1st Grade Two-Circle Venn Diagram Worksheet: Count the Shapes in Each Set

Draw two hoops on the floor so they overlap, and a six-year-old will happily stand right in the middle, inside both at once. This 1st grade two-circle Venn diagram worksheet puts that middle on paper. Ten small diagrams fill the page, each with a circle A and a circle B that cross. Colored shapes sit in each part: blue dots and green squares, pink hearts and yellow stars, red triangles and orange circles, and more. Next to each diagram, two questions ask how many shapes are in one set, or in both. Your child counts, then writes the number in the bubble. A second page gives the answer key.

Why the middle part is the whole lesson

A Venn diagram shows two sets at once, and the shapes in the overlap belong to both. That is a big idea for a young child: one object can fit two groups at the same time.

The page asks three kinds of questions. Some ask about one set, some about the middle, and some ask about one color or one kind of shape. So your child has to read the question, then decide which part of the drawing to look at.

This is sorting shapes, turned around. Instead of putting shapes into groups, your child reads groups that are already made. Logic and counting work together here.

At the table: shapes inside both circles

Start with the first diagram. Ask, "Which shapes are inside both circles?" Let your child trace the middle part with a finger.

The middle is where most counts go wrong. A child may count those shapes twice, once for each circle, or skip them. Instead of correcting, try, "Is this square in A, in B, or in both?" Then point to one shape at a time.

The word only needs care too. A question about set A only is about the part of A outside the middle. Ask your child to cover circle B with a hand and look at what remains.

Finally, some questions ask about one color, like the blue shapes. A light dot on each one keeps the count honest.

Hoops, socks and sorting at home

Venn diagrams come alive with real objects. Lay two loops of string on the floor so they cross, then sort toys into "red" and "has wheels." A red car goes in the middle. Also, sort the laundry: one loop for socks, one for white clothes, and white socks in between.

Mouse Shapes by Ellen Stoll Walsh pairs well with this page. While you read it, stop on a page and sort the paper shapes the mice use into two groups, by shape and by color.

These small sorts teach that a thing can belong to two groups. When the page is done, go over each answer together and name the effort: "You thought about the middle. That is careful sorting."
