Three places after the point
1 · Learn
One thousandth is 0.001. Ten thousandths make one hundredth, and one hundred hundredths make one whole. In 2.347, the digits after the point represent three tenths, four hundredths and seven thousandths.
Read each place rather than treating 347 as a whole-number part. 0.347 is 347/1000; it is smaller than one.
2 · Worked example
I compare 0.507 with 0.57 by writing 0.57 as 0.570. Seven hundredths are greater than zero hundredths, so 0.570 is larger.
3 · Your turn
Write 0.608 as a fraction with denominator 1,000. Order 0.608, 0.680 and 0.068.
Check your answer
608/1000; 0.068, 0.608, 0.680.
4 · Apply your learning
Place the values on a labelled chart and explain the role of each zero.
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.
