Words to know
a fact or example that tells more about the main idea
proof from the text
one case that shows something
a true piece of information
1. Discover: Why we need sleep
Sleep is important for children. When we sleep, our bodies rest and grow. Sleep helps us think clearly at school. Children who sleep well are in a better mood. Most children need about ten hours of sleep each night.
Think: Which facts support the idea that sleep is important?
2. Understand: Details that support
Idea 1: Details and evidence
Supporting details are facts or examples that explain the main idea. They are evidence from the text.
Idea 2: Finding them
Ask: What does the text say about the main idea? Here: bodies grow, we think clearly, we are in a better mood.
Idea 3: Check fit
A detail must connect to the main idea. A fact about football would not fit a text about sleep.
3. Worked examples
Example 1 (I show you): Find
Which detail says why sleep helps school?

Courseversity badge thresholds (overall quiz score): Gold = 90–100%; Silver = 80–89.9%; Bronze = 70–79.9%. A badge is never a full record of progress.
If a learner struggles
- Find the misconception: Adding details that do not fit. Check they connect.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Use a graphic organiser.
- 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 finds details that support the main idea. You do not need to be an expert to help.
- Ask: What does the text say?
- Read together.
- Praise evidence.
- 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.
