This pack consists of 3 card-sorting activities which focus on working with different representations. Activities 1 and 2 focus on points while Activity 3 focuses on the linear function. The activities are aimed at Grade 9 level but could be used for different purposes at Grade 8 and 10 level. We believe the activities help learners to make connections between different representations of the same mathematical object.
Documented forms of learner errors when working with integers. The literature has identified some problematic ways in which learners can reason about integers.
Learners are introduced to negative numbers early in Grade 8. However, we know from experience and from our research that many Grade 9 learners still struggle to work with negative numbers. This impacts their work in many areas of the curriculum, particularly algebra and functions.
In this pack we propose a sequence of 5 one-hour lessons to revise negative numbers with Grade 9 learners. We refer to “negative numbers” rather than “integers” because our materials also include a small amount of work with negative fractions.
