Frog Life Cycle Worksheets & Printables

These worksheets will help students learn about frog metamorphosis from egg to tadpole to adult frog.

  • Create a frog sensory bin using a sand or water table. Use blue water beads and a few rocks as the base. Add green gems to represent lily pads. Add frog figurines and allow children to play with the frogs in their new habitat!
  • Create an anchor chart using cards to represent each stage of the frog life cycle. Use tape or velcro on the back of each card so children can practice placing them in the correct order.
  • Use books in your lessons about frog life cycles. Consider picture books that can be read aloud to children and more research-based books for older children.
  • Visit a pond to look for frogs and frog eggs.

Frogs begin as eggs. Female frogs lay as many as 4000 eggs at a time. Their eggs are black and white, jelly-covered, and very tiny. The female frogs lay their eggs in ponds and the eggs float on the water in groups called “egg masses.”

In the next stage of the life cycle, tadpoles hatch from the eggs. This happens about six to 21 days after the eggs were laid. When they hatch, tadpoles look like fish because they do not have any legs. They have gills so they can breathe underwater and are developing lungs, which will one day allow them to breathe on land when they become frogs. Tadpoles swim around and eat things like plants and algae.

After six to nine weeks, the next stage of the life cycle begins. During this stage, the tadpoles grow legs. They have two hind legs, which allow them to jump around in the water. The tadpoles are starting to look more like frogs now. They still have a long tail though.

After developing legs, the tadpoles begin the stage of becoming froglets. This happens about 12 weeks into the life cycle. Their tails get much shorter and they grow two front legs. Their eyes also start to bulge. The froglets are able to jump out of the water and onto land. They are still much smaller than adult frog during this stage.

The last stage in the life cycle is becoming an adult frog. During this stage, the froglets lose their tails completely. They also start eating insects instead of plants and algae. Adult frogs can lay eggs on the water, which starts the life cycle all over again!
