I just finished this book – Singapore Math 6B.

It covered:

  • Rate
  • Circle
  • Pie Charts
  • Area and Perimeter
  • Volume
  • Challenging Word Problems
  • Rate = Distance / Time

    Circumference = Π * Diameter

    Area of a Circle = Π * Radius2

    Area of a Semi-Circle = .5 * Π * Radius2

    Area of a Quadrant(of a Circle) = .25 * Π * Radius2

    Volume of a Box = Width * Length * Height

    Volume of a Cube = Side3
