LumoThe foundations of KS1 maths
Key Stage 1 covers Years 1 and 2. It's where children build a real feel for numbers: counting confidently, understanding tens and ones, and knowing number bonds well enough to add and subtract without counting on fingers. Lumo also has Reception topics for children who are just starting out.
Count, read and order
Counting objects, knowing number names, comparing which group has more or fewer, and reading and ordering numbers to 20 in Year 1.
Tens and ones
Seeing that 34 is 3 tens and 4 ones, working with numbers to 100 in Years 1 and 2.
Pairs that make a total
Ten-frames with counters help children see number bonds to 10. Missing-number bonds such as 7 + ? = 10 build towards adding and subtracting within 20.
Within 20, then 2-digit
Adding and taking away within 20 in Year 1, then with 2-digit numbers in Year 2.

- 2D and 3D shapes
- Number stories and brain teasers
Year 2
- The 2, 5 and 10 times tables
- Halves and quarters
- Coins and change
- Telling the time to quarter past
- Two-step number stories and brain teasers
Gentle, adaptive practice for young learners
- Finds the right level. A short, friendly check places your child, then every session adapts: easier after a wobble, a stretch after a good run.
- Read-aloud on every question. Children who are still learning to read can hear each question.
- Kind by design. A wrong answer never brings a red cross or a buzzer. The glow just dims and Lumo says "not quite, let's look again together".
- Short tests. A 10-minute maths test for each year, and a gentler 5-question "Little Test" for Reception.
- Speed rounds and times tables from Year 2. A 60-second round of typed mental arithmetic, and a drill for the 2, 5 and 10 times tables.
- A parent area. See each child's level, weak spots and what's due for review, add several children and set a daily goal.
