What students need to be able to do

  • Estimate and identify the two consecutive natural numbers between which the positive square root of a given number lies (1 to 400) and justify the better approximation.
  • Use rational approximations (to the nearest hundredth) of irrational numbers to compare, order, and locate values on a number line.
  • Compare and order up to five real numbers (integers, fractions, decimals, mixed numbers, percents, scientific notation, radicals, π) using benchmarks, number lines, or equivalency.
  • Justify solutions for comparing and ordering real numbers orally, in writing, or with a model.
