Algorithms

I can explain what an algorithm is I can follow an algorithm I can write an algorithm I can improve my algorithm

Draw a square body

Add a triangle head

Draw two circles for eyes

Add a rectangle for the mouth and add some lines

Draw a rectangle on the head

Add a circle to the rectangle

Hold up your robot!

Does your robot look like this?

Algorithm An algorithm has to be written so that it can be followed exactly.

Your turn! Draw a robot using triangles, rectangles, squares and circles - keep it secret! Write an algorithm for your friend to follow to draw the same robot Does your friend's robot look like yours?

My robot algorithm by........................... Algorithm followed by...........................

Improve your algorithm Now improve your algorithm and let another friend follow it Does the robot look more like yours?
