KS3 Numeracy Year 8
Consolidating Numeracy

Use these Consolidating Numeracy sessions to check that your students' numeracy is and remains secure and fluent through Key Stage 3. Each session has additional teaching material in case you find they need some revision of concepts and procedures.

Each Unit consists of three ‘starters’ - two slides in a PowerPoint presentation designed to provide some quick numeracy revision to be done at the start of the maths lesson. This revision takes no more than 10-12 minutes. This revision can be done at the beginning of each maths lesson in the week.

If the students show that they have not mastered this aspect of numeracy and are not demonstrating fluency, there are further slides which may be used to teach and consolidate the topic. This further teaching can be used on that day, replacing the planned lesson, or can be factored in to the medium term planning to be taught at a later time.
