This abacus will teach, not calculate like the Japanese and Chinese abacus, while using subitizing (quantity recognition) and visual strategies to support learning and understanding. Perfect for visual learners! This unique double-sided abacus is grouped in fives and tens for quick recognition of quantities. The second side of the abacus focuses on trading to the thousands. Learn the facts easily by: * visualizing quantities, * minimizing counting, and * developing mental strategies. Those learning arithmetic with the Cotter AL Abacus have a better understanding of basic concepts and need less time to master arithmetic. Although children do enjoy using the abacus, it does not become a crutch. Stan, age 5, was asked how much is 11 plus 6. He replied, “17!” When he was asked how he knew, he replied with a grin, “I’ve got the abacus in my mind.” App has links to sample addition, subtraction, multiplication, and division lessons as well as detailed use information. ## Cotter AL Abacus Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/Purple211/v4/14/78/c7/1478c7a2-a71e-860a-92ba-255b55002099/mzl.qrxvjcmr.png/640x960.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/Purple221/v4/7f/56/0f/7f560f83-8877-7ca1-664a-ee080a47ce3c/mzl.lmeujxty.png/960x640.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/Purple221/v4/6e/2d/3c/6e2d3c25-036d-2f05-0db5-6163752df502/mzl.esaxbcfk.png/640x960.png) ## Cotter AL Abacus Rating Breakdown in United States - 5 stars: 3 (50%) - 4 stars: 0 (0%) - 3 stars: 1 (17%) - 2 stars: 1 (17%) - 1 stars: 1 (17%) ## Cotter AL Abacus Reviews in United States ### **--- "Just ok" You can’t move the beads to alternate spacing to show adding as demonstrated in the right start math book. The beads only go to the far left and far right. We were trying to use the app to get us through lessons while we search for our missing abacus, but this is not a great substitute. -- Mama Marianne, 2024-11-14 ### ***** "So far, so good!" I downloaded this app so that two of my children could do their Right Start math lessons at the same time and so far it has worked perfectly. I have a new iPad and the app works beautifully with no delays or issues. -- Cjbt42906, 2021-08-13 ### *---- "Horrible app" I wouldn't complain if it was free. But I spent $2 on it and I'm going to have to just buy a physical abacus. I thought the app would get us through the rest of the week until I could search for the lost abacus this weekend. This is terrible, it takes for! Ever! For it to recognize your finger, so doing a whole math lesson takes impossibly long. We spent two days doing a lesson that should have taken half a lesson time. So much wasted time. I should have just pulled out some counting beans or Legos or something instead. -- thelovelyamber, 2017-09-22 ### ***** "Great extra abacus for Rightstart Math!" I love that we have the convenience of an extra abacus on our iPad for home and on the go! Thanks! -- MsMama2, 2014-09-07 ### **--- "Could be great, but..." It won't respond to inputting data. When we try to enter anything, it freezes, then it may or may not move the beads 2-3 minutes later. I can't teach the program like this. -- MomWonder, 2014-04-28 ### ***-- "Great App But Needs An Update" This app is great; however, with the release of io7, one side of the abacus doesn't work correctly. This is understandable, but enough time has passed for them to fix problems. The owners probably didn't create the app, but this should have been resolved already. Otherwise the curriculum is perfect. While we're waiting on the fix, I use the Number Rack app. It would be nice to go back to using one app instead of two, though. -- fay_jay, 2013-11-01 ### *---- "Worked great before but now it's not" We have the Righstart Mathematics curriculum and have used this app in the past on iPhones and iPod touches with no problems. I recently bought a new iPad and tried using it but half the abacus is not visible in landscape mode. I then tried on my iPhone and it has the same problem on there. Please fix this as it was working perfectly before. -- gustafsonfamily, 2013-10-16 ### *---- "Bug..." Great idea to travel with our curriculum, however a bug makes only half the abacus viewable in landscape mode. Please fix and update!! -- Elly5280, 2013-09-26 ### ****- "RightStart" Love having the AL abacus as an app to use with my Kindergartener. For $2 though I wish it had audible clicks when moving and clearing the beads. I'll update to 5 stars when/if that update is made. -- Neighmoo, 2012-10-15 ### ****- "Just what I needed!" This app is wonderful. I use the Slavonic abacus extensively in my teaching and tutoring, so this is so great to demo what I am doing to show the students. My only wish is that there would be sound effects that would be similar to using a real abacus. This would help give sensory feedback, making the learning experience closer to the real thing. I have been recommending it widely. -- susanrm, 2012-10-04 [View all Cotter AL Abacus reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Cotter AL Abacus Discovered Keywords -
