In these concepts, you will be introduced to the basic concepts of algebra and will practice your problem solving skills. There are five concepts, and each one focuses on a key algebraic thinking strategy. You will focus on describing, solving, and checking your thinking.
In these concepts we first learned to compare quantities and weights with picture graphs and teeter-totters. We learned to use patterns to figure out missing information with train cars. We also used proportional reasoning with packing bags. Last, we learned how to use clues and deductive reasoning to match pictures.
