Base Ten Number Blocks
By Elementary Connection
Open iTunes to buy and download apps.
This simple app allows you to use base ten blocks in the form of ones, tens, and hundreds to aid in solving addition and/or subtraction problems.
This app works great for preschool students through elementary school.
Created by educators for education.
What's New in Version 1.2
-Added separate addition and subtraction modes.
I read the reviews and the app looked like it would work great for my classroom, but it didn't. It had some bugs and didn't always regroup correctly. My students had difficulty keeping the blocks on the correct box, the hundreds couldn't hold 9 hundreds very well and if you borrowed while subtracting the regrouped tens should kick out the ones that were already there, making it confusing. It was also very easy for them to accidentally regroup while subtracting-they would accidentally take the ten in the ones place while trying to trash it an ruin the whole problem because there is no fast way to get ride of them once that happens. I really wanted this app to work, but it didn't. I also do not like how it automatically regroups when it is set on addition my students would get confused and stop counting and then it was hard to help them and tool that was supposed to help because,e a hindrance. It is just awkward to use.
Great idea, but it is very cumbersome to use. You have to be VERY careful when tapping because you can't go back unless you clear the whole thing. Particularly frustrating is regrouping while subtracting. There is not enough room in the tens block to hold more than 10 ten bars, so they overflow into other blocks. Then if you try to grab a ten bar that overflowed into the ones block it frequently brakes apart into ones and you can not regroup it again to be a ten. It would also be helpful to be able to track how much you have put into the trash can. After using it for several minutes it got stuck with 9 units in the ones block and couldn't clear it. Please update soon. My son could really use this app!
Finally an app that is simple, useful, and effective! This does exactly what it needs to do to help my kids learn to "see" the process of addition and subtraction. I also love it as a teacher in my classroom to both teach the concept and also to have my students use the app as a visual when they are working on their independent work to solve their addition and subtraction problems. Thank you!! I love it!
