What K-3 vocabulary worksheets are on ClassWeekly?
ClassWeekly vocabulary worksheets build word knowledge directly, separately from reading comprehension passages: synonyms and antonyms, homophones and homonyms, compound words, multiple-meaning words, and context clues. There are 124 vocabulary worksheets for Kindergarten through 3rd Grade, each aligned to a Common Core language standard.
Vocabulary used to live as a Reading subtopic on this site. It's its own subject now, because word knowledge is its own skill, not just a side effect of reading practice. A kid can decode a sentence perfectly and still not know what half the words in it mean.
Kindergarten starts with themed practice words (animals, colors, the five senses, school and home) alongside sight words, compound words, and question words. 1st and 2nd grade add context clues, homophones and homonyms, and word-practice formats like scrambles and missing-letter puzzles. 3rd grade moves into idioms, similes, and alphabetizing on top of everything before it.
Every worksheet ties to a specific Common Core ELA standard (the L strand, mostly), and the code is printed on the page so you can check alignment yourself. Pick your child's grade, then narrow down by the specific skill they're shaky on: a kid who mixes up "their" and "there" needs homophone practice, not another round of generic vocabulary review.
