## Most critical reviews (6 lowest-rated)

### 3/5 — Needs an undo feature

*2013-08-24*

I wish there was a way to uncover a number without clearing the entire board.  If you make a mistake you need to start over.

**Developer response:** To uncover a number simply drag the marker off the chart.

### 4/5 — Hands On Hundred Chart

*2012-03-19*

Works well, however there should be a way to erase just one number without erasing all the numbers on the chart.  Sometimes you just touch a number by mistake but with this current program set up you have to erase all the numbers you have been working with in ordered to get that "one" erased.

**Developer response:** To erase one number simply drag the marker of the chart.

### 4/5 — Lovely, very useful

*2011-12-17*

Seems to have an arbitrary limit on the number of markers that can be placed -- so it's difficult to demonstrate the Sieve of Eratosthenes using a different color for each multiple of the first few primes. Also, removing a marker is difficult and haphazard. An undo button would be useful in addition to the eraser button which clears ALL of your work.  Overall, a very handy app for teachers. I'm grateful.

### 5/5 — Great for special Ed.

*2012-09-13*

Great for students who struggle with tracking on paper hundreds charts.

### 5/5 — teacher

*2012-06-02*

This is a great app with many features.  It's nice to be able to remove any marks from the number line.  With numerous ways to mark numbers kids can get a better sense of the numbers and their many multiples.  The speech setting is great.  The voice clearly pronounces the numbers.

### 5/5 — Best 100's board!

*2011-10-19*

This is a well designed math app! Artsy and fun to interact with. From basic to more advanced, the PDF lessons & instructions are very helpful. This app didn't look as cute as some other children's math apps so I almost skipped by it. Very glad I purchased it!
