If anyone is interested i found this about the TSA:
The Mathematical Knowledge and Skill Needed
Number Concepts
• simple fractions
• place value (for example, knowing that the "5" in "7654" indicates "50")
• ideas about percentages (for example, the idea that 1% could be thought of as "1 in every 100", and that if 20% of a group of adults are men, 80% must be women)
Numerical Operations
• the four rules of number (addition, subtraction, multiplication, division)
• percentage operations (for example, if something was sold at £10, and is now advertised at "20% off", how much would the customer pay?)
• calculations in everyday contexts (complex calculations with fractions and decimals are not required)
Quantities
• time and the calendar
• money
• length
• weight
• area
• volume
Knowledge of the following relationships is also required:
1 km = 1000 m
1 m = 100 cm
1 cm = 10 mm
1kg = 1000 g
Also required is knowledge of the terms for measurements which are used informally in daily life (e.g. feet, miles), but numerical relationships for these measures (e.g. 12 inches = 1 foot) are not required.
Space and Spatial Reasoning
• area (including the calculation of the area of a rectangle)
• perimeter (including calculation)
• volume (including the calculation of the volume of a box)
• reflections (in mirrors) and rotations of simple shapes • two-dimensional (2D) representations of three-dimensional (3D) shapes (for example being able to interpret a "bird's eye view" of a house)
Generalisation
• recognition that some operations are generalisable, for example that converting 24 to 3 and 40 to 5 both involve division by 8 (formal algebra is not required)
Tables and Graphs
• extracting information from graphs
• extracting information from tables
