A main idea and details chart shows the hierarchical relationship between major concepts and their subordinate elements. These puzzles below can be used as an introduction to the main ideas. Students will need to pull out the main idea circles and then read the details to figure out which main idea each goes with. The first set contains a word for the main idea and pictures that support the word. The second set contains no pictures, and the reading difficulty increases with each puzzle. Each set contains the color pages first, with black and white versions at the end. Use EdrawMax Online to create a main idea puzzle diagram for your classes.
