Lesson Plan

Overview

Students will learn the definition of input/output as it relates to computing and will use the Micro:bits to demonstrate various examples of inputs and outputs.

ASSESSMENT PRE/POST-TEST

In programming, what input would cause a computer to say Hello? List examples of input devices. List examples of output devices. What is I/O? The communication between an information processing system, such as a computer, and the outside world, possibly a human or another information processing system is referred to as the ___________________

OBJECTIVES

Define Input/output Write a program for the micro:bit (input) that creates an output Demonstrate the use of input to create an output

CATCH/HOOK

Show video on Input and Output devices https://study.com/academy/lesson/i-o-control-methods-types-explanation.html Hold up various items used for input and output and ask students to identify which they are? Mouse, keyboard, screen, printer, stylus, etc

Whole Group - Teacher Led: Start with Hook - Show the Youtube video on Input and Output devices Individual - Students watch Edpuzzle over I/O and Micro:bits and answer questions https://edpuzzle.com/media/62d073d9fd26d740d9dd512c
Learn about the Micro:bit by navigating to the website: https://microbit- micropython.readthedocs.io/en/latest/tutorials/io.html Work in Pairs: Look at the Micro:bit and find each of the input/output pins (or I/O pins for short) 0, 1, 2, 3V and GND Discuss what the V and the GND stand for USe https://microbit.org/get-started/first-steps/introduction/ as a resource Whole Group - Teacher Led Reflect, answer questions Teacher led and Work in Pairs Navigate to https://makecode.microbit.org/# Direct students to Start new Project Give Whole class instruction on Inputs….show examples Allow students time to work with Inputs (Button A pressed) and Output (Music Played)

** Optional - Have students hook up Microbit with speaker and download program to it

REVIEW

What is an I/O? (Input/Output) Typing a computer program is input or output? (Input) Music playing through a speaker is input or output? (output) The LED lights on a Micro:bit are input or output? (output) The pins (0,1, 2, 3) on the Micro:bit are input or output? (input) Pushing the button A on the Micro:bit is input or output? (input) Your computer monitor is input or output? (output)
