Session 3 — Charts for the Grocer — Turkey
Today's math workshop begins with a warm-up minilesson on multiplication, using a string of related problems designed to encourage the use of the ratio table and facilitate automatizing the multiplication tables. Students then begin an investigation — using the ratio table — to produce charts the grocer can display to help customers as they shop. Today students will work on a chart for turkey; on subsequent days they'll work on charts for carrots, apples, and potatoes. The numbers on the charts have been carefully chosen to support students in moving away from repeated addition strategies toward more efficient grouping strategies.
- Work on a string of related problems designed to encourage students to use facts they know in order to figure out more difficult problems.
- Record student strategies on a t-chart.
- Explain that students will develop charts that list the prices of turkeys of various sizes.
- Do the first two problems in Appendix C as a whole group and then have students work with partners to complete the chart.
- Encourage students to think about how the numbers in the chart might be helpful as they work.
- Plan to focus the congress on the development of more efficient strategies.
- Fill in Appendix C as students share and discuss their strategies.

Next session's materials haven't been added yet.
This session supports development of big ideas, strategies, and models on the Landscape of Learning. Growth toward the standards below comes from sustained, monitored development of those same landscape items across many sessions all year, not from this session, or even this unit, alone.
