lesson
Read the value, not just the digit
1 · Learn
In 608,045, the 6 represents 600,000, the 8 represents 8,000, the 4 represents 40 and the 5 represents 5. The zeros hold the ten-thousands and hundreds places.
Group digits in threes to read large numbers: six hundred and eight thousand and forty-five. Compare from the largest place where the digits differ.
2 · Worked example
I compare 608,045 and 680,045. The hundred-thousands match, but 8 ten-thousands is greater than zero ten-thousands, so 680,045 is larger.
3 · Your turn
Write 450,307 in expanded form. Find 10,000 more than 389,500.
Check your answer
400,000 + 50,000 + 300 + 7; 399,500.
4 · Apply your learning
Use a labelled place-value chart to make and order numbers, then count forwards and backwards in 10s, 100s, 1,000s and 10,000s from non-zero starts.
Adult guidance and safety
Model the calculation or measurement before relying on a procedure. Explain estimates, units and checks. Use a ruler/protractor and suitable diagrams where needed; text examples alone do not establish practical skill or fluency.
