Make Math Work: Money - Cashier Preparing Indigenous Students for Apprenticeship and Employment by Miranda Miller and Robert Horton is one of the titles in Ningwakwe's new series, Make Math Work. On many First Nations across Canada there are various small businesses such as gas stations, variety stores, and restaurants. Each of these stores require customer service cashiers or store clerks. Math skills and money handling are key to the small businesses. This 28-page book in the series focuses on one area of math and numeracy as it relates to a particular job or career. This title begins by introducing an Ojibwe example of traditional knowledge relating to trade and partnerships including pre-contact trading and after contact trade such as the fur trade. A key component of being a cashier is making change. The employee must be able to identify currency, make change, and rounding off cents. Inventory and pricing are two other areas of knowledge. The final section for an employee to master are taxes and discounts. In this area converting percentages to decimals, applying discounts, and tax exemptions are practices the cashier must demonstrate accuracy.
