The first full week in October is World Space Week! These worksheets focus on matching space themed vocabulary words to their definitions. There are four different worksheets for the same words and definitions, allowing you to use them as pretests, post-tests, and practice pages. There is a matching page for all 24 words, a matching page for the words split into 12 word half pages, a fill-in worksheet with a word bank for all 24 words, and a fill-in page for the words split into 12 word half pages. Answer sheets are included for each worksheet. These vocabulary words are the same ones used in the space themed vocabulary cards and the space themed vocabulary bingo game.
