### Long Multiplication

This site on

Long Multiplication goes through three ways traditional, Napier and my favourite - the grid method.

### Week 2 FDP ( Fractions, Decimals, Percentages)

1.Compare fractions, decimals, percentages Match the pairs (fun way of finding/remembering equivalences)

2.Match decimals and % Match the pairs (Skillswise) - decimals and % only. Use this if 1 was too hard.

3. Compare Fractions and decimals Match the pairs (Skillswise) - fractions and decimals only. Use this if 1 was too hard.

### Ratio, Proportion, Scale

There are usually 2 if not 3 questions on both Level 1 and Level 2 Numeracy papers; this is then a crucial skill.

1. Understand that ratios can be simplified in the same way as fractions.

2. Use ratios directly to find 'parts' in a drink, a mix of cement etc.

3. Use 'recipes' or 'menus' to convert amounts given for 4 people to 6, 8, etc.

4. To understand that the scale on a map is a ratio - to convert from the map to real life and backwards.

EXAMPLES

1. A worksheet showing how to cancel fractions will be given.

2. Ratio is given

a. Draw a bottle - label the two different components

You have

1 part of squash

3 parts of water

________________

4 parts altogether

b. Find out what each part is worth

Divide 2 litres by 4

Change 2 litres into 2000 millilitres

c. The answer is 1 part is worth 2000/4 = 500ml

d. Draw in your diagram squash =500ml (1 part), water =1500ml (3 parts)

The Skillwise worksheets help.
