WOW, Another alternative method to column subtraction made EASY!
Although this method is not as easy as it sounds it makes a great starter discussion and debate with your maths classes. Demonstrate with an example and give your pupils a few questions to practice this method and start a discussion.
Please leave a comment and let us know the feedback from your pupils.
Borrowing is definitely the hardest step to understand when performing column subtraction, I will try this the next time I am teachign this topic!
