## Pie Chart Free Resources up to Higher GCSE Maths

4 Mar

A quick blog to share free set of pie chart resources, require no-prep printable downloads, that we produced when NumberLoving joined up with LittleStreams in collaboration.

The worksheets produced by Littlestreams help introduce how to calculate angles in order to construct Pie Charts. Once pupils are able to construct, you can move them into completing the NumberLoving Treasure Hunt. This requires pupils to interpret pie charts; finding amounts from pie chart sectors and includes questions similar to those included in Higher EdExcel and AQA GCSE Maths papers.

LittleStreams drawing pie charts worksheets and check out LittleStreams website for more great resources http://www.littlestreams.co.uk

## Maths Teacher Hack #1 Protractors

20 Feb

Just a quick post to share a Maths Teacher hack for protractors!

Lots of pupils don’t own protractors and so very often I found setting homework that included angles particularly GCSE Maths exam papers that most often include bearings/pie chart to be completed at home difficult. So our hack is to print or photocopy protractors on to tracing paper or if you have it hidden in the depth of the stock cupboard, print onto OHP (Overhead projector transparencies)!

You will need A4 tracing paper and patience with your photocopier, even better ask your reprographics department to do it. Warning when photocopying onto tracing paper the photocopier might not like it too much and chew up some of the pages, it’s best to feed one page at a time. Even better if you have any OHP (Overhead projector) transparencies, print onto these.

Once printed you can then give each pupil a tracing paper protractor to use at home without breaking the budget.

We would love to hear your Math Hack ideas! Get in touch via @numberloving or NumberLoving’s Facebook page!

## Instant Graphs

22 Apr

This post is in addition to creating instant bar charts and pictograms using Post-It notes check out the previous post. Post-it notes are great for collecting information and instantly organising that data into a bar chart or pictogram to find the mode, median and range (if applicable).

Pie charts demonstrate proportions of amounts or a population, to ensure pupils understand this it is vital that they observe some basic proportions represented in pie charts. For example half choose red, a quarter blue and a quarter green.

I always introduce pie charts in this way using pie chart wheels. Pie chart wheels are easy to make. The Instant Pie Chart Template  can be downloaded  with intructions.

Print the pie chart template on four different colours, cut out and then secure the wheels  in place using a pin and piece of card at the back.

Pupils adjust the colours by spinning to represent the results in the Power Point. Then ask pupils to give their own results that could be represented, or not if only  four colours are available.

I always ensure I have red, amber and green in my pie chart wheels as they then double up as an assessment for learning indicator. Pupils display red when they require help, amber when they feeling more confident and green when they are confident and need more of a challenge.

Tallies and Pictograms

Another of my favourite data handling activities is to use music when reminding young year 7 pupils of how to tally. Pick a top ten hit with a repetitive song, as the song plays pupils have to tally the number of times the word is said!

Try it with Cheryl Cole’s “you have to fight for this love” and you have yourself a real challenge. Discussions can then be held about the modal word.

Check out our post on using post-its for instant pictograms on the classroom windows!

## Take a bet…

10 May

Clearly gambling is not something which we should be promoting in Maths, but allowing students the opportunity to gamble opens up the chance to discuss the moral, social and financial implications in a real way. When teaching probability as an end of unit project (in pairs) I ask students to create a game, this is an idea which I adapted from this resource on the TES.  I usually start the lesson by giving an example of a game for them to think about – powerpoint here. Then they have to design their own and make sure the odds are in their favour, they have to work out the probability of winning and losing, think about pricing and prizes and from this work out their expected profit if 10 or 100 people play. This can be easily differentiated through outcome and I have done it with low ability year 7 up to top set year 9 by just adapting the success criteria.

Once they have had a lesson to design their game, make any resources and do all the maths you need to get your hands on some plastic money. Each team gets £10 (their games should cost between 0-£2 to play) and the students set up their games like a fair, they have the opportunity to go around playing one another’s games. Once ten people have played their game they should ‘shut down’ their stall. After this, get students to count their money and see whether they made the expected profit they calculated the previous lesson. You can then have a great discussion about why they didn’t make their expected profit (experiments differ from theory) and whether they still have their original £10 and how this relates to gambling in real life – e.g. the house always wins!

This is a fun project but also a great opportunity to assess and explore lots of elements of probability. If you like this idea you may also like this resource on the TES which is brilliant and includes several games for students to investigate before making their own.

## Puppets go the distance with speed & time

2 Mar

When teaching speed, distance, time graphs your pupils understanding of the graph can be demonstrated by asking them to create a story with the puppets to match a given distance time graph. Easily differentiated by giving pupils different graphs and different conditions e.g. one group must comment on the speed at some point in their story and another include the time spent in each location.

