Our week commences tomorrow with Pi day, a celebration of the irrational number that plays such an important role in the geometry of circles. Rumor has it that there will be a special treat in class tomorrow (with chocolate chips)...
For the rest of the week, we will continue our exploration of fraction concepts. We'll begin by finishing up our practice modeling fractions on graph paper without using rectangular shapes. Remember, when you're dealing with fraction parts, the size of the fraction matters, but not the shape.
We'll then continue modeling fractions both concretely in class and virtually on the Internet. I've got a great class activity to do with pattern blocks, and a couple of nice websites to check out.
We'll also do some work on comparing the size of fractions, especially the crucial understanding that as the size of the unit fraction's denominator gets larger, the size of the fractional part of the whole gets smaller. By this logic, 1/2 is a larger piece than 1/3, 1/6 is a larger piece than 1/10, etc.
Homework will be posted here later in the week.
See you tomorrow...
Mr. Leitzell
