• Marie is sending 5 paperback books to her cousin.
  Each book weighs 4 ounces. She is mailing them in
  a box that weighs 6 ounces. The total package
  must weigh less than 26 ounces. Will she be
  allowed to send the package? Why or why not?

Johns pet snake weighs 15 pounds (lbs) more than
Toms pet dog. The total weight of both animals
is 145 pounds. A) Tom says the equation d
15 145 can be used to find the weight of Toms
dog. Explain whether or not Tom is correct.B)
Find the weight of Johns pet snake in pounds.

CRA Day 6 Rubric

• Mathematical Content
• 7.RP.2 Student recognizes that Toms equation is
  incorrect. Can explain using the fact the snake
  is 15lbs MORE than the dog, that the snake is not
  just 15lbs, or that the equation does not
  represent the snake the dog.

13
CRA Day 6 Rubric

• Mathematical Practice
• MP1 The student correctly identifies Toms
  equation as incorrect correctly finds the weight
  of the snake as 80lbs.
• MP3 The student explains how Toms equation is
  incorrect, or correctly solves for the weight of
  the snake as 80lbs.
• MP6 The student provides accurate labels and
  units as needed and includes carefully formulated
  explanations about the equation.

CRA Review Day 7

• A) Translate the following word problem into an
  algebraic expression about the cashier's current
  hourly wage A cashier at the corner grocery was
  earning 6.25 an hour.  He received a raise of 25
  cents an hour. Use h for the number of hours.
• B) The cashier earned 39 for working 6 hours.
  Was this before or after the 25 cent per hour
  raise? Justify your answer in words.
• C) What would the cashier earn at his new wage if
  he worked 8 hours on each day Monday-Friday?  Use
  your expression from part A to show your work.

  accurate expression and explains all values used.
• 7.EE.4 The student uses the variable h
  appropriately and indicates proper usage in Part
  C.

16
CRA Day 7 Rubric

• Mathematical Practice
• MP1 The student correctly creates and explains
  the algebraic expression (a) identifies the 39
  as after the raise and offers reasonable
  explanation (b) solves for 260 using the
  expression (c)
• MP6 The student uses appropriate units in all
  answers and explains the meaning of all constants
  and variables
• MP7 The student solved part C with their correct
  expression from part A

  ratios given below
• In 2011, the Tennessee Titans had a record of
  nine wins and seven losses. In 2012, the Titans
  had six wins and ten losses.
• What is the ratio of wins to games played in
  2012?
• What is the ratio of wins in 2011 to wins in 2012?

The girls soccer team is baking cupcakes for a
bake sale. Sally started baking first, but
together she and Tina made 5 dozen cupcakes.A.
The graph and equation shown represent the
girls combined dozens of cupcakes. Explain
what the 2 and 1 represent in the context of
the story.B. Explain how to use the equation to
find how long it would take the girls to bake 8
dozen cupcakes. Then find the number of hours.

• CRA Review Day 8

CRA Day 8 Rubric

• Mathematical Content
• 7.RP.2b The student identifies the 2 as the
  dozens baked per hour and the 1 as the dozen
  Sally already baked before Tina joined
• 7.EE.4 The student correctly uses the 8 hours as
  the y in the equation and solves for 3.5 hours
  for x

20
CRA Rubric Day 8

• Mathematical Practice
• MP1 The student explains the 2 is the dozens
  baked per hour, the 1 is the dozen Sally made in
  advance explains that the 8 is the y value and
  solves for 3.5 hours
• MP3 The students explanations are accurate and
  their algebra is sound
• MP6 The students label the 1 2 correctly and
  replace the 8 correctly to solve
