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.)
- 13% of 48 =?
- I can calculate an increase of 15% on an original cost of £12
- The angles in a triangle are in the ratio 6:5:7. Find the sizes of the three angles
£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)
- you start with 100 and subtract 5 each time
- the nth term is 2n - 0.5
- 7, 12, 17, 22, 27, ... and 4, -2, -8, -14, -20, ...
- I can plot the graph of y = 2x – 3
- y = 2x + 4 and y = 2x – 3
- y = 3x – 2 and y = -3x + 4
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 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 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
