Have you heard or seen the Grasshopperapps ? I tell everyone who works with emergent readers, writers or learners about Grasshopperapps.com. They produce many wonderful free apps as well as for pay apps (typically .99) for emergent reading, writing, spelling, numeracy, sorting, patterning, categorizing as well as perceptual skills (matching, puzzles).
Visiting their website or searching in iTunes for Grasshopperapps will provide you with over 80 different apps to meet the needs of your emergent learners.
Some of their wonderful qualities of their apps are their clean presentation, wonderful, real images, ease and consistency of navigation and interaction in all of their apps. A huge bonus is the ability to customize within the app (yes, really – you can customize levels of skills of the app!! – I tell everyone because most people are not used to having the option available to them in apps!). Here is a typical example of the settings page where you can customize the the sound, word highlighting, story highlighting.
In the number, sorting, puzzles, letters or spelling apps you have a choice of the number of items, range of numbers, letters or lower/upper case letters presented. Customizing the activity by import your own pictures and recording your own sound is always an option in the settings.
Grasshopperapps also has story book apps that have wonderful kid centered real pictures and stories that will read aloud. I really love the grasshopper apps to work on specific skill development. Visit their website often, they are developing new apps on a regular basis and often offer them for free when they first come out!
Check them out . It will be well worth your time!
