Standards & Objectives

Essential and guiding questions: 

PART A:

  • Tell me the first thing you wrote on your paper. What is important to remember when expressing ratios? (MP6)
  • How are the ratios you wrote for part A related? What patterns did you see? (MP7)

PART B:
Equivalent Ratios in a Table

  • I know some people made a table to solve part B. How did this help? (MP8)
  • What is the relationship between the steps given in the problem and the answer you gave? (MP7)
  • Looking at your table, how could you scale up the 5 and the 4 to answer the question more efficiently? (MP2, MP7)
  • If 5 x 13 = 65 and 4 x 13 = 52, how is the 13 related to the 117? (MP7)
  • If Casey walked 130 steps, how could you quickly determine how many steps Jasmine took? (MP8)

Scaling the Whole

  • Some of you divided 117 by 9. How did you know to divide by 9? What did this tell you? (MP1, MP2, MP7)
  • How are the 117 and 9 related? (MP7)
  • Who can show how this method connects to using the table? (MP3)

Activity/Task Variations

Blooms taxonomy level: 
Understanding
Differentiation suggestions: 

If students can’t get started….
Assessing:

  • Tell me what you are trying to do for part A. For part B? (MP1, MP2)

Advancing:

  • If Jasmine walks 8 steps, how many would Casey walk? How many did they walk together? How could you use the relationship to figure out part B? (MP2, MP7)
Extension suggestions: 

If students finish early….
Assessing

  • What is the ratio for the number of steps you found for part B? (7)

Advancing

  • What is the relationship between the ratios you found in part A and the number of steps you found in part B? (MP7, MP8)
