Standards for Mathematical Practice

1.  Make sense of problems and persevere in solving them.

Barbie Bungee

The consideration of cord length is very important in a bungee jump—too short, and the jumper doesn’t get much of a thrill; too long, and ouch! In this lesson, students model a bungee jump using a Barbie^® doll and rubber bands. The distance to which the doll will fall is directly proportional to the number of rubber bands, so this context is used to examine linear functions.

2.  Reason Abstractly and Quantitatively

"The ability to contextualize and decontextualize."

Mathematically proficient students make sense of quantities and their relationships in problem situations. They bring two complementary abilities to bear on problems involving quantitative relationships: the ability to decontextualize—to abstract a given situation and represent it symbolically and manipulate the representing symbols as if they have a life of their own, without necessarily attending to their referents—and the ability to contextualize, to pause as needed during the manipulation process in order to probe into the referents for the symbols involved.

 Model Course Pathways 

Four model course pathways were created, each of which is intended to significantly increase the coherence of high school mathematics courses:

• A more traditional approach, with two algebra courses and a geometry course and data included in each;
• An integrated approach, with three courses that each includes number, algebra, geometry, and data;
• A “compacted” version of each pathway that begins in Grade 7 and allows students to study Calculus or other college level courses in high school.
