Class Experience

This class covers fraction basics, up to and including these third grade common-core state standards:

Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b.

Recognize and generate simple equivalent fractions, e.g., 1/2 = 2/4, 4/6 = 2/3. Explain why the fractions are equivalent, e.g., by using a visual fraction model.
Several LEGOS or LEGO-Like bricks. I will be using 2x8, 2x6, 2x2, 1x3, 1x2 and 1x1 bricks. I suggest pulling out several of these basic bricks, and leaving the mini-figures, wheels, and other specialty pieces out of class time. Student models will be flexible, for example, they can use 2 bricks of two different colors but the same size to show 1/2. One learner might have a purple 2x8 stacked with a white 2x8, while another might show a yellow 1x1 stacked with a green 1x1. Both show equal halves! A notebook or scratch paper and something to write with will also be helpful.
Learners will not need to use any apps or websites beyond the standard Outschool tools.
Students will compete in the fraction challenge at the end of class for "points." 
40 minutes per week in class, and maybe some time outside of class.
