Outcomes

9.C2.1

Use coding to demonstrate an understanding of algebraic concepts including variables, parameters, equations, and inequalities.

9.C2.2

Create code by decomposing situations into computational steps in order to represent mathematical concepts and relationships, and to solve problems.

9.C2.3

Read code to predict its outcome, and alter code to adjust constraints, parameters, and outcomes to represent a similar or new mathematical situation.
