Theory/practice connections

Knowledge of morphemes is an important part of learning to spell. Morphological knowledge involves understanding the relationship between base words, for example, lay, and related words, for example, plays, players, played.

It also includes such understandings as adding -s to form many plural nouns, or adding -ed to mark past tense in most verbs. Some research shows that it is more efficient for writers to store spelling of words in their long-term memory by their morphemes rather than their whole-word forms as it is easier to make generalisations around morphemic relationships within words.

As this is a more advanced type of spelling knowledge, explicit teaching is important (Westwood, 2008:31).

Learning intentions

We are learning that the base word can change when adding suffixes.

Success criteria

I can find patterns when adding a suffix to base words.

I can make a generalisation about how the base word changes when adding a suffix.

Role of the writer

Text encoder – knowing and using base words, suffixes and prefixes to spell words.

Group Size

Whole class, or small group (4-6 students).

Lesson Sequence

  1. Reread the picture book for pleasure.
  2. Draw students’ attention to verbs in the text that end with the suffix -ing and list these on a chart or whiteboard, for example, bothering, planning, having.
  3. Next to each word, write the ‘word sum’ made up of the base word and the suffix -ing, for example, bother + ing.
  4. Discuss the different changes to the base word when the suffix -ing is added, for example, no change or final letter doubled or final letter deleted.
  5. In pairs or small groups, play “What’s my rule?" Give students time to talk, formulate and test some generalisations for the changes to the base verb, for example, when the verb ends in -e the final -e is dropped before adding the suffix -ing.
  6. Share students’ rules with the whole group and record ideas on a chart. Encourage students to look for other examples in subsequent reading and writing sessions. Test these rules with other verbs and modify as new learnings are made.
  7. Encourage students to use these understandings when writing.

Differentiation

Students can be selected to work in mixed ability groups to provide support at different levels. The teacher might decide to introduce only one type of change to the base verb in a single lesson.
