Group Challenge


In small groups, students race to complete the challenge the fastest. 
  1. Give out the challenge cards (Stage 1 Creating a decimal number from a binary number – challenge cards pdf).
  2. In teams, students work together to convert five binary numbers into decimal numbers.  When complete, the group shouts ‘stop’ and receives a time.
  3. Students swap responses with another group and correct answers. You could complete a short reflection here and ask how successfully the teams collaborated. Did everyone participate equally? Did they devise a strategy to complete this challenge?
  4. Alternatively use these online binary cards for a binary number of 8 digits (byte) provided by CS unplugged. As a starting point you may want to use 5 online binary cards which make it easier to introduce the concept.
