Part-Part-Whole
- Group: Whole Class
- Materials: Part-Part-Whole sheet, paper and pencil
Explain that students will use a bar diagram and number bonds to organize the information in word problems to identify the part-part-whole. Explain that students will be finding either a part or whole in a problem. Write the problem below on the board. Help students identify the parts and whole in the problem and which one they are trying to find.
Sally put some pictures in a book. Only 13 of them were good. She gave 5 of them to friends. How many pictures does she have left?

Distribute the Part-Part-Whole sheet to each student. Guide students through some of the problems to help them determine where in each diagram to write the numbers. Use part-whole language as each problem is reviewed. Have students write appropriate number sentences to match the diagrams. After an allotted time, invite three volunteers at a time to model how they displayed the problems using bar diagrams, number bonds, and number sentences.
