**Move beyond counting by 1's to more efficient strategies with number!**
Your child can now count objects up to a high number, perhaps 50 or even higher. Now what? The mathematical skill of subitizing is "instantly seeing how many." The tasks in this app are designed to develop this skill by flashing a graphic of objects on screen for a limited amount of time before vanishing. This constraint makes counting all objects a much less efficient strategy for the child. The learner must invent strategies that help him/her to see quantity in more flexible ways. This activity fosters development of number sense by facilitating progression towards this flexibility with number. In particular, children decompose and compose numbers in various ways. For example, seeing 13 as 6 + 6 + 1 or 5 + 5 + 3. Subitizing also helps develop the ideas of addition and subtraction.
*six different game modes
*recommended for children in grades K-2
*meets a variety of Common Core State Standards for Mathematics
What's New in Version 1.1
-visual indication that the next image will appear in a few moments
-dot cards module now includes dots of two colors to suggest particular ways to subitize (iPad)
Concept for the app is good and it ties well with how most school systems are wanting math concepts presented. A better description of what each section entails would have been helpful. I had to purchase it to really find out what it contained. Biggest drawback as an actual teaching tool is the limited timer. I work in K and a maximum of 4 seconds is not nearly enough even with the subitizing aspect of it. It would also spool longer than I would like in an app and would not present the visual but the timer would tick and you would just have to push any number to get it to forward. Based on these issues I would most likely NOT recommend it to others.
Just what I've been looking for!
I'm a first grade teacher. I've been needing a good app for helping students learn to subitize with these tools. We use Dreambox at our school, and it's wonderful, but I've needed a good tool to teach subitizing for those kids that don't naturally subitize and need the scaffolding of the 1-4 second view. Great app.
