NUMB3RS - Season 3 - "Killer Chat" - The Perfect House
The FBI found three bodies in different unoccupied houses, all for sale. Because the victims are completely unrelated, Charlie decides that profiling the houses might reveal a distinct pattern to find out where the killer will strike next. By using a Multi-Attribute Compositional Model, the house...https://education.ti.com/en/activity/detail/numb3rs--season-3--killer-chat--the-perfect-house
Number and Operation Sense: Whole Numbers
Students attain a basic understanding of numbers and number operations, developing number sense, and gaining fluency in arithmetic computation. They also learn to use the calculator to explore the mathematical principles behind the standard multiplication algorithm for multidigit numbers.https://education.ti.com/en/activity/detail/number-and-operation-sense-whole-numbers
Bats Triangular
Students use manipulatives to construct a pyramid. The manipulative pyramid then becomes the basis students use to construct a pictorial representation of a pyramid. The TI-10 is used to show symbolic representation of students actions and also aids students in viewing the developing pattern.https://education.ti.com/en/activity/detail/bats-triangular
Amazing Appetites
Students learn to count and solve original word problems. They learn to add by combining sets and subtract when removing the set. They use manipulatives to reflect the reasoning used in problem solving.https://education.ti.com/en/activity/detail/amazing-appetites
Vectors
Describes how to use the TI-89 for coordinate system transformations, vector algebra, and vector component transformations. The functions rec2cyl(), cyl2rec(), rec2sph(), and sph2rec() are created in this chapter for vector component transformations and are used in Chapters 10 and 11.https://education.ti.com/en/activity/detail/vectors
Who's in the House
Students construct a model of a house, drawing pictures of the people and pets in the house.
