There are four basic language abilities, and each one is also widely used in math. 1. Students listento us talking, presenting and explaining 2. They read their textbooks, worksheets, and displays 3. They present their math by drawing and writing 4. They askquestions and discuss their ideas to improve their understanding of mathematical concepts Un...
Steve Chinn (2004) in ‘The Trouble with Math’ argues that the dual terminology of math is a real problem. The colloquial nature of some common math words and phrases means that students may well have to cope with inconsistencies, which, as we know, doesn’t always turn out well! Clearly students have a lot to cope with when they are sifting and sort...
Although as teachers, we might be vigilant about the everyday mathematical words we use in the classroom, there are some ‘false friends’ that might confuse even us. This means that we’ll then allow students to use them incorrectly too. I’m thinking of the common question you will no doubt have seen a number of times in relation to a chessboard inve...
A lack of precise language can impede students’ understanding and can easily lead to a lifelong development of misconceptions in math. Although in our everyday life we can cope with a fair amount of ambiguity, in mathematics ambiguity causes problems so it’s not welcome. A few years ago, I became all evangelical about the way students were taught m...
My number one bugbear was the use of the word ‘square’ as a noun rather than an adjective. When I started to look at definitions in math textbooks, math dictionaries and online materials, I could see that there was a major problem as their definitions were often ambiguous too. Take a look at a math dictionary yourself and look up ‘rectangle’ and ‘s...
I repeated the square and rectangle experiment once when I delivered an inset session at a ‘gifted and talented’ math day. Initially most teachers laughed and shook their heads as I asked them to draw a rectangle. After all, they had come to learn all about helping able mathematicians and looked bemused that they were being asked to draw a rectangl...
If ever I am teaching a known math misconception, and there are many, I put on a ‘Hi Vis’ vest as a signal to the class that they are about to be challenged. They find the ‘Hi Vis’ jacket a fun novelty, but they also know that wearing one means that they have to be on their guard because I am going to challenge their thinking and they are going to ...
A very common activity when teaching geometry is to go on a shape hunt. Students are split into groups and look around the school, searching for examples of circles, triangles, squares, rectangles and more. After a while, everyone comes back and shares what they have found and where they have found them. Then there’s a discussion about the shapes f...
At Third Space Learning, tutors are trained very specifically to use math terms correctly and there are a number of resources on math vocabulary that form the basis of this: 1. This math vocabularylist for elementary students looks at the principal mathematical words that students should know and provides a free downloadable vocabulary list for stu...

May 2, 2024 · Algebra: The branch of mathematics that substitutes letters for numbers to solve for unknown values. Algorithm: A procedure or set of steps used to solve a mathematical computation. Angle: Two rays sharing the same endpoint (called the angle vertex). Angle Bisector: The line dividing an angle into two equal angles.
