LEARNING OBJECTIVE: TO revise weaker areas of Syllabus from mistakes and omissions from the practice paper
SUCCESS CRITERIA: You will be able to answer similar questions in future test papers.
STARTER: Hand outr papers and give students 5 mins to talk about / share their results
LESSON.
Question 1 – Estimating results of a complex calculation. Look at question 1 on IWB and talk about how to round.
Estimate answers to these problems
19.7 x (9.62 -2.72) | (34.75 ÷ 5.8) x 4.7 |
(18.52 ÷ 38.5)2 | (78.2 ÷7.3)/ (2.32 x 14.52) |
Question 2: Using a given sum to solve similar problems
If 3 x 4 = 12 What else do we know
If 2.3 x 4.5 = 10.35 What else to we know?
From the above sum can we work out
- 2.3 x 45
- 23 x 4.5
- 23 x 45
- 0.23 x 0.45 etc
If 45.6 x 23 = 1048.8. how do we quickly work out 45.6 x 24
Question 3 – Practical Applications of Percentages/Fractions
Question 4 – Substitution and rules of BODAMS.
Question 5 - Function machines using algebra
INPUT......Add 3......MULTIPLY by 2.... Output. One value gives an output 3 times the input, can you find it
What number gives half of its input value
Question 6. Reminder of how to find LCM and HCF of Two or more numbers
Question 7: Percentage Increase
REMEMBER: Difference / Original x 100
Starting weight 5 kg One month later weighed 6.5 kg. What is Percentage Increase?
Question 8. ALGEBRA and BODMAS and Expanding a quadratic (Multiplying two brackets together – lots of examples
PLENARY: Check on confidence now – These two pages completed would give33/66 marks and would give a grade B
