One app, five ways to practise

SpeedSum aligns with the UK National Curriculum for mathematics at Key Stage 1 and Key Stage 2. Each game mode targets a specific aspect of arithmetic fluency — from raw speed and recall through to algebraic reasoning and times table mastery. Children can switch between modes to keep practice fresh and parents can direct specific modes via Coach Mode.

90 Second Challenge

The classic speed round

BeginnerIntermediateExpert

Answer as many arithmetic questions as you can in 90 seconds. Questions are drawn randomly across the selected operation and difficulty. The clock is always visible — teaching children to manage time pressure while maintaining accuracy.

Age / Stage

All ages · KS1 and KS2 (Years 1–6)

Operation Focus

Addition, subtraction, multiplication, or division — child selects at the start

Learning Benefit

Builds rapid recall of number facts. The time pressure trains children to retrieve answers from memory rather than computing them each time, which is the key mechanism behind arithmetic fluency.

Get to 100 Challenge

Progress as you grow

BeginnerIntermediateExpert

Earn points with every correct answer and work your way up to a score of 100. Questions become progressively harder as your score increases — starting simple and ramping up to keep the child working at the edge of their ability throughout the session.

Age / Stage

Ages 6–11 · Lower and Upper KS2 (Years 2–6)

Operation Focus

Mixed operations, scaling in difficulty as the score rises

Learning Benefit

Introduces adaptive challenge within a single session. Children experience a 'flow state' — neither bored nor overwhelmed — because the difficulty scales with their performance in real time.

Missing Piece Challenge

Find the missing number

BeginnerIntermediateExpert

Each question has a gap: a missing number or a missing operator. For example: 6 × ? = 42, or 15 ? 8 = 7. Children must reason about the relationship between numbers rather than just apply a known fact — developing deeper mathematical understanding.

Age / Stage

Ages 7–11 · KS2 (Years 3–6)

Operation Focus

Inverse operations: multiplication/division relationships, addition/subtraction pairs

Learning Benefit

Develops algebraic thinking and understanding of inverse operations. Children learn that maths is about relationships between numbers, not just memorised outputs — a key foundation for secondary school mathematics.

Traffic Light Challenge

Speed and accuracy, colour-coded

BeginnerIntermediateExpert

Answer each question and receive instant colour-coded feedback: green for fast and correct, amber for correct but slow, red for incorrect. The goal is to turn every answer green. Children can see at a glance which facts they have mastered and which still need work.

Age / Stage

Ages 6–11 · KS1 and KS2 (Years 2–6)

Operation Focus

Any single operation — ideal for targeting a specific times table or arithmetic fact set

Learning Benefit

Separates speed from accuracy in a visible, non-threatening way. Amber answers signal 'correct but not yet automatic' — giving children a precise target for improvement without feeling like failure.

Times Table Tower

Build the tower — unlock with a streak

BeginnerIntermediateExpert

Answer multiplication questions correctly to stack blocks and build a tower. Each correct answer adds a block; each wrong answer removes one. The goal is to reach the top. This mode is exclusively focused on times tables from 2× to 12× and uses a visual reward that makes progress tangible.

Age / Stage

Ages 7–11 · KS2 (Years 3–6)

Operation Focus

Multiplication only — times tables 2× to 12×, targeting the UK National Curriculum requirement

Learning Benefit

Provides concentrated, game-like times table practice with immediate visual feedback. The building mechanic creates a strong emotional response to both correct and incorrect answers, reinforcing memory consolidation.

🔒Unlocks after a 3-day consecutive practice streak — rewarding regular learners with a bonus game.

Premium: know exactly what to practise next

Every free account gets all five core practice modes. Premium turns each session into clear, fact-by-fact insight for you, and adds family Challenge Mode:

  • Times Table Mastery Heatmap — All 144 multiplication facts on one 12×12 grid, coloured green, amber or red from your child’s real answers. Tap any fact for the detail, or download a PDF to share with their teacher.
  • AI Tutor Feedback — A personalised, plain-English read of any session: what went well, which facts slowed them down, and exactly what to practise next.
  • AI mission suggestions — Coach Mode reads your child’s recent sessions and suggests a mission aimed at the area they find hardest, ready to tweak and send.
  • Progress analytics — Score trends, an activity calendar and per-game stats show how your child is improving week on week, not just how today went.
  • Challenge Mode — Siblings challenge each other, or you, to friendly maths duels. Nothing gets children practising quite like a rematch.
  • Premium sticker rewards — A bigger collection of digital stickers to award when your child completes a Parent Coach mission.

Introductory offer: £9.99 for your first year, then £19.99 a year · or £4.99 a month · whole family, cancel anytime. New families can try it free for 7 days.
