Subtraction in 30 Days

Subtraction is where many children first decide they're "bad at math." This course is the confidence rebuild.

Subtraction struggles almost never start with subtraction. They start with borrowing being taught as steps to memorise rather than a concept to understand. A child who doesn't know WHY they borrow will make consistent errors they cannot fix themselves — and that helplessness compounds into math anxiety. This course fixes the root, not the symptom.

Has your child started avoiding subtraction? Making the same borrowing errors over and over?

Drilling more facts will not fix a conceptual misunderstanding. If a child doesn't know what borrowing actually does to a number — that it moves one ten across to the ones column without changing the total value — they will keep making the same errors regardless of how much practice they do. The fix is understanding first, procedure second.

The three most common subtraction errors — and why this course prevents them

Each error has a specific structural cause. This course addresses each one directly.

1
Backwards subtraction (54 − 28 = 34)
Subtracting the smaller digit from the larger regardless of position. This is a conceptual error, not carelessness. Week 2's trade concept approach prevents it.
2
Forgetting to reduce after borrowing
The expanded method makes this impossible to forget because the reduced digit is written explicitly.
3
Zero confusion
Borrowing past a zero without going further up first. Week 3 addresses this with step-by-step worked examples and dedicated worksheets.
