Study Sheet: Unit 2 Math - North Carolina Content State Standards

  1. Multiplicative Comparisons: - Interpret a multiplication equation as a comparison. - Multiply or divide to solve word problems involving multiplicative comparisons using models and equations with a symbol for the unknown number. - Distinguish multiplicative comparison from additive comparison.

  2. Two-Step Word Problems: - Solve two-step word problems involving the four operations with whole numbers. - Use estimation strategies to assess reasonableness of answers. - Interpret remainders in word problems. - Represent problems using equations with a letter standing for unknown quantity.

  3. Factors and Multiples: - Find all factor pairs for whole numbers up to and including 50. - Recognize that a whole number is a multiple of each of its factors. - Determine whether a given whole number is a multiple of a given one-digit number. - Determine if the number is prime or composite.

  4. Area and Perimeter: - Solve problems with area and perimeter. - Find areas of rectilinear figures with known side lengths. - Solve problems involving a fixed area and varying perimeters, and with a fixed perimeter and varying areas. - Apply the area and perimeter formulas for rectangles in real-world and mathematical problems.
