reminder for block test
Monday, August 2, 2010 @ 5:55 AM
REMINDER ON MATH BLOCK TEST 2.
THIS IS TO MAKE SURE THAT EVERYONE KNOWS THE TOPICS THAT ARE TESTED:
TOPICS THAT ARE TESTED:
basic algebra
-substitue values
-e.g. a= 3, b= -3, c= 3/4. find the value of (a+b^2)/c
-combine like terms and simplify expression
-e.g.simplify 2a + 7b - 13a + 8b^2
expansion
-expand 2 terms
-e.g.(2a +3)(-b -3)
-expand 3 terms
-e.g.(3+a(2a-1)(b+a)
-expand a combination of terms
-e.g.2x(9x-3)+x(3-x)(2x+1)
factorisation
-factorise by taking out HCF
-e.g.16u^2 + 4u + (2u)^2
-factorise by grouping
-e.g.4xy + 8y - ax -2a
-factorise by using perfect squares formula
-e.g.16a^2 + 56ab + 49b^2
-factorise by using the difference of 2 squares
-e.g.9 - (a+b)^2
-use factorisation technique instead of calculator to solve problems
-e.g.345^2 - 55^2
solving linear equations
-identify linear equations
-solve linear equations involving expansion
-solve linear equations involvng cross multiplication/expressing as common denominator
geometrical properties
-know the types of angles and what they mean(eg obtuse angle)
-know how to write reasons properly(presentation)
-know the basic geometrical properties involving equality of angles(alt angles, corres. angles etc)
number sequence
-practice questions from the revision exercises booklet to be familiar with a range of questions.
this are the topics tested:DGood luck for blocks tomorrow
