Monty Hall Problem

Monty Hall Problem

A look at the Monty Hall problem in an easy-to-understand way. Great introduction to probability suitable for KS3 up to A-Level. Three doors. Behind one is a car, behind the other two are goats. You pick a door, a goat is then revealed behind another door by the host. You have the option to switch to the remaining closed door or stick. What do/should you do?

Edexcel S1 Revision clock

Edexcel S1 Revision clock

This is a revision activity for Edexcel S1 based on the ideas shared on Jo Morgan's brilliant website http://www.resourceaholic.com/. This was originally shared here http://justmaths.co.uk/2015/10/18/keeping-time/. This activity could be used to help improve students' timing by giving them 5 minutes for each of the 12 questions, to improve memory, or simply to produce a visual revision resource. Each student should be given an A3 copy of the clock with a set of questions. Answers are provided.

Statistics: (S1) Coding or making the variance or mean easier (+ rule sheet)

Statistics: (S1) Coding or making the variance or mean easier (+ rule sheet)

This is a teaching resource to help pupils understand coding and the basics of linear adjustments/combinations and how to calculate back and forward from the original data to the coded data. It comes with a good starter, a look at re-arranging and then why coding is used and how it is used. Links to past exam questions, however, it does not come with lots of questions as at that point of practice, I use our S1 textbook. Also a rule sheet handout!

Statistics: (S2) Linear Adjustments / Combinations  - 4 Lessons + Handout

Statistics: (S2) Linear Adjustments / Combinations - 4 Lessons + Handout

This teaching PowerPoint contains 4 whole lessons! Lesson 1: Linear adjustment of random variables Lesson 2: Linear Combinations of random variables Lesson 3: Linear combinations for normal distributions Lesson 4: Linear combinations for Poisson distributions + Rule sheet HANDOUT These lessons are very structured, with clear lesson objectives, clear examples and small activities to build understanding of what linear adjustments/combinations do and why the rules are the way they are. The lessons do link to a textbook that I use, however, for copyright reasons I can not publish these exercises, but this is easily substituted for another textbook that you use to accompany your course. I have found these PowerPoints to be very effective in teaching this topic. NOTE: Feel free to browse my shop for more free and premium resources and as always please rate and feedback, thanks.

Statistics: Expectation and variance for a binomial distribution PPT

Statistics: Expectation and variance for a binomial distribution PPT

This is a PowerPoint (lesson two) to go with the previous PowerPoint on expectation and variance to build on looking at how to link the variance and expectation for binomial distributions. The PowerPoint mainly looks at building on understanding and why the formula's work and how to use it.

Statistics: Expectation and varience of discrete random variables

Statistics: Expectation and varience of discrete random variables

This is a whole lesson, which includes teaching slides, as well as activities for ALL pupils to engage with the process of going from a probability distribution to learning why and how to find the expectation and variance. NOTE: Feel free to browse my shop for more excellent free and premium resources and as always please rate and feedback, thanks.
