Words to know
a short retelling of main points
the most important point
an important fact that supports the main idea
to say something in your own words
1. Discover: The water cycle
Water on Earth moves in a cycle. The sun warms water in rivers and seas, and it rises into the air as vapour. This is called evaporation. High in the sky, the vapour cools and forms clouds. This is called condensation. When the clouds become heavy, rain falls. This is called precipitation. The rain flows into rivers and seas, and the cycle begins again.
Think: Can you tell the cycle in two sentences?
2. Understand: Short informational summaries
Idea 1: Main idea
The main idea: water moves in a cycle from earth to sky and back.
Idea 2: Key details
Key details: evaporation, condensation, precipitation, collection in rivers and seas.
Idea 3: Summary
A summary: Water evaporates, forms clouds by condensation, falls as rain, and flows back to rivers and seas. Use your own words (paraphrase).
3. Worked examples
Example 1 (I show you): Main idea
What is the main idea?
- First sentence.
Answer: water moves in a cycle
Example 2 (We do it together): Key details
Name the key stages.
- Three named processes.
Answer: evaporation, condensation, precipitation
Example 3 (You try): Summary
Write a one-sentence summary.
Show the steps and answer
- Join main idea and details.
Answer: Water rises as vapour, forms clouds, falls as rain and returns to rivers and seas.
Did you know?
The same water has been moving around the Earth for millions of years.

If a learner struggles
- Find the misconception: Rushing without checking. Slow down and check your work.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Re-read the examples slowly and use the 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 practises a key Grade 3 English skill with clear examples and a quiz. You do not need to be an expert to help.
- Listen while your child explains the idea.
- Ask for one new example.
- Praise effort and careful work.
- 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.
