7th Grade Task: Plant Species

Standards & Objectives

Essential and guiding questions:

How does the use of a diagram help you with your problems?
Compare the different solution paths. Some of you gave me rates as the number of squares per hour and others gave me rates as the fraction of the field completed per hour. Are these equivalent? Why or why not?
Did your different rates result in different graphs in part (e)? Why or why not?

Activity/Task Variations

Blooms taxonomy level:

Understanding

Extension suggestions:

One of the key pieces of information students need to know is how many 1 foot by 1 foot squares are marked off. How many 1 foot by 1 foot squares are in Darien’s plot of land? How do you know? Can you draw a picture to show me how you know?
Several parts of the problem can be approached in different ways. Compare your work to someone else’s (who worked the problems in a different way). Explain your approaches to each other. Do you both get the same answers? Why or why not?
