Classwork: Today was about proportionality in tables and equations. We started by analyzing two XY tables, In the first table, if you multiplied all of the x values by two, you got the y values. The second table did not have a pattern at all between the x and the y values. We used this concept to connect to constant of proportionality, or the number the multiplies one variable to get the other. We talked about how constants of proportionality and unit rate are related to each other. Student increased their familiarity with the concept through examples, including student created examples. We began work on Problem 2.3 Part A.
