What is subtraction?
Subtraction takes one amount away from another, or finds the difference between them.
How to teach it
Model 'take away' and 'difference' (counting up) with objects and a number line. For larger numbers, partition or use column subtraction with regrouping.
Worked example
Common mistake
Subtracting the smaller digit from the larger in each column regardless of order, instead of regrouping.
