Product Description
This activity uses the CERC format (Claim, evidence, reasoning, conclusion) to solve a problem that involves a basic entry level systems of equation problem. A leadership class wants to order t-shirts to sell and they don't know which company to hire. I like the struggle with this assignment because my students always ask "How many shirts are they going to need?" I always tell them that I don't know...which is the point. I want students to figure out the intersection of the two equations so they can give the leadership class advice "If you order less than _____ shirts, hire _____ company, if you order more than ____ hire _____ company. I also encourage students to represent their answer in three forms - table, graph and equation. This problem brings real world application to life and the CERC format allows students to make their thinking visible.
