This task best fits 3.NF.A.3.a-b as an introduction to equivalent fractions.
What did you notice? What do you wonder?
Focus Question: How many will go on each plate so that everyone gets the same amount?
How many full bars were there?
What if the bars were cut in fourths and eighths?
This task is a little different than most, but I really think it has some good exploration built in and it lends itself to more of an open task. The standards that I think best fit this task are Math Practice 1, 3, and 4. If you think there is a good fit with a content standard, please comment below. There is definitely some partitioning of the whole which could be a good application of 3.GA.2.

Focus Question: How will the bread be cut?
I made 7 cuts. Number of Pretzels
This task is meant to emphasize partitioning on a line of symmetry. Common Core Standard 4.G.A.3.
What did you notice? What do you wonder?
Focus Question: Where will I need to cut the heart for it to be symmetrical (or to cover itself)?
Use this recording sheet for students.
I happened upon some Little Debbie snacks at the grocery store a few days ago and got some ideas for some new tasks. This task is meant to show fractions as division by dividing the number of Ho Ho’s by the number of plates (or people). The common core standard this best fits is 5.NF.B.3.
What do you notice? What do you wonder?
Focus Question: How many Ho Ho snacks will each person (or plate) get?
