This resource includes 4 centers for studying SHORT A. Each center includes printable manipulatives, directions a book recommendation, color and b/w printing options, sample photograph, and an extension activity/recording sheet that involves writing short a words.
Trash or Stash: distinguishing short a among other short vowel sounds
Alligator Snap: sorting short a words by family
Bag that Cat: distinguishing short a from long a
Splat Mats: distinguishing short a among other short vowel sounds
I would recommend this resource for kindergarten and first grade using teacher discretion for the appropriate time of the year to implement it. It could also be used for ESL students or for those students needing remediation in upper elementary grades.
