Teaching Shapes and Their Attributes to K–2 Students

Teaching shapes and their attributes is an important part of early elementary education. One thing to remember when you are introducing shapes and their attributes is that students go through sequential stages of development when they learn about shapes. The stages were identified by Pierre van Hiele, who described his theory in Structure and Insight (1986). Clements and Battista further refined the stages in 1992[i].

Polya’s Problem-Solving Steps: Finding Unknowns Elementary and Middle School

It is unfortunate that in the United States mathematics has a reputation for being dry and uninteresting. I hear this more from adults than I do from children—in fact, I find that children are naturally curious about how math works and how it relates to the world around them. It is from adults that they get the idea that math is dry, boring, and unrelated to their lives. Despite what children may or may not hear about math, I focus on making instruction exciting and showing my students that math applicable to their lives.

Mean Absolute Deviation and the Concept of Variability in Middle School

Recently, I was working with some of my students on topics they had failed in last year’s state testing. The topic of the day was mean absolute deviation, and while they were able to perform the calculations, they were struggling with the concept of statistical variability.

How to Create Rubrics That Will Enhance STEAM Projects in the Math Classroom

A few years ago, we wanted to start a robotics club in our school. When I say we, I mean the school’s students, parents, and administration. While all the teachers thought it was a good idea, there was one big question—who was going to step up to the plate to lead the effort? None of the faculty had ever built a robot, never mind teaching a student to do so! As a result, I volunteered to start the robotics club with the understanding that I would have to learn along with the students.

Math Center Ideas That Will Make Implementation a Success

One of the hardest things to do is change the way we teach. We learn in educational programs that engaging students with each other and individualizing instruction are some of the keys to keeping students on track. Yet I sometimes find myself stuck in the mode of “talk and chalk,” leading the whole class through “I do, we do together, you do” activities. One of the solutions to getting out of this pattern of whole group instruction is the use of rotations and math centers. I am including one of my favorite math center activities as a download for this post.

How to Improve Mathematical Discourse in Your Classroom

It has been difficult for me to learn how to stimulate vibrant discussions about mathematics among students. I realized very early in my teaching career that in order to get students engaged in mathematical discourse I needed to foster community in the classroom, to help students feel safe expressing ideas, and to demonstrate that math can be fun!
