A lesson plan for grades 3–5 Mathematics
After using an interactive Web site to find patterns in the multiplication tables, the students practice multiplication facts and record their current level of mastery of the multiplication facts on their personal multiplication chart. Illuminations provides resources for completing this activity.
Students will:
- Describe patterns in multiplication.
- Explain the results of multiplying by 0 and by 1.
- Continue filling in a multiplication chart.
- Practice reciting selected multiplication facts.
NCTM Standards and Expectations covered in this lesson include:
- Understanding the effects of multiplying and dividing whole numbers.
- Understanding various meanings of multiplication and division.
- Developing fluency in adding, subtracting, multiplying, and dividing whole numbers.
