Let your kids practice and build skills for future Venn Diagrams with this PDF worksheet. They'll trace lines to match and group animals, and learn the differences and similarities of animals by categorizing with pictures and words. Plus, it's a great way to develop fine motor skills.
Look at the animals with your child. Ask them to name them, then sort them by type (e.g. lions and bears). Next, help them sort by size, tracing the dotted lines. This will teach them sorting skills.
