This two-digit addition and subtraction enrichment project can be used to push your higher-level thinkers into a real-world application. Though I used it for grade 2 enrichment, it could easily be used for third grade as well.
In this project, students are put into the shoes of "Sally Savings" where they will use two-digit addition to calculate the amount of money Sally has saved to go on a shopping spree. They will then use subtraction to determine the amount of change Sally has left after shopping at each store.
The product also includes space for students to show their work, as well as questions for students to answer about their calculations and Sally's spending. A common core aligned teacher rubric is included to assess student work following the Common Core Standards. A student reflection rubric and survey are also included to give you feedback about your students' experience with the project. This can be used as a classroom enrichment project, small group project, or even homework based on your students.
