Addition Algorithm vs FlashTables

No ads now or ever! Addition Algorithm – Rigby Maths is an interactive app that teaches and reinforces the standard written (column) addition algorithm. Learners build answers one column at a time—focusing on place value, accuracy, and the correct method—so they don’t just “get the answer”, they understand how the answer is made. Across five levels, the difficulty grows from first-time algorithm practice, to carrying (regrouping/renaming), to larger place values, adding three numbers, and finally working with decimals (tenths and hundredths). The app includes guided “Learn” tutorials and an on-demand help feature with clear voice prompts, plus optional visual supports like a carry helper overlay, tens frames, and visual dots to make the maths more concrete. Progress is tracked with a mastery percentage per level, and the question wording is customisable—choose whether the app says “add” or “plus”, and whether it uses “carrying”, “renaming”, or “regrouping” to match what learners hear in class. It’s useful for independent practice at home and structured practice in schools, giving students confidence with the algorithm while giving adults a simple way to see steady improvement over time.

Win 3 perfect races and the table is MASTERED: you earn a star that never disappears. WORK UP TO GRAND CHAMPION Master every table to unlock the Championship, then win it for both multiplication and division to become a Grand Champion. Mastery stars never go away - players only ever move forward. SEE EVERY TABLE A built-in learn mode lays out any times table as a full reference chart - every fact, any operation - so players can study before they race. BUILT ON HOW CHILDREN REALLY LEARN FlashTables is grounded in research on how children actually learn math facts. Real fluency comes from short bursts of fast recall, so that's exactly what the game trains - a friendly clock, instant feedback, and repetition until the answer is automatic, then locked in for good with mastery that never fades. Even the wrong answers on the tiles are deliberate: they're the specific mistakes kids really make, so every question teaches. THREE WAYS TO ANSWER Tap a multiple-choice tile, type on the number pad, or just SAY the answer out loud - on-device speech recognition, so audio never leaves the phone. CHOOSE THE TABLES YOU WANT Set the range that fits your child - practice the 1-10 tables, or go up to 1-12 for the 11s and 12s. Change it any time, and open Practice to every table whenever you like. BUILT FOR YOUR SCHOOL'S TABLES The 1-10 tables line up with what most US classrooms expect - Common Core fluency by 3rd grade. Switch to 1-12 for states that go further, like Florida and Virginia. The Championship draws from whatever range you pick. ALL YOUR CHILDREN CAN PLAY Up to 5 player profiles, each with its own progress, avatar, theme, and settings.
