Teacher: Semidei (Militza), Roldan (


IMPORTANT TEACHER’S MESSAGE: Although we strongly encourage the practice of skills at home, these ideas are only suggestions to provide you with resources and help you maintain a routine during these unprecedented times.  Please complete with your child only what works for your family’s needs. We appreciate all of your effort!


Lets learn a little about the life cycle of a butterfly.


A butterfly lays  eggs on a leaf. The eggs are small and round. At first the eggs are yellow and they slowly turn brown.


After about 5 days, a caterpillar hatches from the egg! It is black when it hatches.

The caterpillar is very hungry and it eats all the time. It eats the leaves on which it hatches.  They eat leaves and flowers till they become bigger and bigger.

As they grow bigger their skin keeps falling off and they get new skin and it changes from black to green.


When the caterpillar is fully grown it hangs upside down and wraps itself in a cocoon, like a blanket.

The cocoon is called a pupa or chrysalis.  The pupa is green.


The caterpillar starts changing inside the pupa. It slowly transforms into a butterfly!

After some days a beautiful butterfly comes out!!

At first the butterfly is small and tired. It flaps its wings to exercise them and learns to fly. Soon it is ready to fly!
