Adding and subtracting algebraic fractions

Download the PowerPoint here.

Two lessons (at least).

Includes quite simple ones…

Has a task that worked really well with my class. Write the missing step. Cognitive load and that.


Plus some questions.

Goes onto more complicated examples and exercises.

As an aside, I posted a picture from this resource on Twitter and it got (at the time of reading) close to 200 likes and I ended up picking up about 50 new followers.

Which I don’t quite get. Normally my stuff gets 0-20 likes despite being pretty similar. I don’t understand social media at all.
