Thinking and Working Mathematically Thinking and Working Mathematically There are some important skills that you will develop as you learn mathematics. Specialising is when I give an example of something that fits a rule or pattern. Characterising is when I explain how a group of things are the same. Generalising is when I explain a rule or pattern.
Classifying is when I put things into groups. 6 Original material © Cambridge University Press 2021. This material is not final and is subject to further changes prior to publication. are working with Cambridge Assessment International Education towards endorsement of this title.
Thinking and Working Mathematically Critiquing is when I think about what is good and what could be better in my work or someone else’s work. Improving is when I try to make my work better. Conjecturing is when I think of an idea or question to develop my understanding. Convincing is when I explain my thinking to someone else, to help them understand.
