When I go online to a Facebook Group on Building Thinking Classrooms and mathematical mindset, I see teachers often giving each other advice about gifted kids. I hear the phrase, "Go deeper with your kids rather than accelerate." However, I find that many people aren't sure what going deeper means or how to teach in that manner.
When I think about how to go deeper in a concept, the Math Practice Standards come to mind.
Many times my students have memorized an algorithm that is above their grade level and know when to apply it, but don't understand what is happening with the numbers within the algorithm. It becomes apparent when I ask them to explain why the partial product strategy works, or why you can take a one away from the ten. This is why place value charts, models, labeled diagrams, and the like are important.
In this dynamic world, my students need to be flexible thinkers and problem solvers as they work on complex problems. It is imperative that they explain their thinking to others, so collaboration can occur and we, as a society, can discover multiple solutions to problems and chose the most effective one.
One way we work on this is through Math Talks in the debrief section of my lesson, which gets at Math Practice 3. I ask students to explain someone else's work based on their notes on a whiteboard or worksheet. Students have to be able to interpret what the student understood and find places to "nudge" them a little further in their learning journey.
For example, yesterday I pushed into a classroom for some problem solving. I allowed students to chose from 4 different problems and work in partners or groups on the problems. There was a problem about splitting brownies, which was similar to one we already worked on, a complex problem about how many ways can you solve a problem, a communications problem where student wrote a fraction story, and finally one with constraints and rules to find a mystery number. To find similar problems, click here.
During the debrief, I asked for students who were willing to put their work under the document camera to be talked about. A few students raised their hands and wanted to share. I placed their work under the document camera, and had the student take a seat and sit silently. The work had great ideas in it and small errors as well.
When the first student placed her work under the document camera, I asked, "What does this student understand?" We would talk about how the student was dividing brownies correctly, writing fractions accurately, and distributing them evenly. Then I would ask, "What could we say to this student to nudge them a little on their learning journey?" Students shared that we need to consider the last brownie (which was left out).
We did this again with a student attempting to add fractions, but was needing to consider how unlike denominators affect the addition. I like how students are oriented toward each others' work and communicating clearly, and I also like how many notes need to be on the page for someone else to analyze the work. Students talk with one another and the class as we look at each other's learning journeys and offer tips and tricks.
It's a work in practice. Every day I get a little better at facilitating and the kids push their learning a bit further, but its productive and helpful in the long run.
