Time Frame: Approximately 2 weeks

Brief Summary of Unit (Including curricular context and unit goals):
The purpose of this unit is to briefly review multiple-digit addition and subtraction with decimals. The unit starts by reviewing addition with whole numbers, adding decimals, than reviewing subtraction with whole numbers, and then decimals. The unit finishes with a brief finance lesson in how to write checks, receipts, and balance a checkbook. The culminating project is a bazaar where students buy and sell homemade products and keep track of the money they spend by keeping a checkbook in addition to the receipts and checks they have received.
This unit’s instruction is primarily through flipped instruction; the students listen and take notes to a video at home, and then practice the application at school. Flipped videos are accessible through the weebly link at the bottom of the unit. These lessons can also be taught in class.
There are a few important notes to be made about the lesson. The first is that this lesson is designed for students with learning differences and therefore the lesson may be applicable to mainstream students at a younger age or a small group pull out. In addition, this lesson was designed for a small class or a small group pull out. The logistics of the culminating bazaar will have to be adjusted for a large class.

ESTABLISHED GOALS (6.1.A) The student uses mathematical processes to acquire and demonstrate mathematical understanding. The student is expected to apply mathematics to problems arising in everyday life, society, and the workplace.
(6.3.D) Number and operations. The student applies mathematical process standards to represent addition, subtraction, multiplication, and division while solving problems and justifying solutions. The student is expected to: add, subtract, multiply, and divide integers fluently.

Stage 2 – Evidence
Assessment Evidence
PERFORMANCE TASK(S): Students will buy and sell homemade items at a class bazaar using checks, as well as balance a checkbook.

Each student will come to school with pre-priced goods that they will sell to the class (there must be enough for everyone in the class to receive at least one). In addition, students will each be given a checkbook.

Round 1:

In the first round of purchasing/selling the first group students will go to booths that they would like and purchase goods. Students who are buying goods must give a check to the sellers as well as keep track of their expenditures on their checkbooks. The seller will also keep track of income made on their checkbooks and provide a receipt for each purchase made.

Students will return to their desk and must calculate their new net worth and make sure that it matches the amount of money that they have in their checks and receipts.

Round 2-6:

The process will repeat so that every student has a chance to purchase goods from every other student.

Students must make a final tabulation of the amount of money they have at the end of the transactions and compare it to their checks and receipts.

As a final check, students will put their final balances on the board and the class will find the sum, which should equal the total number of students multiplied by \$20. OTHER EVIDENCE:

Entry/Exit Tickets
Stage 3 – Learning Plan
Obj: Students will be able to demonstrate prior knowledge of addition and subtraction as well as financial formatting

Code (A,M,T)

Pre-assessment: Students will complete a brief pre-test with addition and subtraction

problems as well as a word problem asking the students to balance a checkbook.
