What should a 7th grader be able to do after this unit?

Use C = πd and A = πr² to find circumference and area from a radius or diameter, explain how the two formulas relate, solve shaded-region problems, and find unknown angles using complementary, supplementary, adjacent and vertical angle relationships.

How can a student use RepeatWatch for formula practice?

Loop the moment a teacher substitutes the radius into the formula, then slow it to 0.75× to copy each line. Save the circumference and area examples on separate number keys, and use Stop after N loops for a short review.
