Level 8 – ASSESSMENT CRITERIA
Number and Algebra
decimals: 3/5, 3/11,7/30, 9/22, 9/20
as a fraction in its simplest terms
standard form function on a scientific calculator
o
I can factorise quadratic expressions including the difference of 2 squares
e.g.
x²– 9 = (x + 3) (x – 3)
I can factorise the following expressions: m²– 2m – 8
-3)² giving my answer in its simplest
form
-3)² - (2x+3)² = -24x
derive and use a more complex formulae e.g.
o To cook a chicken allow 20 minutes per 1⁄2 kg and another 20 minutes. A
chicken weighs ‘x’ kg. Write an expression to show the number of minutes ‘m’
to cook a chicken.
. Given the perimeter p of a semicircle
with radius r is p = r (π + 2), rearrange the formula so that r is the subject
negative numbers
set e.g.
o
I can write the 3 inequalities to describe fully the shaded
region.
I can sketch, identify and interpret graphs of linear, quadratic, cubic and
reciprocal functions, and graphs that model real situations
constant e.g.
o Given the graph of y=x² I could use it to help sketch the graphs of
y=3x²and y=x²+3
Level 8 ASSESSMENT CRITERIA
Geometry and Measures, Statistics
I understand and can use congruence and mathematical similarity
understand and can use trigonometrical relationships in right-angled
triangles, and use these to solve problems, including those involving
bearings
I can identify the correct expressions / formulae for perimeter, area
and volume by considering dimensions e.g.
o I can identify which of the following expressions represent an area
if 'a', 'b' and 'c' are lengths:
ab+bc, 4abc, 5a+6b, 3ab² 2ab-c c(3b-2a)
I can compare two or more distributions and make inferences, using
the shape of the distributions and measures of average and spread
including median and quartiles
I know when to add or multiply two probabilities e.g. I can show you
an example of a problem which
o could be solved by adding probabilities
o could be solved by multiplying probabilities
I can use tree diagrams to calculate probabilities of combinations of
independent events e.g. I could solve this problem
o The probability that Nora fails her driving theory test on the first
attempt is 0.1. The probability that she passes her practical test on
the first attempt is 0.6. Complete a tree diagram based on this
information and use it to find the probability that she passes both
tests on the first attempt.
