These activities begin with multiplication, but are focused on using Cuisenaire Rods on a meter stick or number line to divide.
For teaching basic division, everything goes that’s on my summary for basic multiplication:
"In my 30+ years of teaching Math I have yet to see a better way of
introducing multiplication and division than with Cuisenaire Rods….
For teachers who don’t have Cuisenaire Rods, there is an alternative
way of doing somewhat the same thing on a number line, by coloring
segments of each multiple with alternating colors."
An image of how this works is on the cover page. Note that using Cuisenaire Rods is an ideal way to teach fact families.
This is a “repeated addition” model of multiplication. If you’re particular about what type of division problems you are giving your students, it’s “measurement division.”
These number lines are sized for legal paper. They only extend to 81 because if they were any smaller they’d be difficult to read and color in -- after 81, the only problems left are 90 ÷ 9 and 10, and 100 ÷ 10.
This lesson includes one page for each multiple 2 – 9. There are also several pages of practice problems including both fact practice ( 36 ÷ 9 = ___ ) and missing factor problems ( 36 ÷ ____ = 9 ) .
Common Core Standards:
