Looking for patterns
http://illuminations.nctm.org/LessonDetail.aspx?ID=L324
A lesson plan for grades 3–5 Mathematics
Students skip count and examine multiplication patterns, while exploring commutativity in this lesson. Illuminations provides charts, a handout, and songs for skip counting multiplication tables. By asking students a series of guiding questions, the teacher models how to use a number chart to learn multiplication tables.
NCTM Standards and Expectations covered in this lesson include:
- Recognizing equivalent representations for the same number and generating them by decomposing and composing numbers.
- Understanding various meanings of multiplication and division.
- Identifying and using relationships between operations, such as division as the inverse of multiplication, to solve problems.
