Tacticality Software has built three great programs for the iPhone and iPod Touch. The first is called Countby and helps Pre-K and Kindergarten students count to 100. The next app is called Timesby and it helps students practice multiplication on all numbers up through the number 9. The final app is called Sentence Spin.
