Ratio

There are 366 different Starters of The Day, many to choose from. You will find in the left column below some starters on the topic of Ratio. In the right column below are links to related online activities, videos and teacher resources.

A lesson starter does not have to be on the same topic as the main part of the lesson or the topic of the previous lesson. It is often very useful to revise or explore other concepts by using a starter based on a totally different area of Mathematics.

Main Page

Ratio Starters:

Aunty Dotty: A real life situation requiring the division an amount of money according to a given ratio.

Hole in One: If six girls can plant 90 trees in a day. How many trees can ten girls plant in a day? The unitary method.

Missing Square Puzzle: The missing square puzzle is an optical illusion used to help students reason about geometrical figures.

What are they?: A starter about sums, products, differences, ratios, square and prime numbers.

Comment recorded on the 14 September 'Starter of the Day' page by Trish Bailey, Kingstone School:

"This is a great memory aid which could be used for formulae or key facts etc - in any subject area. The PICTURE is such an aid to remembering where each number or group of numbers is - my pupils love it!
Thanks"

Comment recorded on the 2 April 'Starter of the Day' page by Mrs Wilshaw, Dunsten Collage,Essex:

"This website was brilliant. My class and I really enjoy doing the activites."

Comment recorded on the 5 April 'Starter of the Day' page by Mr Stoner, St George's College of Technology:

"This resource has made a great deal of difference to the standard of starters for all of our lessons. Thank you for being so creative and imaginative."

Comment recorded on the 26 March 'Starter of the Day' page by Julie Reakes, The English College, Dubai:

"It's great to have a starter that's timed and focuses the attention of everyone fully. I told them in advance I would do 10 then record their percentages."

Comment recorded on the 1 May 'Starter of the Day' page by Phil Anthony, Head of Maths, Stourport High School:

"What a brilliant website. We have just started to use the 'starter-of-the-day' in our yr9 lessons to try them out before we change from a high school to a secondary school in September. This is one of the best resources on-line we have found. The kids and staff love it. Well done an thank you very much for making my maths lessons more interesting and fun."

Comment recorded on the 2 May 'Starter of the Day' page by Angela Lowry, :

"I think these are great! So useful and handy, the children love them.
Could we have some on angles too please?"

Comment recorded on the 9 May 'Starter of the Day' page by Liz, Kuwait:

"I would like to thank you for the excellent resources which I used every day. My students would often turn up early to tackle the starter of the day as there were stamps for the first 5 finishers. We also had a lot of fun with the fun maths. All in all your resources provoked discussion and the students had a lot of fun."

Comment recorded on the 6 May 'Starter of the Day' page by Natalie, London:

"I am thankful for providing such wonderful starters. They are of immence help and the students enjoy them very much. These starters have saved my time and have made my lessons enjoyable."

Comment recorded on the 7 December 'Starter of the Day' page by Cathryn Aldridge, Pells Primary:

"I use Starter of the Day as a registration and warm-up activity for my Year 6 class. The range of questioning provided is excellent as are some of the images.
I rate this site as a 5!"

Comment recorded on the 19 June 'Starter of the Day' page by Nikki Jordan, Braunton School, Devon:

"Excellent. Thank you very much for a fabulous set of starters. I use the 'weekenders' if the daily ones are not quite what I want. Brilliant and much appreciated."

Notes:

A ratio is a relationship between two numbers of the same kind. In layman's terms a ratio represents, simply, for every amount of one thing, how much there is of another thing.

This topic presents a number if different ways pupils can represent ratios and apply their meaning to problem solving situations.

Ratio Teacher Resources:

Dividing in a Ratio: A slide presentation showing how to divide a quantity in a given ratio

Ratio Activities:

Direct and Inverse Proportion: A self-marking exercise in solving direct and inverse variation problems.

Map Scales: Test your understanding of map scales expressed as ratios with this self marking quiz.

Pattern Clues: An interactive activity challenging you to reproduce a pattern of coloured squares according to given clues.

Ratio: A self marking exercise on using ratio notation, reducing a ratio to its simplest form and dividing a given quantity into a number of parts in proportion to a given ratio.

Ratio Clues: Arrange the ratio clues in the clouds in a logical order to work out the values of the twelve letters.

Recipe Ratios: Learn the mathematics required to adapt recipes to serve a different number of people.

Scale Drawings: Measure line segments and angles in geometric figures, including interpreting scale drawings.

Similar Shapes: Questions about the scale factors of lengths, areas and volumes of similar shapes.

Unitary Method: Ten questions which can be solved using the unitary method.

Finally there is Topic Test, a set of 10 randomly chosen, multiple choice questions suggested by people from around the world.

Alternatively, for the more advanced student, there is an ever-growing collection of Exam-Style Questions with worked solutions on the topic of Ratio.
