Learning goals: Teacher Facing Apply dividing by fractions to calculate the side length of a rectangle, given its area and the other side length. Coordinate (orally) diagrams and equations that represent the area of a rectangle with fractional side lengths. Draw and label a diagram to justify the area of a rectangle with fractional side lengths. Full lesson plan (warm-up, activities, synthesis, cool-down prompt) from 6.4 Dividing Fractions, Grade 6.
