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