We have below bronze, silver and gold tutorials for Using Similarity in the Relationships unit of National 5 Mathematics. Bronze tutorials are typically unit assessment standard with the silver tutorials providing typical "exam type" questions as examples. If you can manage these you should try our more advanced gold tutorials containing the more unpleasant "exam type" questions. Typically as you work through the modules, the difficulty of the skills increase by one step ensuring smooth progression. Simply click on the video to play it and pause it at the relevant points for you to attempt the questions. Each tutorial has a corresponding worksheet for you to download if additional practice is required. Make sure you have a pen and paper handy! Once you've mastered the skills, why not try the Pastpaper questions at the bottom of the page?

These are the skills that you should already have mastered with BEFORE you begin studying this National 5 module. Do you remember them? If you are unsure, watch the videos and try some questions, it will make learning this new topic so much easier!

• Enlargement and reduction (MTH 317c)        Bronze         Silver         Gold
• Calculating scale factor (MTH 317c)              Bronze         Silver         Gold

You should have encountered basic similarity before in 4th Level Maths and this bronze module takes your through standard National 5 "exam type questions for the enlargement of shapes.

VIDEO 126: Outcome 1 - Similar shapes; enlargement. Grab a pen and your Rigour jotter. Make sure you try all the questions! 

Silver takes you through the 3 processes again only this time for the reduction of shapes.

VIDEO 129: Outcome 1 - Similar shapes; reduction. Grab a pen and your Rigour jotter. Make sure you try all the questions! 

At gold level, we look at similar triangles and more complex "working backwards" questions for area and volume.

VIDEO 132: Outcome 1 - Similar triangles. Grab a pen and your Rigour jotter. Make sure you try all the questions! 

Once you have mastered the skills, why not try the pastpaper questions? Click on each question to play the video. Pause it when prompted to do so and have a go yourself first. When you've finished check the solution. You should aim to complete these questions more than once at various stages throughout the year. If you feel that you need more practice at that particular question go to the practice area suggested in the video...good luck!

You have completed this module - well done! Remember to go back and redo any areas of weakness, that's how we improve. If you are happy with all areas, go back to the main menu and pick another topic to practice!
