It has been awhile since the last update. We are now back to term 2 and before I proceed, here are a few updates and feedback of term 1.
Positives:
- Many of you did well for paper 1 and scored 30 over upon 40. Keep that up. Continue doing well for your paper 1.
- I was glad to see a huge number of you turning up for the extra morning lesson :)
Can be improved:
- Paper 2 is definitely a section many of you need to improve on. More practice is needed. Focus also on your 'Get me thinking' assessment book.
- Concentration and 100% consistent effort. This aspect can be much better during this term.
Geometry is also an area I find that you guys have not been able to excel in. Topics like area of square and perimeter of square and angles are past year topics you need to go back and revise again.
Fraction 2:
- Read the problem sums carefully to find out what fraction is required.
- Fraction out of a fraction --> fraction x fraction
- Fraction out of a whole number --> fraction x whole number
- Whole number out of a whole number --> whole number 1 divide by whole number 2
When we multiply fractions:
- Method 1:
- Multiply numerator 1 and numerator 2 together
- followed by denominator 1 x denominator 2
- 2/3 x 3/4 = (2x3)/(3x4) = 6/12
- Method 2:
- Cross multiplying
- Look at the numbers diagonal to each other (this will form a X)
- Find the two numbers' highest common multiple (if any) to simplify the numbers further
- Example: 3/4 x 4/6 (numerator 1 is 3. denominator 2 is 6. Both these numbers' highest common multiple is 3 so you can divide both numbers by 3) (Numerator 2 is 4 and denominator 1 is 4. Both these numbers' highest common multiple is 4 so I can divide both numbers by 4).
- You will end up with the answer of 1/2
- Cross multiply is a good way to simplify your answer.
- Method 3:
- Up-down simplification
- Look at both sets of fractions first.
- You can simplify the fractions first.
- 4/12 x 2/6
- 4/12 can be simplified into 1/3
- 2/6 can be simplified into 1/3
- so 4/12 x 2/6 = 1/3 x 1/3 = 1/9
Topics to be tested for SA1:
- All P1 - P4 work
- Whole numbers 1 and 2
- Fractions 1 and 2
- Ratio (Up to Word Problems 1)
Study hard. :)
Sincerely,
Mr Nelson Ong
