Numeracy Help Mat
This resource contains two pages which can be printed back-to-back and laminated for continued use.
It displays a number line, counting square, multiplication grid, Fraction, Decimal and Percentages conversions as well as different shapes and keywords.
I have used this with classes ranging from Year 7 right through to GCSE though predominantly with the foundation sets. I found it really useful in lessons such as Highest common factor and lowest common multiple where timetable knowledge can really slow the students down.
