Introduction/applications:

“GIMMIE! GIMMIE ! GIMMIE ! is what you’ll be saying when you visit the GIMMIE School Store !” This is the store that helps you answer the questions:

Question:

“How can I buy things that I want?” “How much change will I get in return?”

Model:

Money and school supplies labeled with varied prices

Resources and Materials (estimated cost): $20.00

Poster board, money (real or plastic), school supply items, containers, worksheets and pencils, calculators

Procedures and Activities: After teaching subtracting across zeroes:

1. Review concepts of shopping, buying items, receiving change.

2. Introduce the school supply store by discussing items and prices, and that students will be “given” a $5.00 bill to spend at the store.

3. Complete an example together: Use two teacher chosen items, add their costs, then subtract the total from $5.00 to find the change the students would receive from the clerk. Have students check their work using calculators.

4. Repeat step 3, but use a student choice for each of the 2 items.

5. Repeat steps 3 and 4, but use 3 items from the store each time.

6. Distribute worksheets. Allow students to work in pairs to complete the sheet. Have students check their work with calculators.

Answers/Rubric

Each person will check their partner’s answers with a calculator. Students will help partners correct any errors. However, if these or similar worksheets are to be corrected by the teacher, the following rubric would be used:

4 points- The student completed the task with no errors in spelling, prices matching store items, computation, or labeling.

3 points- The student completed the task with no errors in spelling, prices matching store items or computation.

2 points- The student completed the task with no addition errors.

1 point- The student completed the task with many errors in spelling, prices

matching store items, computation, or labeling; or the student did not

attempt to complete the task.
