## REPRESENTATIONS

## OVERVIEW

This half term we will be building on learners knowledge of coordinates from KS2 by looking formally at algebraic rules for straight lines starting with lines parallel to the coordinate axes but developing understanding of straight lines in the form y = mx + c and links graphs to sequences.

Following this learners are introduced to bivariate data and the concept of linear correlation. They will extend their knowledge from KS2 to work with both discrete and continuous data.

Building from Year 7 and earlier lessons on two way tables learners work with the idea of probability and how to calculate probabilities from two-way tables and Venn diagrams.
