Measurement Moments

9/20/2014

 
     This week we began  a new math module.  We are working on activities designed to deepen students’ understanding of measurement and relate it to addition and subtraction in length.  In our first lesson, students placed centimeter cubes end-to-end along various objects.  The objective was to help students discover that they can’t have any gaps or overlaps between the cubes to get an accurate measurement.  
     In the second lesson, the students used one cube, made a mark, advanced the cube, and made another mark to determine the length.  This mark and advance technique gives students hands on experience covering the distance between 0 and 1 on the ruler.  A common error for students is to start at the number one instead of zero. By measuring this way they realize that each mark indicates the amount of space already covered.  Students created their own tagboard centimeter rulers using the mark and advance technique. Making the ruler helped  them  internalize the size of a centimeter and estimate length in centimeters.  
     We read another tall tale from the American Frontier called “Casey Jones.”  After the railways were built trains started moving people more quickly throughout the country.  Casey Jones was a steam train engineer who  prided himself on always being on time.  Casey became a hero when he tried to stop the train from crashing.  He lost his life, but saved the lives of everyone else on the train. As with “John Henry,”  it is believed Casey Jones is based on a real-life person.  The story grew into a tall tale through many years of retelling.   All the tall tales we have been reading  contain examples exaggeration and humor.  Also, tall tale characters have unbelievable childhoods and do amazing deeds as adults.
