Codes: AC9E3LY10, AC9E3LA10, AC9E3LY09. Aim: read meaningful base + prefix/suffix combinations and explain the change. Bring: check/recheck, fair/unfair, care/careful, help/helpful cards.
- Invite · 2 min. Say: “If I check a record and then recheck it, what do I do?” Accept “check again” with an example.
- Model · 5 min. Build
re + check → recheck. Point to the base and prefix. Read the whole word through, then use it in “We recheck our count.” State that not every word startingrehas this prefix. - Guided pairs · 6 min. Build
un + fair → unfairandcare + ful → careful. Ask how the meaning changes. Blend/say the whole words at a natural pace; use letter patterns taught locally. - Choice task · 7 min. Pairs choose two base/change pairs and make a sentence for a real classroom purpose:
It is helpful to label a sample;It is unfair to change only one person's rule. Teacher checks that a learner understands meaning, not just cuts a word visually. - Counterexample · 3 min. Show red. Its first two letters are
re, but they are not a prefix meaning “again” here. Say: “We check the whole word and its meaning; a matching start is not enough.” - Check · 2 min. Everyone reads recheck and careful, marks base and addition, and says the meaning. Focus learners receive a new card unhelpful to test transfer. Record untaught grapheme support separately.
