She starts by putting 10 stickers in each bag, and over the course of a week she adds several bundles of ten stickers to each bag, as well as making more bags. Second graders must find the number of stickers Pia has in total at the end of each day as they read and solve five sequential word problems.

Instructional Ideas

• Give the task as an assessment of the Common Core math standard 2.NBT.A.1a which focuses on tens and bundles of tens
• Use the task as guided instruction and have pairs work together to solve each step, and then come back as a whole-class setting to discuss their answers and demonstrate their methods of solving

Classroom Considerations

• Provide paper for individuals to workout each question 
• Expects that individuals know how many days are in a week

Pros

• Allows young mathematicians to choose their method for solving
• Word problems use a combination of word and numeric formats
• Provides a teacher guide of the task that can be used as a lesson or answer key

Cons

• None
