CodeMonkey

Code Monkey learn coding

Students of all ages, how are your coding skills? Why not try the challenges on CodeMonkey? This is a great way to learn to code if you have little experience – and still fun if you do have some coding skills already.

Can you help the monkey get all his bananas? Look at this simple example – challenge#8; click on the image to see this solution. Note that you learn about loops in later challenges.

Code Monley Example
Code Monkey stars
After each challenge is successfully completed, you will receive a number of stars, note the meaning of each. Did you get all the bananas? Did you use what you learned and were you efficient in your coding?

You have the option to return to the challenge return

SACU

Research UK university courses with SACU. The site is useful for students of any subject anywhere however as you can take the Spartan Test to help you find the right course; the test is quick and fun to do – select images which best describe you!

You can use the Research Tools (all free to use) to take the Spartan Test, explore subjects, courses, the UK map and Apprenticeships; You can also look at possible careers. The gallery below will give you an idea of the wealth of information available and different ways to explore it. The site is intuitive to use and very well designed.

Explore Mathematics

There are many sites where you can explore Mathematics beyond your school syllabus – try some of these:

Maths Careers this site, managed and maintained by the Institute of Mathematics and its Applications has extensive information on careers in Mathematics and applications of Mathematics in everyday life. Note the various tabs such as Science and Engineering at the top of the page and pages for various age groups, see 11-14 for example.

Nrich (note you can search for a topic)

Mudd Math Fun Facts

Amazing Number Facts

Magic Squares

STEP – Worked examples

Introduction to university Maths from the University of Bath

Lots more questions!

Perhaps you are revising for end of year exams. If you want some basic practice then David Watkins has an extensive collection of spreadsheets so you can try as many questions as you like on many topics at your chosen difficulty level and then check your answers. The spreadsheets can all be found on his Dynamic maths site.

Search Dynamic Maths

Search Dynamic Maths

Start by searching for the topic you want; let’s suppose you want to look at adding and subtracting directed numbers. Select the down arrow in the search box and select the topic you want; here we need integers. You will then see a selection of Dynamic Worksheets which are all Excel files. If you want to add and subtract integers then choose Integers-01 and download it. Once you have your Excel file you can practise as much as you want as you can generate as many questions as you like.

You will need macros enabled.

Dynamic Maths - Integers

Dynamic Maths – Integers

Note that you have several choices, you can show answers when you are ready to check; you can choose the number and type of questions and so on.

For more sites with lots of questions see this post which includes questions for older students too.

 

Algebraic Fractions

A collection of resources for you to learn and practise algebraic fractions.

For a basic explanation see Mathisfun and note the questions to try at the end of that page.

The University of Hull Mathematics notes seem very clear, in the Algebra section we have clear notes and exercises with answers on Algebraic Fractons. The notes and exercises include adding, subtracting, multiplying and dividing algebraic fractions.

Algebraic manipulation from Just the Maths includes a section (1.5.4) on Algebraic fractions.

The mathcentre has a section on simplifying algebraic fractions. On the subject of algebra generally, the mathcentre has a very useful refresher booklet.

From the Centre for Innovation in Mathematics Teaching see section 10.13 of this chapter on equations for examples and exercises with algebraic fractions. You could check answers to the exercises on Wolfram Alpha. For example :

Calculators & Tools

Calculating FinancesA whole new section.

I thought I would gather together useful sites/tools for checking your work.

This will be kept updated with any new tools I come across that I think will be useful. I will also add relevant notes and examples.

Do explore the various pages;

I have checked all links are working and made some happy discoveries along the way where tools have been improved. There are many calculators here from basic to rather more advanced. I will keep these pages regularly updated.

On Decision Mathematics for example, check the excellent Linear Programming grapher from zweigmedia.com:

Linear Programming Grapher - zweigmedia.com

Linear Programming Grapher – zweigmedia.com

And look at the calculator from zweigmedia for normal distribution probabilities on the Statistics 16+ page, not only are probabilities calculated but a very clear diagram illustrating those probabilities is also provided.

Normal Distribution Calculator - Random Science Tools and Calculators

Normal Distribution Calculator – Random Science Tools and Calculators

The Graphs section has also had a major update with all the Desmos resources gathered together

Desmos Slideshows

I thought it would be useful to put all the Desmos examples in one place. These slideshows show you many examples of Desmos graphs and the syntax you need to create them.

Statistics – WolframAlpha

A new slideshow has been added to the page demonstrating WolframAlpha syntax. WolframAlpha can be very useful for checking for example normal probabilities. Each query as you will see in the slides is illustrated with a diagram. It is always useful to sketch a diagram when solving any normal distribution problems.
