Last updated about 3 years ago

10 Nsɛmmisa

Today's Learning Goal:

Interpret the structure of a multi-step linear equation to plan and justify a solution process by identifying the order in which a sequence of operations needs to be un-done using inverse operations.

Reminders:

Inverse operations undo each other. Some inverse operations include addition/subtraction, multiplication/division, squaring/square rooting.

Today's Materials:

Laptop
Note Sheet
Pencil
Binder

Please complete the Jump Start #3-4 (activator). This is independent it should be silent.

Mini Lesson: Launch, Explore, and Discuss

Introducing Elvira, a cafeteria worker at a school. Lets take a look at the guided notes sheet.

Does it matter which order the notes were recorded in?

Determine how many students were originally sitting at the front table based on the sequence of notes that appears in each ordering.

First order of Elvira's notes:
BACKWARDS Model, Create equation, and undo to check.

Second order of Elvira's notes:
BACKWARDS Model, Create equation, and undo to check.

Third order of Elvira's notes:
Create equation, solve it, and check.

Explain why it matters the order you put your operations. How and why does it affect the solution?

Independent Practice

#5-8

Solve the equations and check your solution.

Independent Practice

#9-10

Indicate whether the given value is a solution to the equation. Show your work to justify your response.
