Venn Diagram (WHOLE LESSON)

Venn Diagram (WHOLE LESSON)

A power point to help pupils to get to grips with drawing, interpreting and using Venn diagrams to calculate probabilities. This lesson also contains a worksheet with a range of different questions that could be asked in an exam but also an extension task to show pupils the types of exam questions that can be asked. The answers for the worksheet is on the PPT and the mark scheme for the extension is also attached.

Teach in 20 Probability trees

Teach in 20 Probability trees

This started as a teaching prompt to prepare my year 10 set 2 for a end of year mock and it was based on topics we hadn't studied yet. I found I could teach them the content and go through an example and then get them try a question in about 20 minutes - that is 3 new topics in a 60 minute lesson. I printed the PowerPoints as handouts and got the students to work on them. You can of course use them as you see fit. Feedback would be much appreciated! Enjoy :)

Conditional Probability

Conditional Probability

This lesson is aimed at the higher level student. It is designed to be taught after the tree diagram lesson. Probably late into year 10 or early year 11. The worked examples demonstrate how the tree diagram can be used to answer some questions, but also demonstrates another quicker method of dealing with repeated events.

Probability - Sample Space Diagrams (same as new style 1-9 GCSE AQA questions)

Probability - Sample Space Diagrams (same as new style 1-9 GCSE AQA questions)

This resource is perfect if you want a lesson on using sample space digrams to answer probability questions. It has been designed to reflect the NEW STYLE GCSE (AQA) questions on this topic - i.e. two spinners are spun and you have to add them / work out the difference, before answering a probability question. There are two slides with examples that the teacher can use to go through with pupils. There are 4 main questions and two extention questions on the powerpoint and worksheet (ready to be printed!). This has been tried and tested with a set 3 class (target grades 4 and 5) and has worked perfectly.

End of Year Maths Project KS3 - Theme Park & Fairground

End of Year Maths Project KS3 - Theme Park & Fairground

Perfect for ending the year! Whole unit of work for final week or fortnight of teaching. Engaging and rich tasks allow students to develop problem solving skills while having fun! The slides clearing follow the order of the booklet. Session one gets students jooked before looking at budgeting and plans and elevations in session two. Session three and four student begin to design their own theme park plan. Session 5 introduces the second part of the project - creating their own fairground game for the entrance of their theme park. In session two students can create these games and test them, finding out probabilities and using questionnaires to further improve their designs and creations. This has been used successfully with low ability students in year 7 up to high ability students in year 9 - often differentiated through questioning and higher pitched expectations.

Probability Tree Expert Qs

Probability Tree Expert Qs

A set of 7 fairly challenging questions on probability trees, suitable for stretching a class with a good working knowledge of standard probability tree questions. I would use this resource with an able GCSE class, probably asking them to work in small groups. Some of the questions require probability tree type methods, but are best done by taking short cuts rather than drawing complicated trees.

Possibility Space Extension Task

Possibility Space Extension Task

This is for a class that has already done some work on possibility spaces. The first question is consolidation, and involves the probabilities when two spinners are spun. The spinners are then cut into pieces. The students' task for the remaining questions is to reassemble the spinners so as match the probabilities given in each question. Logical thinking is involved, and the task tests the students' deeper understanding of possibility spaces.

Numeracy Who Wants to Be a Millionaire

Numeracy Who Wants to Be a Millionaire

An interactive Who Wants to Be a Millionaire game focused on numeracy questions. The questions near the end get very tricky! They are on the following topics - percentage, area, ratio, factorising, probability, volume, negative numbers, difference of squares, scale factors, angles, sequences, DST I normally do this with pupils writing their letters on mini-whiteboards before the right answer is displayed, and you can also do something with the lifelines if you like.
