Standards

HSA-SSE.A.1

Interpret expressions that represent a quantity in terms of its context.*

HSA-APR.D.7

(+) Understand that rational expressions form a system analogous to the rational numbers, closed under addition, subtraction, multiplication, and division by a nonzero rational expression; add, subtract, multiply, and divide rational expressions.

HSA-CED.A.1

Create equations and inequalities in one variable and use them to solve problems. Include equations arising from linear and quadratic functions, and simple rational and exponential functions.

MP3

Construct viable arguments and critique the reasoning of others.

Warm up and Homework Review

10 minutes

I include Warm ups with a Rubric as part of my daily routine. My goal is to allow students to work on Math Practice 3 each day. Grouping students into homogeneous pairs provides an opportunity for appropriately differentiated math conversations. This lesson’s Warm Up- Rational Functions Review Day 2, asks students to evaluate a new method to solve complex fractions and compare it to their current method.

I also use this time to correct and record the previous day's homework.

Review Activity

40 minutes

This activity is inspired by the pass the paper activity that I’ve done in other review lessons. Each slide on the website has two problems. Students will work with their partner and each will simplify or solve one of the problems. If they did their math correctly, they should get the same answer. This will cut down on my having to show them solutions on the board. If they get something different, they will have to analyze their work to find the mistake (Math Practice 3).
