Built to 8.EE.A.2, 8.NS.A.1, 8.NS.A.2. Each lesson has guided notes, practice, an exit ticket, a homework page, worked answer keys and a click-by-click Teacher Deck.
- Lesson 1 Square & Cube Roots I can evaluate square roots of perfect squares and cube roots of perfect cubes, solve x² = p and x³ = p, and know that the square root of a whole number that is not a perfect square is irrational.
- Lesson 2 Rational vs Irrational Numbers I can tell whether a number is rational or irrational from its decimal expansion or its square root, and write a repeating decimal as a fraction.
- Lesson 3 Repeating Decimals to Fractions I can choose the multiples of a repeating decimal that line up, subtract them, write the decimal as a fraction in simplest form, and check it by dividing.
- Lesson 4 Approximating Irrational Numbers I can find the whole numbers and tenths a square root is between, round it to the nearest tenth, and use rational approximations to compare, order and place irrational numbers.
- Lesson 5 Roots in Context I can find the side of a square from its area and the edge of a cube from its volume, and give the answer left as a root or as a rounded decimal, with units, as the question asks.
