Learning Objectives
Grade D
To be able to explain the method for number
problems using trial and improvement.
When do you know you have the correct
answer?
Grade C
To be able to explain the method for
solving equations using trial and improvement.
When can we can be confident about a set
degree of accuracy?
Grade B
To be able to recognise the shapes of the
graphs y = x3 and y=1/x.
How many solutions could you expect to from
cubic equation?
Resources
Grade D
Grade C
Ten Ticks - 7-8, 3, page 28
Grade B
Introduce cubic function
Now move on to look a reciprocal functions.
Guide students to recognise the properties
of different graphs:
Homework:
Using Trial and Improvement solve the following equation to 3DP
x^5 - x^2 + 5 = 0
Hint: the solution is between -1.5 and -1.0
Email a picture of your answer and workings before the first lesson next week.
