Lesson 4 of 186
Concept
Number words tell place value: - "forty-two" means 4 tens and 2 ones -> 42 - "sixty" means 6 tens and 0 ones -> 60
Helpful pattern: - twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety - Add ones after a hyphen: twenty-one, thirty-six, ninety-nine.
If you hear just one word like "seven," write 7. If you hear a tens word and an ones word, combine them.
Try it
Write the digits: 1. thirty-four 2. fifty 3. eighty-two 4. nineteen 5. sixty-seven
Write in words: 6. 41 7. 90 8. 58
