Welcome to Mathsmadeeasy.
We have a BIG challenge with Maths and Science education in the UK. Internationally we are 27th and 16th respectively in league tables and domestically over 41% of our students failed to achieve maths grade C in 2011. Whilst our competitors have raced ahead we have, in the words of the OECD’s Director of Education, ‘stagnated’.
As they say 'every little helps' and the aim of Mathsmadeeasy is to improve maths achievement in the UK through written resources and coaching.
KS3 .. to .. A-level mathematics and science tuition
An outline of our teaching style, what and where we teach and testimonials.
...and how we are helping trainee teachers pass their qts numeracy test.
Key stage 1 & 2
Key learning at school from age 5 to 11 years
SATS (Standard Assessment Tests) tests are given at the end of year 2 and year 6. They are used to show your child's progress compared with other children born in the same month. For KS1, each child is assessed in reading, writing (including spelling and handwriting), maths (including number, shape, space and measurement) and science. For KS2 tests cover the three core subjects, English, Maths and Science.
Key stage 3
Key learning at school from age 12 to 14 years
Years 7 to year 9 span the period called key stage 3, culminating in the Maths, English and Science SATs tests.
By the age of 14, most children are expected to achieve level 5. These exams are often used to decide which GSCE set your child will be in.
General Certificate of Secondary Education, usually taken from ages 14 - 16 years.
Start in year 10, a two year GCSE course can be either modular (exams over two years) or linear (exams at the end). Two exam papers are taken at Foundation (achieving up to grade C) or Higher tiers (up to A*). Level 2 Key Skills = A*-C and Level 1 = D-G
Advanced Subsidiary and A2 levels
AS Mathematics or Physics in year 12, has three modules usually examined in January or June. A2 Maths or Physics, a further three modules in year 13, completes the A-level course. AS and A2 are both 50% of the full A Level.
The information provided is based on the OCR board, but will be applicable to other exam boards.

Module Chemistry C1 (OCR B711): Carbon Chemistry – Revision topics
Year 10 GCSE Chemistry science examined from Jan 2012
GCSE Science Chemistry Gateway Core has been revised from 2011.
FUNDAMENTAL CHEMICAL CONCEPTS
Write word equations given the reactants and products.
Recall the formula of:
carbon dioxide and carbon monoxide
oxygen and water.
(HL) sulphuric acid
Covalent and Ionic bonds
an ionic bond is the attraction between positive ion and a negative ion.
a covalent bond is a shared pair of electrons.
Explain how an ionic bond is formed.
Explain how a covalent bond is formed.
positive ions are formed when atoms lose electrons negative ions are formed when atoms gain electrons
Compound or element?
Work out the number of elements in a compound given its formula.
Work out the number and type of atoms in a formula with no brackets.
Work out if a particle is an atom, molecule or ion given its formula.
Atoms contain smaller particles one of which is a negative electron
C1A MAKING CRUDE OIL USEFUL
What are fossil fuels and how are they used?
How are fossil fuels extracted and what problems do we face as we use them?
Meaning of non-renewable
What can be made from crude oil and how can the different chemicals be separated out from crude oil.
Fractional distillation works because of differences in boiling points. LPG, petrol, diesel, parafin, heating oil, fuel oils and bitumen are fractions obtained from crude oil.
LPG contains propane and butane gases
crude oil is heated
the fractionating column is colder at the top and hotter at the bottom
fractions with low boiling points 'exit' from the top, with high boiling points 'exit' at the
needs a catalyst and a high temperature
converts large hydrocarbon molecules into smaller ones that are more useful
petrol from liquid paraffin.
converts large alkane molecules into smaller
alkane and alkene molecules
alkene molecules can be used to make polymers.
polymerisation (HT)how do intermolecular forces lead to the difference in boiling points.
(HT) which fractions are most useful/most in demand as a lead in to the next lesson on cracking
How oil companies change the amount of product in each fraction to meet the demands of society.
Use of the different products particularly ethene.
(HL) why each fraction is not necessarily as useful and why petrol is so useful.
C1B USING CARBON FUEL
Which properties of a fuel make it suitable for its use?
Energy value, availability, storage ,cost, toxicity, pollution eg acid rain, greenhouse effect, ease of use
The complete and incomplete combustion of a fossil fuel. The pros and cons of each.
