Zero Our Hero vs Addition Algorithm

Who is this app appropriate for? Zero Our Hero is a teacher-designed, research-based Mathematics app for students aged 7-12. What content is covered? The app focuses asks students quality questions related to the six aspects of whole number place value (Rogers, 2014). The aspects are: Calculate, Compare/Order, Count, Make/Represent, Name/Record and Rename. Who designed the app? The app is designed by experienced primary school teacher Dr Angela Rogers and is based on her PhD research into the teaching and learning of place value. What are the features? -Includes over 450 different questions specifically designed to address common student misconceptions in whole number place value. -Questions are sequentially presented so students work at their own pace through four stages of difficulty. -Students are continually encouraged to see mistakes as learning opportunities and are provided with three opportunities to try each question. -Students are able to work independently on the app. -No distracting music or annoying sounds included. Why should you purchase this app? Zero Our Hero is designed to be the most comprehensive place value app currently available. It is a wonderful resource for both teachers and parents to support their children in this critical area of the Mathematics curriculum.

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.
