Fraction × & ÷
Understand fraction × integer and fraction division: multiplying an integer means adding that many copies — numerator × integer, denominator unchanged; dividing by a number equals multiplying by its reciprocal.
The Circle
Meet the center, radius and diameter of a circle; discover π by rolling a circle, then derive the circumference and area formulas.
Negative Numbers
Meet negative numbers through a thermometer and a number line: above and below zero, positive and negative — and why 0 is neither.
Expressions & Equations
Meet variables with a mystery box and evaluate expressions by substitution, then solve one-step equations on a balance by doing the same thing to both sides.
Intro to Statistics
Understand the mean, median, and mode, and learn to build and read dot plots of real data
