SLIDE 2

A simple example puzzle

12 1100 3 0011 6 0110 9 1001

  • Fill the grid using only

powers of 2 (1,2,4,8)

  • Horizontal (vertical)

blocks must add to the number on the left (above)

  • Fill in the binary of the

answers too

slide-3
SLIDE 3

A simple example puzzle

12 1100 3 0011 6 0110 9 1001

  • Each number has a

unique sum

  • Work values out from

the intersection of sums

  • 3 = 1 + 2
  • 9 = 1 + 8

SLIDE 4

A simple example puzzle

12 1100 3 0011 6 0110 9 1001

  • 3 = 2 + 1
  • 6 = 2 + 4

The binary tells you the numbers! 0011 = 0010 + 0001 3 = 2 + 1

SLIDE 5

A simple example puzzle

12 1100 3 0011 6 0110 9 1001

  • 12 = 8 + 4
  • 6 = 2 + 4
  • 9 = 8 + 1

Now you have the basics, do a harder version

Extension Activity

  • Get the students to

invent their own based on blank grids

  • They must check it is

solvable!

  • Then create ones

from a blank sheet of squared paper

Summary

  • Learn fundamentals of binary and logical

thinking

  • Lots of practice at binary
  • more fun than lists of binary-decimal

conversions to do

  • also focusses on underlying construction
  • Puzzles are a good way to explore and learn

many computing and computational thinking ideas
