lesson
Hundreds, tens and ones
1 · Learn
Ten tens make one hundred. In 472, the 4 represents 400, the 7 represents 70 and the 2 represents 2.
A zero can hold a place. In 405 there are four hundreds, no tens and five ones. Leaving out the zero would give 45, a different number.
2 · Worked example
I build 306 with three hundreds and six ones. I keep a zero in the tens column.
3 · Your turn
Write the number with five hundreds, no tens and eight ones. What is the value of its 5?
Check your answer
508. The 5 represents 500.
4 · Apply your learning
Build or draw 360, 306 and 630. Explain the value of every digit.
Adult guidance and safety
Use objects or a drawn model before relying on a rule. Explain each step, check the units and revisit with varied examples. An adult can read the instructions without supplying the answer.
