If a learner struggles
- Find the misconception: Forgetting the capital or end mark. Check each one.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Use sentence frames.
- Guided practice: work through one example together and let the learner try the next one.
- Reassess: use the quiz again or the worksheet.
- Move on when the learner shows Silver-level evidence independently.
For parents and guardians
In this lesson your child writes complete sentences. You do not need to be an expert to help.
- Ask them to write about their day.
- Check for capital and end mark.
- Praise effort.
- Ask “how do you know?” after each answer, and listen.
- Praise effort, not only right answers. Mistakes are how we learn.
- Ten to fifteen minutes a day is better than one long session.
