Reading and writing numbers up to 100 means being able to say, recognize, and write numbers from 0 to 100 using both digits and words.
Always remember: numbers can be written in two ways—using digits and using words.
To identify and write numbers, look at the place value of each digit. The tens place shows groups of ten, and the ones place shows how many single units are left.
Break numbers into tens and ones to make reading and writing them easier.
When writing numbers in words, always use correct spelling and a hyphen between the tens and ones for numbers greater than twenty and less than one hundred.
Do not use the word “and” when writing whole numbers. For example, write forty-two, not forty and two.
We use numbers every day for counting, measuring, and comparing amounts. Being able to read and write numbers helps us solve problems in the real world.
Numbers are all around us—in calendars, clocks, money, and more. Practice by reading numbers you see every day.
