Materials: Cloud addition work mat, several cotton balls, recording sheet (based on group ability level), and pencil (for each child)
Group 1 (High)

Students will be responsible for reading their own story problems. Teacher will provide scaffolding as needed.

Students will use cotton balls to illustrate each problem.

Unneeded information will be inserted into problems, so children have to discriminate which information to use.

This group will be adding two numbers to 20.

After cotton balls have been placed on mat, students will record the problem on their record sheets, writing a full number sentence. Their record sheets will be a blank piece of paper. They will be responsible for every element of the number sentence.

An extension activity for this group is to have them glue three cloud combinations to a blue piece of construction paper. Students will write an addition number sentence for their picture. Ex: 4+5+3=12
Groups 2 and 3 (Middle)

Teacher will recite a variety of addition story problems to the group. Students will use cotton balls to illustrate each problem.

Students will be adding two numbers to 15.

The record sheet will be formatted as follows: ____+_____=______.

The students will have a number line to refer to for number writing. A variety of manipulatives will also be provided.
