Description of Lesson/Activity: Students were asked to list their Christmas gifts. As a class, we decided on categories such as "Toys", "Clothes", and "Pets" to sort and classify gifts. Students computed fractional and decimal parts for each category. After finding the number of degrees of a circle necessary to represent each fractional part, students used compasses, straightedges and protractors to construct a circle graph to display the categories and percent of total gifts represented by each.


Number Sense:
1.2 Add, subtract, multiply, and divide rational numbers (integers, fractions, and terminating decimals).
1.3 Convert fractions to decimals and percents and use these representations in estimations, computations, and applications.

Algebra and Functions:
1.5 Represent quantitative relationships graphically and interpret the meaning of a specific part of a graph in the situation represented by the graph.

Measurement and Geometry
3.1 Identify and construct basic elements of geometric figures (central angles, radii, dameters) by using a compass and a straightedge.

Mathematical Reasoning
2.5 Use a variety of methods, such as words, numbers, and graphs to explain mathematical reasoning.
