The teaching of two-digit numbers to children should be an interesting and interactive process.
We can help children develop a sound foundation for numbers through hands-on manipulatives, measuring activities, place value concepts, and decomposition strategies.
Through these skills, they will be better placed to manage the world of mathematics and develop a strong mathematical attitude for the future.
Two-digit numbers are those with two digits, beginning with the number 10 and ending with the number 99.
Examples: 13, 41, 60, 82, 96
There are only two place values – the units place and the tens place for the 2 digit numbers.
2 digit numbers can be expressed as words, expanded forms, or as numerals.
Example:
Numerals: 74
In words: Seventy-four
Expanded form: 70 + 4
