The mathematical topics presented included multi-step adding and subtraction , multiplicative reasoning , unit rate , ratio and halving contexts of division . These mathematical topics were addressed while addressing the following financial literacy topics : profit , promotions , market competition , overhead costs , and entrepreneurship .
The class worked together to help students prepare for the trade show . For example , a

The class knew that Parker would need to present his product to students who would select the final vendors for the store . Parker presented the price per rubber band to the class . Using the number of bands presented , the class calculated and discussed the cost to build a variety of designs . With facilitation , the class determined that ($ 0.02 x n ), where n was the number of bands used would generate the cost of materials . Further class discussion generated concerns that the cost should include the $ 10.00 original cost of the loom used to weave the bracelet and generated this equation ($ 0.02 x n ) +$ 10.00 . Fellow students commented that this would indicate a loom was purchased for each bracelet . Parker , however , did not believe the loom should be a part of the costs because he received it as a birthday gift .
