  3. 3Powers, Zero and Negative Exponents, Scientific Notation
  4. 4The Exponent Laws

Integers and fractions with signs, reading imperial measurements, the four operations with positive and negative fractions, and the ratios, rates, proportions and percentages behind prices, maps and taxes.

Coding with Python

Use Python to store values in variables, evaluate formulas, build tables of values and patterns with loops, and test inequalities with conditionals, then read code and change it to model new situations.

  3. 3Conditionals, Inequalities and Altering Code

Tell linear and non-linear relations apart, describe a linear relation by its rate of change and initial value, write y = mx + b from a graph, table or story, compare two relations, and graph special lines, regions and transformed lines.
