The 'background' of this lesson -builds on the learner experience around: basic movement using the mouse -to drag code blocks. These are placed in the orange sections in the coding section. The trigger is setting off the competition -through an appropriate event (on click). 

In this lesson we work together -constructing a system of objects moving- based on the trigger. That is the clicking on the background -which starts the snail race. This lesson explores movement, through the snail race. There speed of these snails are measured in steps.  

The 'snail movement' across a race course (our background). Initial designated speeds are supplanted by the random number -which brings in the idea of automation i.e., in that the computer will assign a number. I can see how this lesson could fit into a mathematics lesson -with Grade 4-7 learners, graphing the outcome of various snail races. The importance of this is to see the germ of something more than it is plainly perceived to be.
