#### Statistics: Binomial Distribution Bundle (3 Lessons)

This is an excellent bundle looking at all the different aspects of the binomial distribution. 1. Investigation and Introduction 2. Solving problems / calculating probabilities 3. Expectation and variance NOTE: Feel free to browse my shop for more excellent free and premium resources and as always please rate and feedback, thank you.

#### Statistics: Binomial Distribution 2 - Solving Problems / Calculating Probabilities (+ worksheet)

This is a whole lesson (18 sides) plus worksheet building on the first fantastic lesson on the topic. It has a starter, learning objectives, keywords, then look at specific examples of questions, with some great teaching slides, built in activities to test and develop understanding, a worksheet with answers and plenary. This comes as one of three lessons on the binomial lesson and 4 if you include using the normal approximation. NOTE: Feel free to visit my shop for many more excellent free and premium resources and as always please rate and feedback, thank you.

#### 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.
