Objectives Covered:
NC.4.OA.4: Find all factor pairs for whole numbers up to and including 50 to:
• 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
NC.4.OA.1 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.
NC.4.MD.3: 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 a fixed perimeter and varying areas.
