# Calculating Probabilities from Two-Way Tables

Students learn how to calculate a probability from a two-way table.  As learning progresses students learn how to create a a two-way table from a written description and consider how the sample size changes for specific groups.

The start of the lesson recaps reading data presented in a two-way table.  The end of the lesson is used to assess the progress made agains the differentiated learning objectives through an exam style questions.

##### Differentiated Learning Objectives
• All students should be able to complete a two-way table.
• Most students should be able to use two-way tables to calculate theoretical probabilities.
• Some students should be able to understand the change in sample size for different criteria.

#### Teaching Mathematics for a Growth Mindset

Inspiring students to enjoy maths and feel the success that comes with attempting a difficult challenge is why I teach.  The feeling of success is addictive.  The more students experience it the more they want it and the further out of their comfort zone they are willing to go to get more of it.  Teaching […]

#### Equation of Straight Line Graphs

To find the equation of straight line graphs students need to calculate the gradient using two pairs of coordinates and the intercept which is the y value of where it crosses the vertical axis.  Examiner’s reports of past exam questions show students are more able to find the intercept of a straight line than they […]

#### Arithmetic and Geometric Sequences

Students learn how to generate and describe arithmetic and geometric sequences on a  position-to-term basis.  Learning progresses from plotting and reading coordinates in the first quadrant to describing geometric sequences using the nth term. This unit takes place in Term 4 of Year 10 and is followed by the equations of straight line graphs. Arithmetic […]
