Non-Random Variables: NBA Championship
Learners demonstrate probability distribution of non-random variables. Students collect data on the NBA Championships. They record the data and compute subsets and permutations.
Curated OER
2 x 2 Linear Systems
Learners graph 2x2 systems and solve them algebraically. They investigate parallel systems by solving equations.
Curated OER
Variables
Students watch a video show how to identify the independent variable, dependent variable and controls in an experiment; and design experiments that use controls to isolate a single independent variable and measure the resulting dependent...
