The creamery
http://illuminations.nctm.org/LessonDetail.aspx?ID=L521
A lesson plan for Grades 3–5 Mathematics
Students estimate and determine the number of ice cream sundae combinations that can be made with two topping possibilities and a number of ice cream flavors. They write number sentences for the number of combinations that can be made from a given number of possibilities. Using dice, students work in pairs to determine the product of two numbers. Then, students practice application by estimating how many ice cream/topping combinations they can make. This lesson uses helpful graphic organizers and drawing activities. Illuminations provides directions and activity sheets for completing the lesson.
Students will:
- Predict the number of two-variable combinations that can be made.
- Determine the number of combinations that can be made.
- Generalize the number of possible combinations that can be made.
- Write an equation to determine the combinations possible.
NCTM Standards and Expectations:
- Represent data using tables and graphs such as line plots, bar graphs, and line graphs.
- Design investigations to address a question and consider how data-collection methods affect the nature of the data set.
- Collect data using observations, surveys, and experiments.
