Finding products
http://illuminations.nctm.org/LessonDetail.aspx?ID=L528
A lesson plan for grade 3 Mathematics
Students continue to examine the role of commutativity and the multiplicative identity, play a multiplication game, and explore products where one of the factors is 6. Using resources provided by Illuminations, students practice their multiplication tables and eventually work up to their 6 tables.
Students will:
- Find products where one factor is 6.
- Use the commutative property.
- Explore the results of multiplying by 1 and by 0.
- Practice the multiplication facts with factors of 6.
NCTM Standards and Expectations covered in this lesson include:
- Understanding the effects of multiplying and dividing whole numbers.
- Developing fluency with basic number combinations for multiplication and division and use these combinations to mentally compute related problems, such as 3050.
- Selecting appropriate methods and tools for computing with whole numbers from among mental computation, estimation, calculators, and paper and pencil according to the context and nature of the computation and use the selected method or tools.
