# Using Scientific Calculators

Students practise using scientific calculators to solve problems involving brackets, powers and the order of operations.At the start of the lesson students create all the numbers between 10 to 30 using a 'broken calculator'.  More able students use the decimal point in each calculation.  In the development phase students learn to brackets and powers to break down calculations.  The plenary allows students to explore the random, fraction and power buttons.
##### Differentiated Learning Objectives
• All students should be able to perform basic arithmetic and the order of operations using a calculator.
• Most students should be able use a calculator to evaluate problems involving powers and brackets.
• Some students should be able to use the ANS, square root, power and fraction button on a calculator efficiently.

#### Literacy in Mathematics – Creating Problem Solvers

Last year my school had a OFSTED trial inspection. Whilst the maths team recieved favourable feedback the inspectors noted a need for a focus on whole school literacy. Because of this I was asked to demonstrate how we develop student’s literacy in mathematics. Literacy in Mathematics By developing student’s literacy in mathematics we aim to […]

#### Angles in Polygons

There are two key learning points when solving problems with angles in polygons.  The first is to understand why all the exterior angles of a polygon have a sum of 360°.  The second is to understand the interior and exterior angles appear on the same straight line. Students can be told these two facts and […]
