Mathematics - Year 7


Year 7 at NHGS is the first year of our 2-year Key Stage 3 course. Students are taught in mixed ability form groups. Our course is based upon the Pearson, KS3 Progress in Mathematics Course. 

The students study the most challenging Delta course. The Delta course uses three student books. Year 7 students cover most of Delta 1 and some of Delta 2. The curriculum is divided up into 8 modules to cover during the course of the year. Each module taught has three difficulty levels, mastery, strengthen and extension. Through direction and negotiation with the teacher students are encouraged to work at the level that challenges them. This means that a class may be studying the same topic but students may be working at different levels of challenge. 

The Delta 1 books are issued to Year 7 allowing students to complete work independently at levels relevant to them and for parents to monitor the level of challenge that their child is experiencing in school. There are also two further levels of extension available to all students when appropriate, a set of challenge questions and a set of problem solving questions.

Students will have a designated investigation/problem solving lesson once a fortnight.

Homework is set each week and varies from consolidation, stretch and challenge to online learning and revision. Students have access to further optional, independent homework set online.


Assessment is a formal test after each module and a Year 7 assessment in the summer term. Emphasis is placed upon teachers and students diagnosing strengths and areas for improvement. Identified weaknesses are reviewed before progressing to new work.
