Description

Course Description Icon

In this lesson we learn how we can encode an image as pixels in the form of hexadecimal. Students will use their knowledge of Hexadecimal, binary and decimal conversions to encode an image into a hexadecmial value. 


A Summary

Minimum Grade Best for students 3rd grade and up
Complexity Level Medium
Length 20 minutes / Class
Subject Area Hexadecimal, binary and decimal conversions to encode an image

Target Audience

We think this material can be understand by students as young as 3rd  grade.

Testing?

YES.  Just like most of our micro-lessons, there will be a test as the lesson goes along however this lesson includes activities to complete.

You will be given a set of data (hexadecimal) and will need to decode the hexadecimal data to determine what the data is representing and you will be given an image and will be asked to encode the image into hexadecimal (encoding and decoding) To acheive success in this lesson you will need to complete the in-lesson tasks.
