What students are learning
R-controlled patterns are sometimes called bossy-r patterns. The nickname can be memorable, but instruction should still focus on the letters, sound, position, and word meaning.
The spellings er, ir, and ur often represent similar sounds in many dialects, which makes spelling more difficult than reading. Students benefit from word families, morphology, and repeated exposure.
