#### 2 Direct Instruction

The teacher will read, If You Were a Plus Sign written by Trisha Speed Shaskan. Following the story, the teacher will review the addition concept introduced in the story. Emphasis will be placed on the plus sign, and the structure of an addition sentence.

Next, as a whole the class will create some addition stories. The teacher will draw each story on chart paper, again placing emphasis on the plus sign, and the addition sentence.

Following the story, the students will rotate through four math centers:

At the first center the students will create and color their own addition story. Students are to use the, If I Were a Plus Sign - Addition Story worksheets.

At the second center the students will play Spill & Add. Each student will shake the plastic cup filled with 5 two-colored counters, and spill them onto the table. Next, the student will record the results by coloring the counters on the, Spill & Add worksheet, and write the number sentence. The student will repeat these steps using the plastic cup filled with 10 two-colored counters.
