Hundreds Chart Deluxe app for iPhone and iPad

A typical hundreds chart is a 10-by-10 grid with numbers from one to one hundred printed in the squares or cells of the chart. Usually the starting number on a hundreds chart is 1, but some teachers like to change the starting to a different positive or negative integer. Hundreds Chart Deluxe allows the user to select a starting number between -10 and +10.

The educational purpose for using a hundreds chart can include learning to skip count. Skip counting is a method of counting where a constant number is added to the previous number in the sequence. Skip counting can also be a process of counting down by a certain constant. Skip counting can use any number but typically 2, 5, 10 and 100 are used.

Hundreds Chart Deluxe provides 6 different markers. The markers can be any of nine colors. As students mark patterns on the hundreds chart they will observe that designs emerge. Counting be 3s ,for example, produces diagonal lines.

Using different markers and different colors to lay patterns over patterns reveals to students the concept of common multiples. The idea of least common multiple, LCM, is important for developing algebra skills.

Hundreds Chart Deluxe 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 Hundreds Chart Deluxe 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.
