How it works

Choose a Venn diagram or the cut-and-sort pack. Start from a preset (two characters, two animals, fractions and decimals, then and now) or type a title and a label for 2 or 3 circles. For the pack, type each item with its circle, such as “lay eggs in water: both”.
Set the look. Writing lines 3/8 in [10 mm] or 1/2 in [13 mm] apart inside the circles, an outline or a light tint per circle in 16 colors (or any color), with dots and stripes so the overlap shows without color, a sentence frame under the diagram, and a NAME / DATE line. The circles are always the largest that fit the page.
Download the PDF and print. The pack prints the mat, the cards mixed up so they are not in their groups (a word, or a word with a picture box) and the answer key last, counted on the button (“2 pages + key”). Portrait or landscape, US Letter (8.5 × 11 in) or A4 [210 × 297 mm]; free, no sign-up, no watermark.

Tips for Venn diagrams

K–2 teachers: the cut-and-sort pack with picture boxes makes a science or math center: children cut, sort and glue, then you check against the key. Print the mat on cardstock to reuse it.
Teachers, grades 3–8: compare two characters with 3/8 in writing lines and the sentence frame, so the diagram turns into a paragraph.
Science and social studies teachers: three circles compare three characters, countries or animals; type “all” for what all three share and “frogs and toads” for a pair.
Color-blind students and gray printers: choose Tint and pattern; the dots and stripes still tell the circles and the overlap apart.
Parents and homeschoolers: “Then and now” is a quick history talk at the kitchen table; add your own family items to the list.
Writers, from diagram to paragraph: sort the notes into a 2 column notes template, one column per side, before writing the paragraph.
