- Convert decimal numbers to binary numbers
- carry over
- place values
First watch the following videos to understand the basic of binary number systems.
Making a binary glove
- a white glove

Step 2. Flip the glove over and write 1s on the tip of all your fingers and write 0 on knuckle Right an arrow from pinky to thumb
This side of your hand is the binary side.
Count the numbers 0-31
Step 1. Count the number from 0 to 31 with the binary glove.
Step 2. Count the number from 0 to 31 wihtout the binary glove.
