The Situation

The Challenge(s)

- How can we tell where to cut the butter so you have 1/3 of a cup?
- How can we tell where to cut the butter so you have 1/2 of a cup?
- How can we tell where to cut the butter so you have 2/4 of a cup?
- How can we tell where to cut the butter so you have 1/8 of a cup?
- How can we tell where to cut the butter so you have a whole cup?
- How can we tell if 1/3 of a cup is more than 1/4 of a cup?
- How can we tell if 1/3 of a cup is more than 1/2 of a cup?

Question(s) To Ask

- What is a guess that is too small?

Begin by showing students the image below:

If students are having significant trouble finding 1/3 of a cup and you wish to scaffold the activity, you can ask them to find 1/2 of a cup first. The image below has the “1/2 cup” on the image but the “1/3 cup” is still missing.

Finally, when they are ready for the reveal, here is the original image:

It may be useful for students to have a template with the same scale for comparison purposes so I have included a PDF of the template below when you click on the “Download files” button.

Gioseppo Plomo ALANA ALANA ALANA ALANA Gioseppo Plomo Plomo Gioseppo Gioseppo Plomo Gioseppo Gioseppo ALANA Plomo Gioseppo Plomo ALANAPingback: Mr. Jones’ 3rd and 4th Grade Math Filing Cabinet | The Math Lab @ Room 27I am planning on using this butter activity as an opening question to a linear equation lessons in culinary. After asking the students I will have them plug in the values of (0,0) , (4 tbsp to 1/4 cup), (8 tbsp to 1/2 cup) and do a linear regression in Desmos. However, using the linear model will result in 5.33 tbsp to a 1/3 cup, while the label shows that its past 6 tbsp. I think this can lead to confusion?

Thanks!

Hi Thea. I think I understand where the confusion is. Yes, the marking for 1/3 of a cup is between 5 tablespoons and 6 tablespoons. You may be making the assumption that this means it is more than 6. To me, I assume that it is 5 full tablespoons and 1/3 of the 6th tablespoon. So, the label and the regression match up.

That being said, it does look like the line on the label is closer to 5 1/4 tablespoons instead of 5 1/3 tablespoons, so there is an issue there.

The label does show 5 and 1/3 Tbsp. The line is 1/3 of the way through the 6th Tbsp. not all the way through the 6.
