Choose words with a reason
A list works better when its pattern is visible.
Group words that share a spelling feature—such as a vowel team, suffix or consonant pattern—rather than combining unrelated words solely because they appear in the same textbook week. Add one or two known words so the learner can compare the new pattern with secure knowledge.
For irregular high-frequency words, identify the regular part and the unexpected part. Asking a learner to memorize the whole visual shape gives less reusable information than discussing which sounds match the usual spelling and which letters must be remembered.
