Hands-On Math: Interactive Hundreds Chart creates a virtual math playground where students explore, investigate and discover mathematical concepts. Students use colored markers on the Interactive Hundreds Chart to represent patterns and number sequences.

Using Hands-On Math: Interactive Hundreds Chart students can develop the following important mathematical concepts:

Skip-Counting

Number Patterns

Multiplication and Division Facts

Prime and Composite Numbers

Least Common Multiple

Divisibility of Numbers and more...

An extensive Instructor's Guide for this app is available at the support website. Download the document and install it in iBooks to access ideas about how to use the Interactive Hundreds Chart for teaching elementary mathematics.

Extremely easy for students and teachers to use. Tap a color and a marker, then tap numbers on the chart. To remove a marker simply slide it off the chart. Erase all markers by tapping the eraser.

Note to reviewer: Simply slide a marker off the board to remove it. There is no need to erase entire board if you make a mistake.

### Needs an undo feature

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.

### Lovely, very useful

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.

### Hands On Hundred Chart

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.
