Salting the Driveway [Day 1]
Posted by Kyle Pearce on March 9, 2021 at 1:32 pmHow do you plan to use this task?
After reviewing the Teacher Guide, do you still have any wonders or worries?
Once you’ve used the task, be sure to share what modifications you made either before or during the task and what you might do differently next time.

I’m excited to use this next week with my 6th grade students!

Awesome! Please do let us know how it goes. Photos of student approaches are always appreciated, too!

I teach high school calculus. I am embarrassed to admit that I can’t visualize/conceptualize dividing fractions. I am really good at algorithms and what my teachers taught me. I’m trying to see how dividing fractions actually works. This summer I want to practice using these tasks on my own children to be sure they have a better visualization/representation than I have. My question is, where can I find books/websites on how to divide fractions by fractions? Is there a guide I can use this summer with my kids on strengthening their decimal, fraction and overall number sense? I know I can pick and choose through your tasks, but wanted to check where you would start this adventure?

What a brave soul you are to head down this path. We too did not know why “multiplying and flipping the second” worked and that caused us to go down a huge journey that is necessary for building conceptual understanding.
Since there are two types of division (who knew!) I might start there first with the Sowing Seeds unit. Then, look at Planting Flowers to dig a bit deeper. Then I’d head to Salting the Driveway and Pizza Party. The teacher guides are really explicit and will help you along that journey. Also there is a session on division from last years Virtual Summit by Yvette Lehman that would be helpful.
As for books – there are some on fractions in general, but I haven’t seen any that really help with the dividing of fractions partly due to the fact that most ignore (or are unaware) of the fact that there are two types of division.

Hello! I was preparing to use this lesson for my 6th graders, however, I was having my own math moment and realized I do not really know how to use the double number line efficiently when it comes to fractions. Our class has worked with double number lines and ratio tables all year so I was excited to see them being used here too. But it seems like i only know how to use these models when the dividend is larger than the divisor. How do I solve problems such as 1/5 divided by 2/3? Thank you for this awesome lesson!

Hi Sarah,
This unit is a great unit to practice these ideas for partitive division.
The unit called Pizza Party is great for quotative division.So when you ask about a fraction Ă· by a fraction, the real question is… which type of division is it? Once we know that (easier if we use the context to guide us) we can then help to describe and model it.
Does that make sense?