Bunsen Flame - blue, yellow flame
(HL) balance an unbalanced symbol using 2, 1.5 and 1 in front of the oxygen to show how reducing the oxygen can change the products
Incomplete combustion of a hydrocarbon fuel makes carbon monoxide, carbon (soot) and water.
Carbon monoxide is a poisonous gas.
Write word equations to show the incomplete combustion of a hydrocarbon fuel given the reactants and products. (HT - balance it)
C1C CLEAN AIR
The present day composition of the atmosphere and how this composition came about from the volcanic gases released into the original atmosphere.
Air =21% O, 78% N, H
2O,CO 2 Photosynthesis, respiration combustion affect the level of CO
2, O in air. O, N, CO 2 levels in present day atmosphere are constant.
Volcanoes → atmosphere rich in water and C02
condensed water vapour form oceans
Dissolve carbon dioxide in ocean
Increase of N - due to its lack of reactivity
Development of plants
Increase in oxygen levels due to photosynthesis Atmospheric pollutants
Understand where atmospheric pollutants originate from and why they are dangerous.
carbon monoxide - a poisonous gas formed by incomplete combustion of petrol or diesel in car engines
oxides of nitrogen make photochemical smog and acid rain and are formed in the internal combustion engine
sulphur dioxide - causes acid rain that will kill plants, erode stonework and corrode metals and is formed when sulfur impurities in fossil fuels burn.
catalytic converter removes carbon monoxide from car exhaust.
(HL) know the balanced symbol equation for a catalytic converter
2CO + 2NO → N
2 + 2CO 2
C1D MAKING POLYMER
What a hydrocarbon is, the structures of alkanes = saturated hydrocarbons.
(HL) use the molymods to show that the structure of the hydrocarbons is not in two dimensions but is actually in 3D.
Many polymers are non-biodegradable and so will not decay or decompose by bacterial action.
Waste polymers can be disposed of: use of land-fill sites, burning of waste polymers, recycling.
Structures of alkenes =
unsaturated hydrocarbons. How addition polymers are made from monomers, Understand the structure of polymers and how to name them.
Large molecules, called polymers are made when many small molecules, called monomers, join together in a polymerisation reaction.
Alkenes have a double covalent bond(s) between carbon atoms. Double bonds involve two shared pairs of electrons The double bond is shown by the reaction with bromine water orange to decolourised.
Draw the displayed formula of an addition polymer given the displayed formula of its monomer.
C1E DESIGNER POLYMERS
Understand the properties of polymers that allow them to be used for specific purposes.
Nylon is tough, lightweight, keeps water out and keeps uv light out but does not let water vapour through it which means that sweat condenses
Gore-tex® has all of the properties of nylon but is also breathable.
Be aware of the problems posed by plastics especially in their disposal: non-biodegradable
Nylon laminated with ptfe / polyurethane membrane
Holes in membrane are too small for water to pass through but are big enough for water vapour to pass through
Membrane is too fragile on its own and so is combined with nylon
Plastics are held together by strong covalent bonds.
Relate the properties of plastics to simple models of their structure
C1F COOKING AND FOOD ADDITIVES
Understand the changes that occur in foods when they are cooked and that some foods have additives to enhance taste/colour etc.
A chemical change (cooking) takes place if:
There is a new substance made
The process is irreversible
An energy change takes place.
Antioxidants stop foods from reacting with oxygen
Food colours give food an improved colour
Flavour enhancers improve the flavour of a food
Emulsiers help oil and water to mix and not separate.
Hydrophobic and hydrophilic nature of emulsifying agents
Understand the action of heat on baking powder.
baking powder helps make cakes rise.
2 turns lime water cloudy. egg or meat changes when cooked - shape of protein molecules changed.
Potato is easier to digest if it is cooked
Word equation for the decomposition of sodium hydrogencarbonate

C1H PAINTS AND PIGMENTS
Paints are colloids and the different parts of a paint.
What happens when paint dry
The properties and some uses of thermochromic paints
The properties and some uses of phosphorescent paints
Describe how paints dry emulsion paints = water based paints that dry when the water evaporates.
oil paints dry when the solvent evaporates, the oil is oxidised by oxygen
Ingredients of a paint:
solvent thins the paint and makes it easier to spread
binding medium sticks the pigment in the paint to the surface
Pigment is the substance that gives the paint its colour.
oil paints: have the pigment dispersed in an oil
paint = colloid where the particles are dispersed with particles of a liquid but are not dissolved.
