Best match
- Add AttackGrades 1–3Enemy drones drop in carrying numbers — solve the addition fact and tap the drone whose number is the sum to blast it.Play
- Snack Bar TapperGrades 1–3Customers walk down the counters with orders like 8 + 5 — build their cookie tray out of tens and ones and slide it to them before they reach the bar.Play
- Mental Math MesaGrades 2–3Fill a ten or split a near-double to add in your head — the counters show why the shortcut works.Play
Also practises it
- Column CrunchGrades 2–4Stack the numbers and crunch them one column at a time — ones, tens, hundreds — carrying and borrowing across the line to build each answer digit.Play
- Number Line JumpsGrades 1–2Hop a frog along the number line to add and subtract — each jump draws an arc, so you can see the math!Play
- Ten FrogGrades 1–2Hop the frog across the river one numbered turtle per lane — each +2 or −1 moves it along the number line, and it gets home only if the hops land exactly on 10.Play
- Subtract SquadGrades 1–3A squad lands, the chopper airlifts some away — count who's left and dial the radio to match.Play
- Regroup RallyGrades 2–4Subtract big numbers column by column — borrow a ten when the top digit is too small.Play
- Bond BreakerGrades 1–2Slide the paddle under a numbered brick, give the ball its partner number and launch — the brick only breaks when ball + brick makes 10 (later 20).Play
- Doubles DashGrades 1–2Two dot-groups flash up — read the double or near-double fast and tap the matching sum.Play
- Number Bonds BridgeGrades 1–2Tap stones onto the bridge piers to build the number bond — the raccoon crosses when the parts match the whole!Play

- Fact Family ForgeGrades 1–3Dial the hidden number of a bond triangle and watch it forge all four related facts at once.Play
- Sequence SprintGrades 2–4A robot conveyor belt rolls numbers past — spot the pattern and stamp the missing crate before it rolls off.Play
- Ten-Frame ForgeGrades 1–2Forge numbers with counters on ten-frames: build a number, complete a bond to ten, and add up to twenty — seeing the numbers, not just hearing them.Play
- True-False CircuitGrades 2–4Equations stream toward the OUT gate — judge each TRUE or FALSE before it slips through. Fast streaks surge the circuit faster!Play
- Ten Frame FlashGrades 1–2A ten-frame flashes up — read it in a blink and tap the number.Play
- Tally TowerGrades 1–3Count tally marks — gates of five plus the leftovers — and find the biggest count.Play
