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.

  1. Monday

    Read the list together. Say each word, clap its syllables and find the pattern in it.

  2. Tuesday

    Look, say, cover, write, check — each word once from memory, then check the letters.

  3. Wednesday

    Use every word in a sentence, out loud or on paper, so each one means something.

  4. Thursday

    Practice test: a grown-up reads each word aloud. Circle the misses for tomorrow.

  5. Friday

    The test. One try per word, no letters given. The circled words go first.
