Are there specific apps that you have found to be more successful than others in teaching your developmentally delayed kinder and first graders basic academic skills?
We just published our study about the use of apps in primary school: https://www.researchgate.net/publication/270280736_EXPERIENCES_WITH_IPADS_IN_PRIMARY_SCHOOL
see Pixiedust Lite. it's really engaging. Kids can start creating their own pics through images, drawings and they may write and read as well. Easy to use. All creations are later shared in an cloud.
As a fellow human being, I empathise with those with "developmental delays". However, in response to your question -- as a cognitive scientist, educational psychologist, and practicing psychologist (for over 40 years) -- I must note that the application and/or utilization of ipads and similar computer devices will NOT increase their IQ a single point! That said, it may be wiser to spend the considerable amount of funds that would have been used to purchase ipads and similar computer devices on the application of basic PROVEN cognitive-behavioral techniques in the classroom that can improve the learning and life-skills of this particular group of students (and fellow human beings) -- with the goal of helping to make their lives more independent, more satisfying, and happier!
I hope that this answer helps or that it may, at least, stimulate others to provide you with the answers you seek.
Thank you for your opinion. I use the Unique Learning system level a and level aa books to teach reading. New Mexico is a state which has adopted the Common Core which raises the bar for all students to be taught more informational text. News 2You, a part of the Unique Learning system, provides up-to-date articles which I present and practice reading with my kinder and first grade students. The IEP goals which came with the children from developmental pre-school or other teachers present the need to use iPad apps which teach numbers, letters/sounds and words. I am searching for someone who uses iPad apps listed by Cherokee County School District Office of Special Education to discuss how the student use of the iPad apps to learn more about how to use them.
I have completed a number of reviews of apps - some of which may be appropriate. Overall though most of the apps are not supportive of any type of learning. The url of the reviews is http://tinyurl.com/ACARA-Apps
I have also published in this area - see references below.

I am currently reviewing Geometry apps and will hopefully have a conference paper out soon.
