Just right after the adding and simplifying, I learned how to subtract fraction it is the same at the start but there is a big surprise ahead of you. It is quite complicated at the start but you'll get the hang of it. I made a DLO that will show you to subtract fractions in just 3 minutes.
Next Step: Multiply fractions
Reflective comment: I think I did pretty well but I had a little few stops and next time I will surely remember to stop on pausing and the the DLO more clearer.
I hope you like it!
