Stacking cheerios

Groups had a skewer and plastecine to stick it to the table.  Each member then had time trials of 5,10,15,20 seconds to place cheerios on the skewer with their non dominant hand. 
  

The results were shown on a graph as well as in tables of values.  At the end of the class, the fastest and slowest members of each group raced.  The group determined the head start (number of cheerios) to give the slower player so that they would have a tie at 20 seconds.

Competition got quite intense!

 We have a better sense about what the “initial value” or y intercept means in a linear relation.
