There are a few of the myths that I have encountered, not only as a student, but I’m seeing these in colleagues when they teach.
1. There is always one best way to do a math problem.
2. It’s wrong to count on your fingers.
I was always taught how to do math problems one way, but as I continue in my career, I’m finding that students who struggle often find it helpful to have things explained to them another way. A colleague of mine wants me to teach students a certain way to work with fractions, so that when they get to her they are used to doing it that way. But I have found that as long as they understand the process and are finding the answer, there usually is more than one way to solve the problem.
I have heard many math teachers complain that students in middle school and high school are still counting on their fingers. In fact, I used to be one of those teachers who would complain, but this goes along with the myth that there is only one way to do the problem. Some students need the visual of their fingers to help them add or subtract. Right now my daughter is learning addition and subtraction facts in 2nd grade and I have told her that if she needs to use her fingers to help count up or down, then she should go ahead and do that.
I can encourage students to figure out why we are solving problems, not just emphasize to them that they need the right answer. I need to tell students that there are different ways of solving problems and to encourage them to think of more than one way to solve a problem. This will help with their critical thinking skills as they get older.
Jackie,
Your students do need concrete items to help them better understand the math. If fingers are handy them letting the students use them is a plus! We do want to move away from the concrete representation and develop the abstract when students are ready.

Jackie,
I too am a teacher who gets frustrated when students count on their fingers but am working toward being more understanding. I have always thought that students who count on their fingers are being lazy and are not using the math facts that they should have memorized. Lately, though, I’ve really started noticing that using their fingers helps some students understand better. Now I’m trying to overlook the counting on their fingers and simply encourage them to find a method that works for them.
