The first race
http://illuminations.nctm.org/LessonDetail.aspx?ID=L590
A lesson plan for grades 3–4 Mathematics
Using the E-Example simulation, students will model multiplication facts on the number line and compare various representations. Illuminations provides all activity sheets necessary for completing the lesson. Using an online simulation program, students predict which runner will be farther along by multiplying strides by distance traveled.
Students will:
- Compare representations of multiplication on the number line.
- Find the product of two factors 0-9.
NCTM Standards and Expectation covered in this lesson include:
- Describe, extend, and make generalizations about geometric and numeric patterns.
- Represent and analyze patterns and functions, using words, tables, and graphs.
- Model problem situations with objects and use representations such as graphs, tables, and equations to draw conclusions.
