Student Achievement Chart (SAC)

Standard(s):
Content: 7.RP.3 – Use proportional relationships to solve multistep ratio and percent problems.
Examples: simple interest, tax, markups, and markdowns, gratuities and commissions, fees,
percent increase and decrease, and percent error.

Literacy (6-12): Craft & Structure – Interpret words and phrases as they are used in a text,
including determining technical, connotative, and figurative meanings, and analyze how
specific word choices shape meaning or tone.

Objective/LT for Pre-assessment:
Leaming Target: I can calculate and interpret percent error, with an accuracy of 3 out of 4 times.
Objectives: Students will be able to …

calculate the actual value when given the percent error by organizing the given information
appropriately with an accuracy of 3 ( out of 4) or better.
calculate the percent error when given the actual value by organizing the given information
appropriately with an accuracy of 3 ( out of 4) or better.
draw conclusions about the percent error, actual value, and accepted value in the context of the
situation by analyzing various real-world applications with an accuracy of 3 ( out of 4) or
better.
