Rocket Launch

A rocket is launched from a cliff. The relationship between the height of the rocket, , and the time since its launch, , in seconds, can be represented by the following function:

  • When does the rocket reach its maximum height? Show work.
  • What is its maximum height? Show work.
  • How long after it reaches its maximum height does the rocket hit the ground? Show work.
  • What does the number 384 mean in terms of this context?

F-IF.4/ Claim 1

 F-IF.7a/ Claim 1

F-IF.7a/ Claim 2A

 F-IF.4? Claim 2C

A 4-point response demonstrates full and complete understanding of the standard and claims by doing all the following:

  • Shows supporting work and writes 2.5 seconds.
  • Shows supporting work and writes 484 feet.
  • Shows supporting work and writes 5.5 seconds.
  • States that 384 represents the height from which the rocket was launched.

A 3-point response demonstrates reasonable understanding of the standard and claims by doing three the following:

  • Shows supporting work and writes 2.5 seconds.
  • Shows supporting work and writes 484 feet.
  • Shows supporting work and writes 5.5 seconds.
  • States that 384 represents the height from which the rocket was launched.

A 2-point response demonstrates partial understanding of the standard and claims by doing two the following:

  • Shows supporting work and writes 2.5 seconds.
  • Shows supporting work and writes 484 feet.
  • Shows supporting work and writes 5.5 seconds.
  • States that 384 represents the height from which the rocket was launched.

A 1-point response demonstrates limited understanding of the standard and claims by doing one of the following:

  • Shows supporting work and writes 2.5 seconds.
  • Shows supporting work and writes 484 feet.
  • Shows supporting work and writes 5.5 seconds.
  • States that 384 represents the height from which the rocket was launched.

A 0-point response demonstrates almost no understanding of the standard and claims.

 

 

OSPI Quadratic Instructional Task Exemplar

OSPI Quadratic Instructional Task G Exemplar

A rocket is launched from a cliff. The relationship between the height of the rocket, , and the time since its launch ,, in seconds, can be represented by the following function:

  • When does the rocket reach its maximum height?
  • What is its maximum height?
  • How long after it reaches its maximum height does the rocket hit the ground?
  • What does the number 384 mean in terms of this context?

 

  •  

The rocket reached its maximum height 2.5 seconds after it was launched.

The rocket’s maximum height was 484 feet.

The rocket hit the ground 8 seconds after launching, or 5.5 seconds after it reached its maximum height.

  • The 384 in the function represents the height from which the rocket was launched.
