Computers Then and Now

Overview

This 45-minute lesson introduces Kindergarten students to the concept of how computers have changed over time. Using simple explanations, engaging storytelling, and hands-on activities, students will explore the evolution from old computers to devices they recognize today. The lesson strongly aligns with Common Core State Standards in English Language Arts to build foundational literacy while connecting to a STEM-related theme.

Learning Objectives

By the end of this lesson, students will be able to:

• CCSS.ELA-LITERACY.RI.K.1: Identify the front cover, back cover, and title page of a book about computers.
• CCSS.ELA-LITERACY.RI.K.3: Describe the connection between events in a simple text about computers and technology.
• CCSS.ELA-LITERACY.SL.K.2: Confirm understanding of a text read aloud by asking and answering questions.
• Demonstrate awareness of how computers looked a long time ago compared to today.
• Use basic vocabulary related to computers (e.g., old, new, big, small, screen, keyboard).

Materials Needed

• Picture book or large illustrated poster about old and new computers (simple)
• Printed images of early computers (e.g., room-sized, big monitors) and modern devices (tablets, laptops)
• “Then and Now” sorting cards (pairs of old vs. new computer images)
• Whiteboard and markers
• Crayons and paper for drawing
• Computer-shaped cutouts for group activities
• Timer or visual countdown
• Comfortable seating arrangement for circle time and group work

Lesson Activities

1. Introduction & Story Time (10 Minutes)

• Attend to Story Structure (RI.K.1, RI.K.3)
• Gather students in a circle and show the cover of the picture book or poster. Read aloud a brief, age-appropriate story about the journey of computers from "big and slow" to "small and fast." Use simple sentences and point to pictures.
• Ask questions such as: "What do you think this machine is?" and "How is this computer different from the one we use today?"
• Reinforce vocabulary by emphasizing words like “old,” “new,” and “big.”

2. Visual Sorting Activity - Then and Now (10 Minutes)

• Apply Knowledge & Compare (RI.K.3, SL.K.2)
• Show printed images of old computers and modern devices.
• Distribute cards to pairs or small groups of students.
• Ask students to sort pictures into two piles: computers used a long time ago and computers used now.
• Circulate and ask guiding questions: “Why do you think this one is old?” “What is different about this tablet?”
• Allow groups to briefly explain their sorting to the class, promoting verbal expression and listening skills.

3. Group Discussion & Question Time (5 Minutes)

• Engage Listening and Speaking (SL.K.2)
• Have a brief interactive chat. Let students ask questions about computers.
• Clarify and confirm understanding by rephrasing answers with simple terms.
• Use a visual cue (such as a “talking stick”) so only one child speaks at a time, helping with turn-taking.

4. Creative Drawing and Storytelling (15 Minutes)

• Express Understanding Through Art and Words
• Hand out paper and crayons. Invite students to draw their own version of a "computer of the past" or a "computer of the future."
• After drawing, encourage them to share one sentence about their picture with a partner or small group (supported by prompts like “My computer is ___ because ___”).
• This allows practice with vocabulary, narrative skills, and fine motor development.

5. Closing and Review (5 Minutes)

• Recap the main points: “Computers were big and slow before, but now they are small and fast.”
• Ask quick review questions: “Which computer is bigger?” “What do we use computers for today?”
• Praise effort and curiosity.
• End with a fun “clap if you learned something new” activity to celebrate participation.

Assessment & Reflection

• Informal Formative Assessment:
  • Observation during sorting and discussion activities for understanding of “old vs. new.”
  • Listening to students’ sentence sharing about their drawings to assess vocabulary comprehension.
• Checklist for Teacher:
  • Can the student identify and sort old and new computers?
  • Can they respond to simple questions about the story?
  • Did the student participate in the speaking and listening components?

Teacher Tips and Differentiation

• Use clear, simple language and concrete examples.
• Provide visual supports for all steps, as K students benefit greatly from pictures and hands-on materials.
• For students who need extra help, assign peer buddies during group activities.
• For advanced learners, encourage them to name more computer parts (mouse, keyboard) and think of other devices that use computers.
• Include movement breaks if attention wanes—use a quick “robot dance” to connect movement with the computer theme.
