WALT & Success Criteria

WALT: We are learning to round numbers to the nearest ten and hundred using a number line.

Success Criteria:

I can identify the two nearest multiples of ten or hundred on a number line.
I can decide if a number rounds up or down based on its position on the number line.
I can explain my rounding answer using the number line.

📚 Part 1: Guided Practice (Choose the best answer)

1. Round 47 to the nearest ten.

2. Round 68 to the nearest ten.

3. Round 350 to the nearest hundred.

300

350

400

4. Check all that apply: Which statements are true about rounding on a number line?

If a number is less than halfway, it rounds down.

If a number is halfway or more, it rounds up.

Numbers always round to the nearest hundred, never ten.

5. Explain in one sentence why 47 rounds to 40 when using a number line.

Support & Differentiation

Dyslexia-friendly options: Use large, well-spaced number lines, high-contrast colours for key points, and counters to mark positions.

For learners needing support: Use a physical number line and move a token to see 'before' or 'after' the halfway point (e.g., 45).

Extension: Try numbers closer to the halfway point (e.g., 145, 148) and explain your choice using place-value language. You might also round numbers up to 1,000.
