MathGuru Lessons

Lessons

Guided lessons that teach maths by doing. Your child works through a real activity, the help fades step by step, and the understanding sticks. No sign-up, no ads.

How lessons are different from games: a game lets your child practise a skill they already have. A lesson teaches a new idea — it shows it once, lets your child do it with help, then slowly takes the help away until they can do it on their own. Each lesson below is free and works on any phone, tablet, or laptop.

The full path from counting to carrying. Start at the top — each lesson gets your child ready for the next.

Count to Add

What adding means: join two groups and count them all. The very first idea, built from real objects.

Counting On

The first real shortcut: start at the bigger number and count up — instead of counting everything from one.

Friends of Ten

The pairs that make ten — 6+4, 7+3, 8+2 — known by heart, not counted.

Doubles

6+6, 7+7, 8+8 — and the near-doubles that follow once doubles are quick.

Make Ten

7+8? Make a ten first (7+3), then add what's left. The keystone strategy.

Tens & Ones

Too many to count? Bundle them into tens, and write the number as tens and ones.

Add by Place

47 + 21 — add the tens, add the ones. Two small sums instead of one big count.

Carry

When the ones overflow past ten, bundle a new ten and carry it over. The summit.

What are MathGuru lessons?

Most maths apps for young children are drills: answer a question, get a tick, repeat. MathGuru lessons are different — they are built like a patient teacher sitting beside your child. Each lesson takes one idea, shows it with objects your child can tap and count, lets them try it with guidance, and then quietly removes the scaffolding until they can do it in their head.

The addition lessons form a staircase from the very first idea of adding right up to two-digit carrying. When your child is ready to simply practise, the number games and the addition practice ladder are there too.
