This week it was all about learning from our mistakes and trying to find solutions to them. The grade fours were back creating mazes so they could complete a code for the bee bots to move around the maze. In other words we were debugging…

While they were working they were given a couple of questions to consider…

What did you find the most difficult?

  • coding

How did you try to fix this?

  • coding in small steps
  • changing the walls to suit the bee bots movements
  • fixing the maze so the track is wider
  • making smaller and less complicated mazes

What did you learn about coding?

  • It isn’t as easy as it sounds
  • it doesn’t always work the first time
  • it’s a set of instructions
  • you need to be very precise
  • it takes time to get it right
  • could need to test and retest
  • code in small steps

Success is SWEET 🙂 Well done Aiden, Jyotsna and Josh.

BeE-bOt MaZeS…

Our second CODING challenge involved bee-bots, cotton buds and a ruler.


The challenge was to build a maze using cotton buds and program a bee-bot to travel through the maze. Of course there were conditions:

  • the maze needed an entry and exit point
  • only one box of cotton buds (200 tips) could be used
  • the maze had to wide enough to fit a bee-bot through
  • a code had to be written for the bee-bot to get it from the start to the finish of the maze

img_0856We revised what we learnt from the previous week and discussed how precise coding is and how our algorithms needed to be simple and clear. We also talked about testing and retesting to iron out the bugs…

So mazes were restructured and rebuilt, new instructions were added and others deleted, in order to get the bee-bot from one end of the maze to the other.

This created great excitement, discussions and teamwork…

Bee Bot Fun…

Bee-BotWhile each grade four class rotated through the Kitchen, the other grade four classes were having some fun with the Bee Bots.

Bee Bots are a robot designed for children. They are easy-to-operate, and the little robot is a perfect tool for teaching sequencing, estimation and problem solving. Its directional keys are used to enter up to 40 commands, which can send the Bee-Bot forward, back, left, and right. Pressing the green GO button starts Bee-Bot and it blinks and beeps at the conclusion of each command to allow children to follow the Bee-Bot through the program they have entered and then confirms its completion with lights and sound.

We asked the grade fours to choose one of the following challenges to complete. They were all very excited and couldn’t wait to start.

Challenge One

  • Make a Bee Bot Maze with Unifix Blocks.
  • Program the Beebot to travel through it.

Challenge Two

  • Make a Bee Bot trail using MAB. Include some tunnels.
  • Program the Beebot to travel through it.

Challenge Three

  • Make a Slalom course for your Bee Bot.
  • Program the Beebot to travel through it.

Challenge Four

  • Draw a set of eight animal cards. Each on a of 25 x 25cm  square of cards.
  • Tape your cards under the clear plastic grid.
  • Create a set of “Who Am I?” cards to match your animals. Ask other students to solve the puzzles and program the Bee Bot to travel to the correct square.

With the challenge set the grade fours set about creating trails and mazes for their Bee Bot to negotiate. The library was taken over, organised chaos happened, problem solving skills were needed, smiling faces and triumphant squeals could be heard as groups succeeded. It’s definitely an activity we could repeat 🙂
