Ten minutes a day this week
Short and daily beats long and once. A word met on five separate days is remembered; a word met five times on Thursday night mostly is not.
Monday
Read the list together. Say each word, clap its syllables and find the pattern in it.
Tuesday
Look, say, cover, write, check — each word once from memory, then check the letters.
Wednesday
Use every word in a sentence, out loud or on paper, so each one means something.
Thursday
Practice test: a grown-up reads each word aloud. Circle the misses for tomorrow.
Friday
The test. One try per word, no letters given. The circled words go first.
