Traffic Light L23 R23 9-25-13 Learning Goal: I will… What I already know about expressions.. PROOF OF LEARNING: guided practice Reflection 7.EE.2, 7.EE.3; 7.NS.3 Application Problems with Integers Lesson Objective: Students will be able to write an expression from a verbal situation and solve application problems .
R23 9-25-13 Mathematical Practice: Make sense of problems and persevere in solving them.
R23 9-25-13 How do you solve multi-step problems with rational numbers? Q Identify the question T Think about the problem I Identify important information PSolve the problem by translating the phrases into mathematical expressions. Use order of operations to simplify. S Check your solution.
R23 9-25-13 Write the problem in your notes. Jill and Kelly work as consultants and get paid per project. Jill is paid a project fee of $25 plus $10 per hour. Kelly is paid a project fee of $18 plus $14 per hour. Write an expression to represent how much a company will pay to hire both consultants for a project. Q - What is the problem asking? Write the question in your own words
T- Think about how to solve. Write an expression I - Identify important information. Jill: Fee + Rate per hour $25 + $10h Kelly : Fee + Rate per hour $18 + $14h
Jill + Kelly = cost to hire both consultants $25 + $10h + $18 + $14h = cost $43 + $24h = cost The company will page $43 + $24h for both Jill and Kelly to work on their project. S-Does the solution make sense?
Traffic Light L23 Guided Practice Each week, Joey gets paid $10 plus $2 for each chore he does. His sister Julie get paid $5 plus $3 per chore. a.
