1

Place Value Power

Before a single sum is attempted, children build rock-solid understanding of hundreds, tens, and ones — the conceptual engine behind all 3-digit addition. Every lesson uses physical and visual tools so the abstract becomes concrete.

  • 1.1Hundreds, Tens, and Ones — What They Really MeanIncluded
  • 1.2Reading and Writing 3-Digit Numbers with ConfidenceIncluded
  • 1.3Comparing and Ordering — Which is Bigger and Why?Included
2

Addition Without Regrouping — Building the Column Method

With place value secured, children are introduced to the column addition layout using examples that don't require carrying. They learn the correct procedure, layout habits, and vocabulary before any complexity is added.

  • 2.1Setting Up Columns the Right WayIncluded
  • 2.2Adding Ones, Tens, and Hundreds — Column by ColumnIncluded
  • 2.3Adding Three Numbers in a ColumnIncluded
3

Regrouping (Carrying) — Cracking the Trickiest Part

This is the heart of the course. Children are guided carefully through what regrouping actually means — not a trick, but a natural consequence of place value — and practise it one column at a time before combining steps.

  • 3.1What is Regrouping? Understanding the WhyIncluded
  • 3.2Regrouping from the Ones ColumnIncluded
  • 3.3Regrouping from the Tens ColumnIncluded
  • 3.4Double Regrouping — Carrying Twice in One SumIncluded
4

Estimation and Answer-Checking Strategies

Accurate calculation is only half the skill — children who can check their own work are genuinely independent. This module builds estimation fluency and introduces practical checking methods that children can use for life.

  • 4.1Rounding to the Nearest 10 and 100Included
  • 4.2Using Estimates to Check Column Addition AnswersIncluded
  • 4.3Mental Check Strategies — Adding On and Near-DoublesIncluded
5

Real-World Word Problems

Mathematical procedures only truly stick when children can deploy them to solve real problems. This module builds a reliable word-problem method, reduces anxiety through familiar contexts, and ensures children can show organised thinking.

  • 5.1Reading Word Problems Without Panic — A Decoding MethodIncluded
  • 5.2Solving One-Step 3-Digit Word ProblemsIncluded
  • 5.3Two-Step Word Problems and Showing Clear WorkingIncluded
6

Building a 'I Can Do Maths' Mindset

Skills without confidence don't transfer. This final module consolidates everything learned, explicitly celebrates progress, and equips children with the self-belief and independent strategies to tackle harder maths ahead — for good.

  • 6.1Mistakes Are How Maths Brains GrowIncluded
  • 6.2My 3-Digit Addition Toolkit — Putting It All TogetherIncluded
  • 6.3What Comes Next — Bridges to 4-Digit Addition and BeyondIncluded

I know exactly what it feels like to sit beside a child who's crying over a maths worksheet — and feel completely helpless about how to explain it differently.

Whether you're a parent at the kitchen table, a homeschooling mum or dad trying to cover everything, or a classroom teacher with 30 different ability levels in front of you — the moment a child decides "I'm just not a maths person" is genuinely heartbreaking. And it happens far too early, far too often.

Here's what I've learned from years of teaching primary maths: 3-digit addition is one of the biggest confidence turning points in a child's early maths journey. Get it right, and everything from multiplication to long division feels more accessible. Get it wrong — rush it, skip the foundations, or just drill procedures without understanding — and you plant a seed of doubt that grows for years.

That's exactly why I built Little Number Ninjas. Not another worksheet pack. Not a passive video to babysit your child. A real, structured learning journey that explains the why behind every step, uses visuals and games that actually engage young brains, and gives you — the adult in the room — the language and tools to be your child's champion, not just their homework supervisor.

The lessons are short, the language is simple, and the results speak for themselves: kids who finish this programme don't just get the right answers — they want to show you their working. That pride is everything.

If your child is ready to go from confused to confident, I'd love to be part of that journey. Jump in — the first lesson is waiting for you right now.
