TEACHER MS. ROBO KITTY ON: Binary Numbers

“The rise of computers and computer graphics has increased the need for knowledge of how to work with different (non-decimal) base systems, particularly binary systems (ones and zeroes)” (www.purplemath.com/modeuls/numbbase.htm).

One parent introduced third graders to binary numbers after teaching them a class about the powers of two.  He used 27 sticky notes on a whiteboard broken into powers of two.  You can check out his presentation at www.exploringbinary.com/how-i-taught-third-grades-binary-numbers.

See www.ducketers.com for a short, simple, and sweet module on binary numbers in their Kids Math section.

A wonderful hands-on activity to teach binary to your students is to make binary bracelets.  Use black and white beads to have your students string a bracelet with their name.  YouTube has several videos that you can show in conjunction with making binary bracelets.  Check out youtube.com
