Solving Equations
Learning intention – Equations with
Fractions
Success Criteria – able to identify
LCM of the denominators, then knows
how to multiply by LCM to eliminate all
fractions
Ex 12.3
page 139
It may be useful to
begin lesson with a
starter to remind
pupils of how to
multiply by a fraction.
i.e.
2/5 X 30 =
3
Special Notes
Homework
Remind class of the basic
rules, i.e. “xs to one side,
numbers to the other”,
“change the side, chamge
the sign”, “if it’s stuck to the
x then it goes underneth on
the other side” etc..
Illustrate with plenty of well
set down examples.
Reminders of multiplying out
brackets and collecting like
terms.
Illustrate with more selected
examples.
none
Show clear examples on the
board.
Expressions like (X+2)²
should be written as
(x+2)(x+2), leaving the
associated rule to another
day.
Beginning with simple
examples, illustrate the
method on the board.

the inequality sign if dividing or
multiplying by a negative, knows how
to deal with fractions and brackets,
knows the condition for turning the
inequality sign round.

Remember remember
page 143
Illustrate the same method
for dealing with fractions and
clearly show how to apply it
to the new format of fraction.
Define an inequation and go
over all the inequality signs.
Do some straight forward
examples which have the
same familiar steps as
solving an ordinary equation.
Explain when to reverse the
inequality sign and illustrate
with suitable examples.
Give further examples of
type seen in questions 6, 7
and 8.
Do as many as necessary.
