard. Label one column “First Set” and the other “Second Set”. Show the students the pictures of objects and ask them to help put the pictures into the two columns.

2. After all the pictures are in the two columns, explain that in addition we are combining two numbers to make a bigger number.

3. Ask the students, “What do you think the answer would be for adding the first set of pictures and the second set of pictures?” (The answer is the total number of objects from both sets combined.)

4. Write the answer both in words and in numbers on the whiteboard beneath the two columns. For example, if the first set had 10 objects and the second set had 5 objects, then your answer would be “Fifteen (15).”

5. Ask the students to come up with other picture problems and add them to the whiteboard. Discuss the answers with the students.

6. Ask the students review questions such as, “What did we do when we practiced addition?” and “What is another word for adding two numbers?”

7. Wrap up the lesson by asking the students to explain what they learned about addition.
