Abstract
The equivalence relation exhibited as an equals sign is misunderstood by students who consider it to mean . 'do something', to indicate the location of the answer and to act as a separator symbol. This presentation reports on a cross-sectional study of students in years P, 2; 4, 6, 8 and 10 to explore understanding of equals and equivalence, conceptions of same and different and knowledge of the properties of equivalence . and approaches to the equals sign. Students appeared to predominantly have cm openitor ('do something') understandihg of equals, and to exhibit differing understandingsof equals in situations such as 2+3=?, 2+3=5 and x+3=5. of the three properties (reflexivity, symmetry and transitivity) and of the two approaches (static and dynamic)
