The document outlines key concepts and skills to be learned in an algebra lesson, including: - Simplifying algebraic expressions by collecting like terms - Expanding brackets - Multiplying algebraic expressions It then provides examples of simplifying algebraic expressions, expanding brackets, finding perimeters and areas of shapes, evaluating expressions, and converting between temperatures in Fahrenheit and Celsius.

1. By the end of the lesson you should be able to :
• Simplify algebraic expressions by gathering
like terms.
• Expand brackets.
• Multiply algebraic expressions.
Algebra

2. Simplify collecting like terms:
5xy ­ 2yx + 2y ­7 ­7y =
2x2
­ 5x ­12x2
­7x +3=

3. Remove brackets and simplify:
5a ­ ( ­ a + b ) =
4 x2
+ ( 3 ­ x2
)­ 2 x =
3 x ­ ( x
­ 5) + 2x +7
=

4. Simplify:
3 (­2)2
­ 5 (x ­ 2 ) =
(3 x)2
­ x2
=
2 (5a)2
­ (2 a + a2
) =

5. Find an expression for the perimeter of this
parallelogram and simplify it:

6. Find expressions for the perimeter and area of this
rectangle and simplify them:

7. The length and with of a rectangular picture frame
are shown on the diagram. The edging has width a.
Write and simplify an expression for the perimeter
of the picture which fits inside the frame.

8. Evaluate these expressions if
a= ­1 b= 3 c= ­2

9. To convert temperatures in degrees Fahrenheit
(o
F) into degrees Celsius (o
C) , this formula is
used:
where F is the temperature in o
F and C is the
temperature in o
C.
Convert these temperatures into o
C. Give your
answers to 2 d.p.
60o
F
212o
F
0o
F
­10o
