The Contexts for Learning Mathematics Teacher Pack: Grades 2–3 contains 1 Getting Started guide, 3 unit books, 2 context-setting read-aloud books, and 5 context-setting posters.

 

Ages and Timelines begins with the story of eight-year-old Carlos’s visit with his great-grandfather. Carlos’s fascination with his great-grandfather’s beautiful silver hair, and the time it will take him to grow a similar mane, initiates a family-wide investigation into age differences. The context of age differences and the open number line model support the development of subtraction strategies.

 

Students revisit the Masloppy family in The T-Shirt Factory as Grandma Masloppy launches a lucrative T-shirt business. This context and follow-up simulations highlight place value, regrouping, equivalence, and systematic exchange. As the unit progresses, standard addition and subtraction algorithms are explored, and the concept of place value is developed to four places.

 

Groceries, Stamps, and Measuring Strips uses baker’s trays, patio tiles, and other real-world resources to introduce fundamental multiplication strategies. The careful arrangements of these resources invite repeated addition, skip-counting, and doubling strategies, as well as introduce the language of grouping. Measurement strips are used to explore the relationships between products.
