This lesson focuses on Comparing Numbers: use more than and fewer than to compare two groups.
Use more than and fewer than to compare two groups.
Key ideas
Number order
Numbers grow by one each step, so a number further along in the count is always larger: 9 comes after 7 and is bigger.
One-to-one counting
Touch or point to each object once and say one number name each time. That way no object is missed and none is counted twice.
Key term — Digit: Any of the symbols 0 to 9 used to write numbers. The number 42 uses two digits.
Write the numbers 8, 3, 11, 5 from smallest to largest.
3, 5, 8, 11.
Answer: 3, 5, 8, 11.
- Thinking 9 is bigger than 11 Compare by seeing which comes later in the count, not by how big the digit looks.
- Saying number names out of order Practise the sequence aloud until it is automatic, like the words of a song.
Practice
14, 15, 16, 17, 18, 19, 20.
29, because 29 comes after 25 when counting.
30 — counting back one from 31 gives 30.
