Have you tried using **3-act tasks** to teach math? If not, read on because you’re missing out on an amazing learning tool! In this blog post, I’ll share some fractions 3 act tasks that can be used in third, fourth, and fifth grade.

Teaching fractions usually starts with helping students recognize that a whole can be divided into equal parts. Then they learn how to name those parts by writing a fraction with a numerator and denominator.

Fractions in 3rd grade mostly focuses on recognition and involves little to no problem solving. But by 5th grade, students are expected to manipulate fractions and use them to solve real-world problems. It’s a big jump to make in just a couple of years and many kids struggle.

So how can you help your learners understand fractions in a deep and meaningful way? One of the most effective (and FUN) ways to teach fractions is to incorporate three-act tasks into your math lessons.

**What is a 3-Act Math Task?**

A three act task is a problem-solving activity, first developed by Dan Meyer, that consists of three distinct parts:

**Act 1:**Students are shown a photo or short video that presents an interesting and perplexing situation. This “hook” causes them to ponder and wonder about the situation and create a list of questions. As a group, students come up a focus question that can be answered mathematically.**Act 2:**In the next step, students try to solve their focus question through an information and solution-seeking session. They decide if they have enough information to answer the question and if not, what other new information would help them (which the teacher then provides).**Act 3:**Students discuss their strategies and possible solutions. The teacher may guide them in comparing their ideas and help them confirm that their answer is correct.

.

This procedure helps students explore math through real world problems and develop a range of strategies on their own through productive struggle. A distinct aspect of 3 act tasks is that they are driven by student voice and choice. They can be used in guided math groups or during whole group lessons or number talks.

No matter what topic you are covering in math class or what grade level you teach, you can use 3-act tasks. The complexity of the problems depends entirely on what your students come up with.

**Fractions 3 Act Tasks**

One of my favorite fractions 3-act tasks involves **CHOCOLATE BARS**! This activity can be adapted for 3rd through 5th grade because the students themselves define the problem.

Here’s how it works:

**Act 1**

Ask students – What can you observe about this picture? What questions do you have?

.

.

Possible responses:

- There are 4 candy bars.
- The candy bars are broken.
- Each candy bar has 3 pieces broken off.
- Each candy bar has 6 pieces that are not broken.
- What fraction of the candy is broken?
- What fraction of the candy is whole?
- If our class shares the candy, what fraction of a candy bar would we each get?

.

**Act 2**

Students decide on a focus question and seek additional information if needed. When I did this activity with 4th graders, they wanted to know:

- Is this a picture of 4 candy bars or 1 candy bar broken into 4 sections?

Hmm, very interesting idea.

.

**Act 3**

Students discuss strategies and solutions with each other. My 4th graders** **eventually agreed that:

- 3/9 of each candy bar was broken if there were four bars.
- 12/36 was broken if the picture was really showing one bar.

.

Then someone noticed that 1/3 of each bar was broken. This led to the discovery (all on their own) that 3/9 and 12/36 and 1/3 are all equivalent fractions. AMAZING!

.

.

Since I teach math intervention, I adapted the same fractions 3 act tasks for my other groups.

.

**Fractions 3 Act Tasks in 5th Grade**

I showed my fifth graders the same candy bar picture. Through their discussion, they figured out that 3/9 x 4 = 12/9 which is the same as 9/9 + 3/9. This led them to realize that the broken pieces shown in the picture are equal to 1 whole candy bar plus 1/3 of a candy bar.

At the end of our group time, we had a little celebration and enjoyed some chocolate as a reward for hard work! (Check out these other great Classroom Reward Ideas.)

**Fractions 3 Act Tasks in 3rd Grade**

Next, I went to third grade where we were learning to identify and name simple fractions. I showed them a different picture:

.

Their fractions 3 act tasks went like this:

**Act 1**

These are kids’ feet. They are all wearing different kinds of shoes. They look like shoes we wear. The shoes are different colors. Some shoes have laces and some don’t. Some look like girls’ shoes and some look like boys’. What kind of shoes are we wearing? Do all of our shoes have laces? If only some of our shoes have laces, that’s a fraction.

**Act 2**

The students in this group decided they wanted to know what fraction of them were wearing shoes with laces. They made a list of questions that would help them arrive at a solution:

- How many people are in our group? 8
- How many shoes do we have in all? 16
- What kinds of shoes are we wearing? tennis shoes, sandals, and boots

.

**Act 3**

The kids decided to take their shoes off (yep!) and sort them into piles. Then they collected data:

Their data showed that 5/8 of the students in our group had shoes with laces. During their discussion, someone pointed out that 10/16 of the shoes had laces. Although they didn’t realize that these two fractions are equivalent, it was a good observation. So, I pointed out that the fractions were different but the shoes had not changed.

Finally, several of the kids noted that more of them had laced shoes than not, so 5/8 must be bigger than 3/8. And we hadn’t even started learning to compare fractions!!
