Skill: Reading and writing the number words from eleven to twenty
Teaching tips and what to try next
Right for first graders who already read and spell the words in Number Words 0-10 and know that teen numbers mean ten and some more. Writing each word on a card and sorting the cards into "sounds like its digit" and "has to be memorized" piles helps the tricky ones stick. Strengthen the tens-and-ones idea with Teen Numbers: 10 and Some More or see 1.NBT.B.2.
10 versions, each with its own answer key
Same skill and layout, a fresh set of problems in every version, so children can keep practicing without repeating a page. Problems are not repeated between versions unless a skill has only a small number of possible problems (for example, the addition facts within 10).

About this worksheet
The number words from eleven to twenty are some of the hardest to read and spell. Eleven and twelve sound nothing like one and two, and words like fifteen and thirteen hide the five and the three inside them. This first-grade worksheet practices reading and writing these words in two ways.
Part A shows six number words in large print, and children write the matching number in the box. Part B shows six pictures made of two ten-frames: a full frame of ten dots and a second frame with the extra dots. Children count the dots and write the number word on the handwriting lines. A word bank at the top of the page lists all ten number words from eleven to twenty, so children can check their spelling as they write. Each of the ten versions mixes the numbers in a new way and comes with its own answer key.
How to use it: say the words slowly together and listen for the clues. Sixteen, seventeen, eighteen and nineteen all start with the sound of a number from 6 to 9, and the "teen" ending means ten more. Then point out that eleven and twelve are different and simply have to be learned. For Part B, encourage your child to see the full frame as ten right away and count on from there, like "ten, eleven, twelve."
The answer key shows every answer. For the first number words, try our Number Words 0-10 worksheet. To build teen numbers as ten and some more, try our Teen Numbers: 10 and Some More worksheet.
