Two-way Tables: Lesson 5/13

This Series
This is the fifth in a series of 13 mastery-style lessons on Probability. The others include Venn Diagrams, Frequency Trees, and Probability Trees. All lessons use a pastel-coloured background (which can be changed in ‘master slide view’) and the Verdana font which has been shown to be good for dyslexic students.

These lessons are fully differentiated, and they use whiteboard questions as a scaffolding and assessment for learning method. These whiteboard questions are also particularly useful for reducing students’ maths anxiety by providing them with the correct answer which they then have to pick.

This, as well as the other lessons in this series has a bank of practice questions on the final slide. This is designed to be used in different possible ways. It can be used as a consolidation task after the lesson, as a homework sheet, as an exit ticket (choose a question), or as a cover lesson.

This PowerPoint
The title of the lesson is throughout the PowerPoint. This provides consistency throughout, allows students to catch up if they missed it, and takes late-comers into consideration. The date is also throughout the PowerPoint and updates automatically. This is done so that the students know exactly where it is each lesson, and to make it easier on the class teacher.

The ‘P’ in the bottom right corner is a hyperlink to the slide with the practice questions worksheet on. This can be used at any time before that slide if the teacher feels the students are comfortable with the work and need some practice questions to get on with.

The learning objectives are designed to be in as short sentences as possible to allow students to read them and write them down (if necessary) as quickly as possible. They also use a mixture of simplistic and specialised words to engages students’ thinking about definitions whilst allowing them to access the meaning of the sentences. These objectives are reviewed at the end of the lesson as a self-evaluation of learning technique. Students are awarded ‘brain’ medals depending on how well they feel they have done.

This Lesson
This lesson introduces two-way tables, reading them, and using them in probability. The first question, on this slide, is accessible to all and it a perfect example of a question which has many answers. This allows students to be engaged in thinking without the pressure of getting the answer wrong.

The first two slides are skills-based questions with students being asked to subtract fractions and decimals from 1, an important skill for this lesson.

The Objectives
These are kept as simple as possible and broken down carefully. This is to encourage students to access the material whilst giving them the confidence by achieving something in the lesson.
Bronze. Read two-way tables.
Silver. Fill in two-way tables.
Gold. Use two-way tables to calculate probability.
