Charlotte's Web Synonym Activity

Spinning Webs of Words

Inspired by Charlotte's Web, this activity helps students practice synonyms in a creative way. It doubles as a Halloween activity and produces a beautiful bulletin board display.

Instructions
  1. Print a different spider web for each student.
  2. Students write synonyms for the provided word on the lines below the web. This is a great time for the teacher to check for spelling and accuracy.
  3. Once the teacher verifies the words, students rewrite them in the blank spaces on the web.
Extensions
  1. Have students order their synonyms by shades of meaning before writing them on the web — connecting this activity to the shades of meaning work on the previous page.
  2. Have students list antonyms for the word on the back.
Finishing Touches

Cut the bottom section off directly above the line and display pages on a bulletin board titled "Charlotte's Web of Words" or "Synonym Webs." Spider webs on odd and even-numbered pages are rotated differently, creating a visually interesting display.

Analogies & Digital Resources

Analogies extend synonym and antonym work into higher-order thinking — students must understand the relationship between words, not just their meanings in isolation.
