Good luck in your exam tomorrow

Good luck. Tomorrow I plan to come in at the start of the exam and stay working until the end. Make sure you eat breakfast and have spare batteries etc before the exam starts.

Revision Class

I will be at school on Wednesday from 1-3 for those who would like to have some extra tuition ready for their exam next week. I will have a couple of past papers for you to work through and will specifically recap quadratics/function and common question types.

Exams

Those who have not picked up your exams should find them in the back storeroom in your folders. I did not take them home. You are welcome to have them for your tutors and revision.

One week to go

Hi all I will be back on Monday week three See you there!

Finding the rule

Today we looked at findng the rule from tables if you have already identified the relationships type.
Here are the notes. Make sure you make the connections between intercepts and rules as this is the first step to solving.

5 function introduction

Here are the class notes for the indentification of the 5 functions required for the 2CD course. You need to recognise them in table, graph and equation form.

Make sure you are familar with the terminology for the functions, particularly asymptotes and ratios

functions

This is the first instalment on sites to try and look at for functions. I will put the class notes up on the blog by Wednesday when we have finished them.

Comsider having a look at the khan learning academy. It is a series of videos that J and S have been watching to get another point of view.
http://www.khanacademy.org/math/algebra/#algebra-functions

this website is good for exploring and investigating the effects for transformations. It is American so reciprocal graphs are rational functions

look for yout tube clips as well.

Indices

here are the class notes on indices, consider learning the squares, cubes, powers of 2 & 3 as this helps later when solving equations in the non calculator papers

Completing the square to solve quadratics

In response to whether completing the square is a good way to solve quadratics is a matter of personal choice. It is a valid way of doing it. You must remember that square root of a number has 2 solutions (the positive and negative result.

example (x-2)^2 -9 = 0
               (x-2)^2 = 9
solve x-2 = 3 or -3
therefore x = 5 or -1 these are the roots of the equation as well when written as coordinates.

Do you need Help?

If anyone needs help with particular questions make a comment and I will check each evening and respond as a blog

Good Luck in your exams

Good luck and study hard this coming week. Start with the topics that made the most sense and then work on the ones that didn't. Post comments and questions and I'll try and get back within 24hours

Bivariate Data

Good luck on the test tomorrow!
here are the bivariate notes from today. Remember that this topic is about reading tables carefully looking for units that may be in text above. the bivariate information requires you to be familar with the terminology and use it in justifying answers. Correlation, regression line are key concepts. The book SUPERCRUNCHERS is a great read for context in this topic!

Quadratic Solving

After the poor results from the last test the blog will have some practice questions and notes covering quadratics, functions and algebra manipulation strategies.
here are some links to practise factorising.
BBC bitesize activity
changing formulae notes
General algebra skills
ixl practise (do all algebra topics)

Attached are the notes from solving quadratics

Finance

Start collecting information on credit cards, investments and loans
Key words are depreciation and inflation. You need to be able to calculate percentage increase/decrease in single calculations by the end of this chapter.

Try this game for something different
percentage change game

other ideas include watching the video on spreadsheets from the classpad website and the finance sections as this is one of the tasks you be set for homework.

Good luck with the test on Tuesday.
You need to study networks (max flow and minimum connect), Functions, number skills (rounding scientific notations etc). Questions need to be ready for Monday

Week 9, Chapter 6 'Quadratic Equations'

In class we have been doing Quadratic Functions as some of this is revision from 2A/B it is getting into more context we're exposed to more. I have found this reasonably hard, as while others have too. We also received our investigation marks back, with everyone passing the course so far. Our next test will be Term 2 Week 1 and it is advised that this will be the hardest test so far.

Investigation score i received 88%

P.S Study hard!!

Co-ordinate Geometry

Here is a video I found on co-ordinate geometry. I found it very useful.

Co-ordinate Geometry

Here are some links to various websites that might help with co-ordinate geometry.

try and find some more examples

Sequence Notation Video

Use this guys for your EPW it will help you understand. Also when you see website you will see more videos relating to same topic.

Sequence Notation

Well done to those who have started their EPW due Monday. here are some summary notes about sequence notation that might be useful.

Consider what skills from last year you need to write the general rules.

Week 7 Review

This week has been a bit full on with Coordinate Geometry and Sequence Notation. We also have been handed our EPW for week 7 , which is due Week 8 Monday, also being the date of our Validation. The teacher has gone over the topics above very well and i personally understood and retained 90% of the work. Although most of it was revision to me seeing i learn't some of the topics in 2A/B Function notation was quiet difficult.

Good luck to all in your EPW and Validation.

Week 7: 'Co-ordinate Geometry' Chapter 5

On the 13th of March we started learning about co-ordinate geometry. The teacher also had to revise sequence notation to us. Graphs and gradients were also ways a challenge for me so this area will challenge me more then the course has so far.

Co-ordinate geometry

Watch this link to youtube about co-ordinate geometry.
We start this topic next week. You need to know about linear functions and it would be worth revising finding gradients and intercept in the form y=mx+c

Week 6: 'Numbers' Chapter 4

On the 6th March in 2CD maths we learn't how to do Recurring Decimals, Significant Numbers(S.F), we also completed some examples of these topics and most people in our class got a grasp on the idea. I  myself found it really easy to do. Also to remind myself of these topics a revised(STUDIED) them that night.

Significant figures information

Notes from class

Here are some of the notes from the number lesson this week

Network Reflections

Here is a reflection about the topic on networks completed this week
"Over the past week we have been working on and revising different ways to figure out the maximum flow and then minimum cut of networks, and worked on our knowledge of Prim's algorithms, She told us that next year she'll teach us how to count." MJ

Wk 2 reflections

Here are two weekly reflections

"Last week I decided to stay in 2CD maths stage to give myself a challenge. We learnt how to do sets which is taking me a while to get used to the idea and language of it. this is because it was a new topic and the symbols confused me with their meaning, but towards the end I started to get the hang of it with my friends help" (RR)

"learning about sets for the first time. We learnt about the vocabulary and the symbols. Learning sets was interesting and a relatively easy subject"  (DF)

Tips for the test next week is to know notation and vocabulary

Set Theory

Have a look at this you tube video on set theory.

 

This gives you the first in a series of set theory videos.search the rest and make comment.
