Research shows student achievement increases when children compare and contrast using comparative thinking. Starting at a young age, we can nurture children’s comparative thinking, ratcheting up the level of difficulty as they grow in age and developmental ability. Since we love books here at Brightly, let’s look at using books combined with Thinking Maps and graphic organizers to practice this important skill.

But First, Define Terms

It’s essential that kids know what we mean when we ask them to compare and contrast. Compare is to find similarities. Contrast is to find differences. Believe it or not, kids will usually need to be reminded of these terms every year.

What Kinds of Stories Can We Compare and Contrast?

Compare-and-Contrast Thinking Maps

Now that you have ideas for what to compare, it’s helpful to provide kids with comparative structures to mitigate their thinking. Use these ideas when you work with children using the book-related comparative ideas above.

A Venn Diagram, T-Chart, or Double Bubble Map can all help children organize their thinking visually. As always, model how to use each of these before students work on them independently. How many times you model this and what organizer you choose will depend on your students’ levels and needs.

T-Chart

A two-column T-Chart might be the easiest compare-and-contrast graphic organizer. One way to use a T-Chart is to put the two things you are comparing for the title then label each column “Same” and “Different.” You’ll then list what’s the same in one column “Dogs and cats are both pets” and what’s different in the other “Dogs are canines; cats are felines”.

Alternatively, you can put the topics you’re comparing in their own columns. Here’s an example from an elementary classroom using the book No, David! by David Shannon. The “Yes” behaviors for David are in one column with the “No” behaviors for David in the other.

Venn Diagram

A Venn diagram is another classic but helpful graphic organizer when comparing two concepts or things. Kids draw two overlapping circles. Each circle is labeled for the idea or thing it represents. For example, “Trains” for one circle and “Sharks” for the other.

The overlapping part of the circles, the middle, is for listing the similarities between the two things. The outside circles are for listing the differences. See an example here.

Double Bubble Map

Double Bubble Maps are research-based Thinking Maps specifically designed for comparing and contrasting. Kids write the two things they’re comparing in large bubbles, or circles. Similarities between these two things are listed in circles between the two. Differences are listed in circles extending toward the edges of the paper. See an example comparing bats and spiders here.
