When I was in school, I was never asked what I knew, what I thought about, or how I processed mathematical information. I’m happy that this is different today and that valuing mathematical communication in today’s classrooms is recognized as important. Better known as mathematical discourse, whole-class discussions where students talk about mathematics can reveal their understanding of concepts. We owe it to our students to be curious and inquisitive about what they know or don’t know about their mathematics. Are you having conversations with your students about math?
Educators have the opportunity and privilege of teaching students how to participate in meaningful mathematical discourse. How do we begin? The opportunity for discourse starts by presenting students with, and engaging them in, rich mathematical tasks. Rich math tasks focus students’ attention on mathematical ideas and allow for the development/use of the mathematical habits of mind. Rich math tasks are not memorized procedures and facts, but engaging and powerful experiences. Teachers are no longer simply the transmitters of knowledge.
I suggest you set a goal for engaging your students in discourse, then formulate a plan to accomplish your goal. Questions keep students engaged and prompt them to think more deeply while the discourse happens organically. As part of your plan, I recommend that you craft a list of readily available questions to ask students in any situation. Here are some suggested questions:
- Can you convince the rest of us that your answer makes sense?
- Is this a reasonable answer?
- How did you think about the problem?
- What is another way you could have solved this problem?
- How did you reach that conclusion?
- How did you organize your information? Your thinking?
- Which skills or concepts did you use?
- What were the mathematical ideas in this problem?
Plan time to reflect on how the mathematical discussions have gone in your classroom. Check on the progress your students have made. Think about the student learning that is occurring. Revisit and revise your questions based on your reflections. I would like to hear your ideas about mathematical discourse in your class(es).
Are there any dangers in training your students in the “strategy” of counting-on? After reading Dr. Les Steffe’s work, I would argue it is harmful. He calls counting-on a non-teachable scheme. This means that if you want counting-on to be meaningful for students you can present situations that would promote their construction of counting-on, but… Continue Reading
I am writing this post from the annual conference of Learning Forward, an organization whose mission it is to “build the capacity of leaders to establish and sustain highly effective professional learning.” When I became the Mathematics Coordinator at the Fresno County Office of Education in 1998, I turned to this professional organization (then called… Continue Reading
Earlier this month my colleagues and I had the privilege of attending the National Association for the Education of Young Children Conference in Los Angeles. Professional learning is a wonderful opportunity where one can validate ideas, gain new insights, and network with others in the field. This was my first attendance at a preschool level… Continue Reading
There has been renewed interest among science educational researchers over the past decade in the power of “play” in the classroom. One of the researchers that I have been following is Dr. Kathy Hirsh-Pasek, a psychologist at Temple University. She is one of the founders of the Ultimate Block Party which brings together companies, makers,… Continue Reading
Lesley Gates joins us on the podcast this week. She briefly describes some of the goals, purposes, and benefits of the new science standards that are in the process of being incorporated in public schools across the US. With an emphasis on the “Doing” of science rather than reading about it from books; along with developing and fostering a sense of curiosity and wonder about the natural and human-made worlds, the NGSS hope to bring science back to a more prominent role in schooling than it has been over the last few decades. Lesley describes with great passion some of her hopes for these standards.
I hope that you have had the chance to personally experience an AIMS professional learning opportunity. We AIMS facilitators have multiple goals as we lead workshops. We provide classroom teachers an opportunity to increase and/or strengthen their own content knowledge, explore their teaching practices, and we strive to help teachers find ways to improve their… Continue Reading
This has been a big week of learning; learning to know new people, learning to know more about my work, more about the community of research, and more about myself. I will start with the latter. I tend to believe that I have a steady stream of curiosity. Every kid loves to ask “why?” and,… Continue Reading
When looking at coordinating units, it is important to consider concepts other than just multiplying. One of those is fractions. Fractions would be first among these encountered by a child in school. Mental operations that must develop for a child to understand fractional ideas include partitioning, iterating, and splitting. These developments are not taught, much… Continue Reading
In my last blog I mentioned that there are two distinct types of subitizing – perceptual and conceptual. I am fascinated by the subtle differences that students show and what that means about their thinking. Perceptual subitizing is the ability to recognize a number without using other mathematical processes (Clements 1999) and there are four… Continue Reading
