Overview
Many young children come to school with a natural curiosity
about the environment around them and how everything in it works. This
curriculum unit on machines-- and how they help us in our daily lives-- is
developed for the pre-kindergarten level supporting the English Second Language
learners. Our unit “Machines and Us” is based on a thematic approach
to teaching and learning. This unit is integrated with multiple discipline areas
- literacy, math, social studies, science, and technology. This unit utilizes
strategies that engage children to do meaningful activities in each of the work
centers for independent exploration. It helps to motivate children to acquire
information, ask questions, and research concepts. The purpose of this unit is
to provide opportunities for children to explore with machines and to discover
how these machines work. Young children, including second language learners, are
fascinated by the different sizes, shapes, and the functions of machines.
Children will develop visual-spatial concept and problem solving skills by their
increased awareness and understanding of how machines work.
It is extremely important in the early childhood environment
to introduce this unit to girls as well as boys. The traditional social
expectations have been for boys, not girls, to play and tinker with machines. If
a unit of study focusing on machines is part of the early childhood curriculum,
more girls, along with boys, will be given the opportunities to develop a higher
comfort level with working with machines and technology. They will learn
that it is very important, and possible, for everyone in society to learn and
understand the mechanics of machines and technology.
This graphic organizer demonstrates the various components of this thematic unit.

design their own machines.
h) To help children to develop a comfort level in working with
computer technology.
