Question 2
Do "Reflect 4.4" (from the notes) and put your answers in bullet form. See the attached pdf.
Reflect 4.4
Consider the paired measurement tasks on area and perimeter in
figures 4.13 and 4.14.
What mathematical ideas do these tasks emphasize?
What ideas do students need to understand and apply to arrive at the
correct result for these tasks?
How would you predict that your students would perform on these
tasks?
On the grid below, draw a rectangin with an area of 12 square units.
(Assume that the the distance betwean neighboring horizontal dots and neighboring
vertical dots is one unit)

On the grid below, draw a rectangle with a porimater of 14 units. (Assume that the
distance between neighboring horizontal dots and neighboring vertical dots is
one unit)
