Combinations We are Still
Working On
Work with your group to create a list of five
multiplication combinations that you all
do not know and that you think will be
the most difficult to learn.
Continue to work together to use
multiplication combinations you know to
help you learn the combinations you do
not know.
Discussion
What multiplication combinations did your
groups find the most difficult to learn?
Let’s choose one multiplication
combination and discuss strategies to
learn the combination.
How could we START the combination?
What would the next step be?
