gap
a missing step or piece of information

1. Discover: How do plants make food?

Text A: Plants take food from the soil, like animals eat. Text B: Plants make their own food by photosynthesis. Leaves take in sunlight, water from the roots and carbon dioxide from the air. They make sugar, and release oxygen.

Text A is short but inaccurate: plants make food in their leaves. Text B is accurate, clear and complete, with all steps and no gaps.

Think: Which explanation is better and why?

2. Understand: Is this explanation good?

Idea 1: Accuracy

Is it correct? Check against a trusted source.

Idea 2: Clarity

Is each step clear and in a sensible order?

Idea 3: Completeness

Is it complete, or is there a gap? Is there supporting evidence?

Remember: A good explanation is accurate, clear and complete, with no gaps and with evidence.

3. Worked examples

Example 1 (I show you): Accurate

Which text is accurate?

  1. B.

Answer: Text B

Example 2 (We do it together): Wrong

What is wrong with Text A?

  1. Food.

Answer: plants make food in leaves, not take it from soil

Example 3 (You try): Complete

Why is Text B complete?

Show the steps and answer
  1. All steps.

Answer: it names sunlight, water, carbon dioxide, sugar and oxygen

Did you know?

Old explanations about nature were often corrected when people tested them.

Why this matters

Evaluating explanations helps you choose reliable information.

4. Explore: Rate it

Evaluate two explanations.

Mastery and remediation

Objective Bronze (Developing) Silver (Proficient) Gold (Advanced)
O1 Check accuracy Shows this with help from an adult or a picture Does this independently and explains how they know Explains it clearly and uses it in a new situation
O2 Check clarity Shows this with help from an adult or a picture Does this independently and explains how they know Explains it clearly and uses it in a new situation
O3 Check completeness Shows this with help from an adult or a picture Does this independently and explains how they know Explains it clearly and uses it in a new situation

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

  1. Find the misconception: Rushing without checking. Slow down and check your work.
  2. Explain another way: use real objects, pictures or actions first, then words.
  3. Show a simpler example: Re-read the examples slowly and use the sentence frames.
  4. Guided practice: work through one example together and let the learner try the next one.
  5. Reassess: use the quiz again or the worksheet.
  6. 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.
