My school professional learning community has focused on student discussion in mathematics and problem solving over the past two school years. My students are developing more and more skills for problem-solving.
First, students follow a week long process with problem-solving that I developed with a colleague, Carina Pruitt, based on research and professional reading, How To Solve It, By G.Polya. We took the approach for a week long practice so students had time to get to know the problem, have extended time to discuss the problem, and come up with a strategy to solve the problem. All of this is done with a partner to give support, offer discussion and debate for students as they solve.
Here is sample problem my students have been solving:
The principal wants to buy 8 pencils for every student at her school. There are 859 students in the school.
You will notice there is no question with the information. On the first day students simply list the things that are "known" and "unknown" in the problem and craft questions you could ask for the given information. This is a day of getting to know the information and the problem with their partner. On the second day students are given the question and write a strategy statement. What is the question asking them to find, what do they know and what math strategy will they use to find the solution. They then work to create a visual model and then a number model to solve the problem. Students do all of these steps with paper and pencil.
It is on the third day that they take the problem solving digital. They work with their partner and solve the problem with visual and voice recording. We use the app Doceri, but Explain Everything and other screencasting apps work just as well. Here is a student sample of the above problem. The question they were answering is how many pencils will the principal need to buy for every student to have 8 pencils.
Students submit the videos to a Google Classroom assignment, but as you know, that limits to just being viewed and given feedback by me, the teacher. BUT, Google Classroom has the ability to post videos to a class wide thread.
This week I will ask students to submit the video as an assignment, but also post it to the assignment as a new post to the class, the video because it was uploaded to the assignment is stored in the student's Classroom Drive Folder, by posting it to the class pages others can view it, see different thinking and leave a comment for the student, the discussion around this problem has now grown to a new thought partner. If each student watches another video from someone in his/her assigned group (meaning they solved the same problem), they are being critical of others' work, improving their math discussion and ability to give feedback, possibily learning some new information as well!
