Thanks to its partnership with publisher Eye on Education, EducationWorld is pleased to present this lesson idea from Family Math Night: Middle School Math Standards in Action, by Jennifer Taylor-Cox and Christine Oberdorf. The activity aligns with the Common Core State Standards for Mathematics, which call upon students to "make sense of problems and persevere in solving them," "reason abstractly and quantitatively" and "look for and make use of structure." This activity requires students to complete multiple operations in order to determine the best salary option.
Materials:
Calculators
Salary option cards
Scissors
Helpful Hints:
The salary option cards include a workspace that students can use to complete calculations. Recording all calculations on these cards allows participants to readily compare each of the pay options. Have many copies of the salary option cards available for students.

Directions:
Cut out the four salary option cards. Shuffle and distribute cards to family members.
Predict and record in your math journal which option would be most lucrative for you during a six-hour day. Verify your prediction by displaying your calculations in a table. You may write on the cards.
Determine if the same pay is still the best if you work an eight-hour day.
