Multiplication Facts

Work with your grade level group to find “multiplication facts” in the course of study for your grade level

Learning Progression

Look at the learning progression at your table and find your problem situation in the learning progression.

Discuss your thoughts at your table.

Discuss

What grade should a student be able to solve these problems?

What’s the difference in a strategy and algorithm?

What does mathematical fluency mean?

What questions related to multiplication might you ask your students about this picture?

What does it mean to have multiplicative reasoning?

“Multiplicative reasoning is more than just doing multiplication or division.

It is about understanding situations in which multiplication or division is an

appropriate operation.

It involves a way of viewing situations and thinking about them.”

(NCTM, 2007)

Big Ideas

Read a portion of the article relating to the “Multiplication Big Idea” assigned to your group

Develop a poster (on 11x17 paper) that clearly explains the big idea

So why don’t students know

their facts?

Fact Recommendations

Find out what they don’t know

Make multi-use, self-check flash cards for the facts they don’t know

“Facts I Know” and “Facts I’m Still Working On” bags
