After a couple of weeks working with problems in which they were taking a fraction of a fraction, fraction of a mixed number, the students made some conjectures about the problems.
“Ok, isn’t this really just multiplication?”
I knew he just wanted an answer, but that was not going to happen. 🙂 Since we have been doing a lot of multiplication number talks, I thought I would see if I could make a connection to whole number operations.I said, “Well, if it is multiplication, do you think the strategies on our anchor chart should work for the fractions too?” We made the anchor chart as strategies arose in our number talks. I put 2 1/4 x 1/2 on the board and said, “Try it out.”
They worked in groups and came up with some pretty amazing stuff…(A couple students chose to try a different problem, so the sampling below may be a mix)
We are going to share some strategies tomorrow since the rest of the class period consisted of them “arguing” about fraction multiplication. It made my day when one of the girls was leaving my class and said to her friend, “That was so fun!”
Wait, fractions fun?? LOVE IT!
