Fantastic Online Manipulatives

How I Use It

I use it for those students who need to see in a visual way without the distraction of the blocks in front of them (falling off the table, etc.) students can see how the ones become tens and tens become hundreds. They can also see how the tens get 'broken' up as they go into the ones for subtraction. A really great way to show the "borrowing" and "carrying" of the traditional algorithum. The only drawback is that at times it can be difficult to get into the section you want to be in, you have to give very specific directions for students. I have used this site successfully with children in grades 1-6.
