Calculations using BIDMAS +/- numbers - Edexcel KS3/KS4 (Middle/High ability)

Hi,

This lesson is based around the basic understanding of BIDMAS. I have broken this lesson down into 3 stages; using BIDMAS with positive and negative numbers, cancelling numbers as a fraction and using the inverse function of an equation. There is a good range of differentiation and scaffolding which will cater towards middle to high ability students. I have used a range of AfL to check understanding and cover misconceptions. The last learning objective gives students the chance to work independently and use their prior or current knowledge to work out the questions stated. (The last task can be given to higher ability students.)

The main activities can be displayed on the board for the students to copy into their books as they show their working out. In addition to this, most slides have answers and worked solutions.

I have attached two starters to this lesson so that basic skills can be addressed before the lesson starts. This lesson will take 2/3 lessons for a middle/top ability group. Please read the above before purchasing.

The learning objectives covered are:
- Use priority of operations with positive and negative numbers
- Simplify calculations by cancelling
- Use inverse operations to solve questions involving positive and negative values
