We always use this activity before students work on math together, as it helps improve group interactions. Teachers who have tried this activity have been pleased by students' thoughtful responses and have found students' thoughts and words helpful in creating a positive and supportive environment. The first thing to do is to ask students, in groups, to reflect on things they don't like people to say or do in a group when they are working on math together. Students come up with quite a few important ideas, such as not liking people to give away the answer, to rush through the work, or to ignore other people's ideas. When students have had enough time in groups brainstorming, collect the ideas. We usually do this by making a What We Don't Like list or chart and asking each group to contribute one idea, moving around the room until a few good ideas have been shared. Then we do the same for What We Do Like, creating a list or chart as a class. It can be useful to present the final charts to the class as agreed-on classroom norms that you and they can reflect back on, and add to, over the year. If any student shares a comment that casts others in a negative light, such as "I don't like waiting for slow people," do not put it on the chart; instead use it as a chance to discuss the issue and remind students that everyone's needs and ideas are important. This rarely happens, and students are usually very thoughtful and respectful in the ideas they share.
One of the most important topics in mathematics is reasoning. Scientists prove or disprove ideas by finding cases. Mathematicians prove their ideas by reasoning-making logical connections between ideas. This activity gives students an opportunity to learn to reason really well by convincing others who pose questions.
Before beginning the activity, explain to students that their role is to share their thinking and be convincing. Students may well be unfamiliar with what it means to convince, and you may want to give examples from students' everyday lives to illustrate what it means to be convinced of an idea. The easiest person to convince is yourself. A higher level of being convincing is to convince a friend, and the highest level of all is to convince a skeptic, someone who is unsure or doubtful. Just as important as convincing a skeptic is learning to be the skeptic. For young children, this first involves learning to attend to one another's ideas and ask questions about them. In this activity, we ask students to grapple with these three roles, making their thinking public to others, constructing arguments that convince, and listening to and questioning one another's thinking.
For this activity, we present students with an image and simply ask, "How many do you see?" On the face of it, this seems like a closed question, one with a single right answer and little reasoning. However, figuring out how many involves students in reasoning about what to count, finding ways to count when they cannot touch each object, and noticing structures in the image that can help them determine how many. The images we provide are complex, with several different types of objects that could be counted. Sometimes objects are arranged in a structured way, while other objects may be clustered randomly. Students might notice groups and use subitizing, composing, or decomposing to determine how many they think there are. Even when students arrive at the same answer for the same groups, they very well may have seen the quantities differently. We have provided four images you can use for this task, but you can find additional images in Christopher Danielson's (2018) How Many? or create your own out of objects in your classroom or school.
The idea in this activity is to encourage students to pay attention to and share their thinking. They must learn to listen to and wonder about the thinking of their peers. If one student is struggling to understand how another student saw the objects, encourage them to ask a question, such as, "Where did you see five?" or "Can you show me?" These are opportunities for everyone to learn that everyone's thinking is valued, that posing questions is something mathematicians do, and that explaining our thinking is how we convince one another.
