Attached is a chart with visuals and words in their written form to target [r] vowels "air", "ear", "or", "ire", "ar", and "er" in the initial, medial and final word positions. Use as an informal evaluation tool to assess a student's productions of [r] vowels at the word level. A separate chart with visual cues is also attached that can be used by the evaluator to identify which [r] vowel is targeted in which words. I would suggest laminating and hole punching the chart and placing in a binder for easy flipping.
Use the given words for extension testing at the phrase or sentence level.
Also attached is a tool to easily record student responses. I would suggest making multiple copies of these and placing in the binder so that they are ready to go when you need them.
