Interactive practice problems based on American algebra 1, geometry, and algebra 2 syllabi. Instant feedback to students. Good variety of problems on each page.
Interactive problems on a variety of topics, units, concepts. Based on the British curriculum. No feedback for teacher so good for kids own self-assessment. All levels up to grade 9/10 are included.
KS 3 = Middle school. GCSE = Grade 9/10 (and possible some grade 8).
This could be good after the calculus exam is done in May.
Others could use it as a springboard for HL "exploration" etc.
Basically this is a reminder of the richness of resources available on NRich.
