Activating Prior review basic Emphasize “keep, problems involving Quick practice: simplify
Knowledge multiplication of fractions change, flip” rule. fractions or time. Combine two work
and simplifying. Review formulas for rates

Understand how to Learn to divide rational Connect real-life Extend skills to multi- Assess understanding
Lesson multiply rational algebraic algebraic expressions situations to rational person or multi-step and reinforce
Purpose/Intention expressions using rules of using reciprocals. expressions and apply rational problems. connections to real-life
fractions and factoring. solving techniques. math.
Vocabulary: multiply, Vocabulary: reciprocal, Vocabulary: work rate, Frame: “The work rate Frame: “This is a
rational, factor, simplify, divisor, numerator, distance, speed, is 1/time, so together, multiplication/division/
reciprocal denominator reciprocal the work rate is real-life problem
Lesson Language Sentence Frame: “To Frame: “To divide, I Frame: “If time = ______.” because ______.”
Practice multiply rational keep the first fraction, distance ÷ rate, then
expressions, I multiply the change division to rate is ______.”
______ and ______, then multiplication, and
simplify.” ______ the second.”
