I'll be able to use is with larger groups as well as introduce it to teachers throughout the school. I'd like to see an option to step back through calculations and the ability to always hide answers before you work through the question. ### 5/5 — What a fantastic teaching and learning tool!!!!!!!! *2016-05-04, version 1.0* A maths app that pictorially shows in real time how numbers add on or subtract. Subitising to improve manipulation and number bond knowledge. Singapore bar to look at visual values, base 10 to show those 5 and 10s clearly, htu to show carrying across visually... It's a superb teaching and learning tool. The children who get to use and see this app are privileged. ## Frequently asked questions about I See Addition and Subtraction ### What is the primary purpose of I See Addition and Subtraction?

We've changed the term 'Units' to 'Ones' to marry up with the new curriculum requirements; 2. On the Singapore Bar, if the numbers had too large a difference, it could result in one of the numbers being unreadable. We've sorted that... Well actually, Doug, our amazing developer sorted it! But he is good like that!! ### 1.0 — 2016-05-03 No release notes. ## Apps similar to I See Addition and Subtraction | App | Rating | Price | Category | | --- | --- | --- | --- | | [Blending Board](https://appshunter.io/ios/app/blending-board/id1521114657) | 4.3 (82) | Free | Education | | [Curiscope Virtuali-Tee](https://appshunter.io/ios/app/curiscope-virtuali-tee/id1135840956) | 4.0 (73) | Free | Education | | [WhiteBoard by LiveBoard](https://appshunter.io/ios/app/whiteboard-by-liveboard/id1132607923) | 4.2 (332) | Free | Education | | [Limna: Art Gallery Prices](https://appshunter.io/ios/app/limna-art-gallery-prices/id1559202866) | 4.6 (336) | Free | Education | | [Dr. Berg](https://appshunter.io/ios/app/dr-berg/id1023723480) | 4.9 (2,936) | Free | Education | | [Monster Math : Kids Fun Games](https://appshunter.io/ios/app/monster-math-kids-fun-games/id931943412) | 4.5 (32,070) | Free | Education | ## More apps by Alan Peat Ltd - [The Pocket Curriculum](https://appshunter.io/ios/app/the-pocket-curriculum/id800369940) - [The Alan Peat Pocket App of Exciting Sentences](https://appshunter.io/ios/app/the-alan-peat-pocket-app-of-exciting-sentences/id868248287) - [Exciting Sentences: Pupil Edition](https://appshunter.io/ios/app/exciting-sentences-pupil-edition/id896468597) - [Science Fiction Story Machine](https://appshunter.io/ios/app/science-fiction-story-machine/id921657105) - [The Fairytales Story Machine](https://appshunter.io/ios/app/the-fairytales-story-machine/id935608063) - [AnyWord Xword](https://appshunter.io/ios/app/anyword-xword/id957111997) All apps by Alan Peat Ltd: https://appshunter.io/developer/868248290 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
