Clever Goats is an iPad app development company that has produced a handful of nice iPad apps designed to help students learn to read and write. Phonics Fun: Long and Short Vowel Sounds is one of the Clever Goats apps that I recently tried.
Phonics Fun: Long and Short Vowel Sounds asks students to trace letters, identify vowels within words, and then identify objects whose names contain short and long vowel sounds. A half-dozen activities is available for each vowel. Clear, narrated directions are provided to students as they work through the app. Feedback is provided to students at the completion of each activity screen.
Phonics Fun: Long and Short Vowel Sounds is currently (April 28, 2014) available for free. The app usually costs $1.99.