A pack of ten animal finger puppets, and ten people finger puppets are available from ikea (here and here) for £3.99 a pack. There are many hand puppets on line and depending on your budget and your favourite characters the sky is the limit.

Alternatively you may wish to give pupils the story and ask them to draw out the distance time graph. In this video below ask pupils to draw the distance time graph for George’s outing on his bike. This video is particularly good for challenging the misconception that the steepness of the graph represents travelling up hill.

Off course there are many clips on you tube that you can choose to suit your audience.

This football distance time graph online activity uses football video clips and joins this activity with multiple choice questions. This is great for any age but in particular older students. Some of the clips are dated, alternatively start a real debate and use clips from recent matches. As the clips play you can ask the pupils to draw the distance time graph on mini white boards or present them with a choice of three graphs. It is handy to choose a clip in which the player turns around and travels back the way they came.

Also take a look at this standards unit, available through the Stem Centre website here. I really like the idea of matching the graphs to the different descriptions. For a complete lesson plan and resources check out this resource from sbinning available on the TES. This has been adapted from another resource, giving questions about the graphs.

Hope you enjoy the ideas here! Thank you to all our readers, we welcome all feedback. Get in touch @numberloving and check out our free and premium resources in our TES NumberLoving Store.

## Do or Die with dice!

31 Jan

Essential classroom equipment; a set of dice, and ideally large sponge die. They’re in the store cupboard they just need digging out.

Donkey Derby

Or better known as a horse race, in my classroom it is called Derby’s Donkey Derby! Pupils bet a donkey numbered from 1-12. A donkey moves when it’s number is rolled from two dice added together. The first donkey to cross the line wins.

This horse race notebook was contributed to TES resources by Moog, it includes interactive dice.

Nasty

Simple concept of place value. Teams play against each other to get the highest number, or the highest even number etc. When the die is rolled the team decides whether to keep it or give it away. By keeping it they can place the digit into either units, tens, or hundreds unit. By giving it away to another team they decide which column the other team has to place it.

I use this Nasty template simple grid to keep track of each team.

A quick starter, engages pupils immediately. Display six questions on the board as pupils enter they roll the die and answer the corresponding question. Of course even better if you can have two differentiated sets of questions amber (entry) and green (more challenging).

Pupil selector

When working in groups it is important that all pupils know what they’re doing and understand the work. To keep pupils on their toes avoid the hands up situation and introduce a no hands up rule. This ensures the conversation is flowing as pupils coach each other, roll the die to select the person from each group to feedback, explain or answer a question.

Make 24

Roll the die to get 3 or 4 numbers, pupils must then use these numbers and any operations to make the number 24. If you have enough die, pupils can set their own personal challenge.

Probability Experiment

Conduct a simple experiment, roll a die and record the result in a tally chart. Spice it up by introducing a ten or 12 sided die.

Die-Multiply

A game for two players, each with a die. They roll simultaneously, the first player to call out the multiplication result of the two numbers wins. Can be powers for calculator use, or addition for low KS3 classes. Pupils keep a track by tally chart of how many games they win, the person that wins the most in a 5minute slot is deemed champion.

Add a bit of fun with these giant foam dice available from most suppliers and from Bright Ideas website.

## Rock, Paper, Scissors and Tree Diagrams

26 Jan

This classic game is a great idea from my colleague Lee Gould, to use when introducing tree diagrams.

Pupils play the game in pairs 30 times. Each game is recorded in a simple tally chart, noting if player A wins, player B wins or a draw. Pupils can then look at the relative frequency from their results as well as the whole class results. You can then have discussion about theoretical probability, expectancy and relative frequency.

The tree diagram includes two events; player a’s three options and player b’s three options as independent events. The resultant outcomes are either A wins, B wins or draw. Here you can re-iterate the Or & And rules, as well as recap how to deal with fractions.

Rules of the game; I use this picture to remind pupils of which beats which! Yes unfortunately not all my pupils on one class knew the rules!

Where as avid watchers of Friends sitcom asked “Miss, is Fire allowed? It beats everything but water baloon”.

Resources; Probability Tree Diagrams Here is the power point kindly shared by my colleague Lee Gould, (authored by CBillet) to collect the results and put them into a simple independent tree diagram.

Just for fun; Check out this online game where you play against the computer.

If you use this in class, take a picture and post on twitter @numberloving we’d love to see our ideas in action. Get in touch @numberloving and visit our TES NumberLoving store for free and premium resources!!
