Year 9 Revision - 9A1

Right then Maths Genius's - Here are some things to help your revision along some more.
From Tuesday's lesson here are the topics you will need to know for the test.

Here are the questions from the lesson so if you didn't finish you can work them out.

and here are some more test based questions with a Mark Scheme so you can see how you did.

REMEMBER - Don't keep revising what you are good at.  Remember which topics your weaknesses are in and revise those first!

Factorising Quadratics

Year 9 please find your factorising homework here

The questions on factorising using the quadratic formula are here. and these are your answers.

Reflections

Here is your Reflections homework at last.

I've attached a different file here, as the other one was corrupted.

Please copy and complete in your books over Christmas.

Keep an eye on the blog for Revision materials.  Tests will be in the 2nd week back after Christmas.  Check the Year 9 Scheme of Work post for a list of all you need to revise.

Times-tables fortnight

Coming up over the next 2 weeks we have our times-tables fortnight.  Here are the cards you can use to help you to remember your tables.
2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, 11x, 12x 
Remember to carry your cards with you and get them signed between now and Christmas.

Year 9 Medium Term Autumn 1

Year 9 - revision time

If you are taking the levels 5-8 paper your test this week will be on:

• Fractions/Decimals/Percentages
• fraction of amount
• operations with fractions
• % increase/decrease
• reverse %
• using multipliers
• operations with decimals

• Area/Perimeter/Volume
• Area of Circles, Trapeziums, Triangles
• Volume and Surface Area of Prisms (inc. cylinders)
• Perimeter and Circumference of 2D shapes
• Nets of 3D shapes

•  Sequences and Formulae
• Find nth term of linear and quadratic formulae
• Construct and use equations in context from sentences.

• Measures
• Convert between measures
• Use compound measures to determine speed/distance/time etc.

Make sure you especially revise all the areas you struggle with NOT just the ones you know you can do!!

Compound Measures

A Compound Measure is made up of 2 or more other measures e.g Speed or Density.

Here you will find slides on working out compound measures.  Click HERE to Try some questions for yourself.
Some further Speed, Distance and Time questions can be found on this worksheet.

Volume

Please find your volume homework here.

Properties of Quadrilaterials

Find the properties of all the quadrilaterals you will ever need here.

Metric and Imperial measures

Here is a powerpoint to help you understand converting between measures.  Make sure you understand how to convert between different measures.
Here is a conversion list and some exercises to try.
