Level 6 – ASSESSMENT CRITERIA
Number and Algebra / Level 6 ASSESSMENT CRITERIA
Geometry and Measures, Statistics
 I can convert fraction and decimal operators to percentage operators by multiplying by 100 e.g.
  • 0.45; 0.45 × 100% = 45%
  • 7/12; (7 ÷ 12) × 100% = 58.3% (1 d.p.)
 I can use mental and written methods for finding percentages of quantities e.g.
  • 13% of 48 =?
 I can find the outcome of a given percentage increase or decrease. e.g.
  • I can calculate an increase of 15% on an original cost of £12
 I can solve problems involving ratio and direct proportion such as:
  • The angles in a triangle are in the ratio 6:5:7. Find the sizes of the three angles
 I can use unitary methods and multiplicative methods to solve problems (proportional reasoning) e.g. There was a 25% discount in a sale. A boy paid
£30 for a pair of jeans in the sale. What was the original price of the jeans?
 I can calculate confidently with fractions using all four operations e.g.
+ = ? - = ? x =? ÷ = ? and of 36 =?
 I can use trial and improvement for algebraic problems e.g. x3 + x = 20
 I can solve linear equations with integer coefficients e.g.
  • 3c – 7 = -13
  • 12/(x+1) = 21/(x + 4)
 I can generate the first five terms of a sequence e.g.
  • you start with 100 and subtract 5 each time
  • the nth term is 2n - 0.5
 I can find the nth term of a linear sequence e.g. of
  • 7, 12, 17, 22, 27, ... and 4, -2, -8, -14, -20, ...
 I can plot the graphs of simple linear functions using all four quadrants by generating co-ordinate pairs or a table of values e.g.
  • I can plot the graph of y = 2x – 3
 I understand the gradient and intercept in y = mx + c and describe similarities and differences of given straight line graphs e.g. I can compare these linear graphs without drawing them
  • y = 2x + 4 and y = 2x – 3
  • y = 3x – 2 and y = -3x + 4
 I can construct and interpret graphs arising from real life problems /  I can classify quadrilaterals by their geometric properties
 I can solve geometrical problems using properties of angles, parallel & intersecting lines, triangles & other properties e.g. I can explain why
equilateral triangles, squares and regular hexagons will tessellate on their own, but other regular polygons will not;
 I can identify alternate & corresponding angles
 I know the difference between demonstration & poof & can prove that the sum of the angles of a triangle is 180° & of a quadrilateral is 360°
 I can draw a square / hexagon / equilateral triangle using LOGO & use the instructions to compare with the exterior angles of a polygon
 I can visualise & use 2-D representations of 3-D objects
 I can construct an enlargement given the object, centre & scale factor
 I can find the centre & / or scale factor from the object & image
 I can find missing lengths / angles on diagrams for an object & its image
 I can use straight edge & compasses to construct
  • the mid-point & perpendicular bisector of a line segment
  • the bisector of an angle
  • the perpendicular from a point to a line
 I can calculate the area of a triangle & parallelogram
 I can calculate the volume & surface area of a cuboid;
 I can calculate the area & circumference of a circle
 I can design a survey or experiment to collect data
 I can design, test & if necessary refine data collection sheets
 I can construct tables for large discrete & continuous sets of raw data, choosing suitable class intervals
 I can construct on paper & using ICT:
  • pie charts for categorical data;
  • bar charts & frequency diagrams for discrete & continuous data;
  • simple time graphs for time series;
  • scatter graphs.
 I can draw conclusions from my tables/graphs/diagrams & decide if there is enough evidence to support my hypothesis
 I can use a possibility space diagram to show all outcomes
 I know that the sum of probabilities of all mutually exclusive outcomes is 1 & use this when solving problems
