Field test SkippyNums: An accessible skip counting app

'Skip' through this fun accessible math app! Practice skip counting by twos, fives, and tens!

Update September 2023: SkippyNums has been released in the App Store. It is FREE and fully accessible with VoiceOver. Check out the updates and details here!

“2, 4, 6, 8, who do we appreciate?” SkippyNums! SkippyNums is an accessible iPad app that helps young students learn to skip count. Skip counting is defined as a method of counting numbers by adding the same number every time to the previous number.

Why do we teach skip counting?

Learning to skip count helps students see patterns in numbers and is a foundation for number sense. It also helps students increase their fluency in regular counting and adding, boosts confidence when it comes to making money transactions, and is a precursor for multiplication and division.

SkippyNums app

While there is a plethora of educational apps that reinforce skip counting, these mainstreams apps are visual in nature and are not accessible with a screen reader. Created by a tech savvy recent high school grad who is visually impaired, SkippyNums has been designed specifically for students who use VoiceOver. This app works best with VoiceOver on!

Game Play

Customize your game play:

Note: SkippyNums can be played without VoiceOver. The announcements are VoiceOver announcements and are not given if VoiceOver is off. You can tap on each group of objects to hear and count the object sounds.


The game automatically keeps track of the player’s score and the number of tries; the score is available on the question screen. If playing the timed games, when the time is up, you have the option of Next Round (which accumulates the scores even when a new round begins or after choosing a different skip count number) or Reset Score. The Untimed games have unlimited rounds and the scores continue to accumulate. Select the New Game button to restart the scoring.

10-frame layout

The layout of the groups is intentionally designed to mimic a 10-frame. As students begin to build spatial concepts, this layout subtly helps students learn there can be up to five groups in a row. One student mentioned his personal shortcut – to start counting with the number six in the second row (instead of counting through 1-5 in the first row before moving to six in the second row).


Earcons are sounds that have meaning. Did you notice the subtle sounds used in this app? There is a subtle tone for each group of 2s, a two-note chord for each group of fives, and a three-note chord for a group of ten. Earcons are designed to provide more information quickly – without the use of longer descriptions/words. Once the student understands the concept (in this case skip counting) and what the earcon represents, the students can learn to listen for the earcon and move quickly to the next group without listening to the full VoiceOver announcement.

App Feedback

SkippyNums is still under construction but is ready for field testing and feedback. The app is designed to be used with VoiceOver and what has been built is fully functioning. The current next steps might be to develop a teaching level, where each step is broken down; the student is given one step, completes the step before being given the next step. What would like to see added to SkippyNums?
