/s/ blends Artic-U-Checks data forms for baseline and progress monitoring. 19 pages, including instructions. Each page contains data grids for 10 words and 10 sentences containing the target sound in the target position. When a student makes errors on /s/ blends during the initial evaluation, use these Artic-U-Checks to determine the position and severity of the errors, providing a baseline percentage for your IEP goal. Then use these same forms at the end of each marking period to measure and report progress. Tip: Make multiple copies of the blank forms and keep in a binder so you always have them handy during artic evaluations. (Note: If you purchased the full Artic-U-Checks CD from Speaking of Speech.com, you already have this).
