6-8
Using three dimensional figures they have constructed, students determine when two isometric drawings can represent the same shape and explain their reasoning. Students will also determine what possible shapes might have the same isometric drawing and explain their reasoning.
6-8
Students examine some isometric drawings that seem to be impossible and
investigate one way Escher used to create these "impossible" figures.
Pre-K-2
In this lesson, students are encouraged to discover all of the combinations for a given situation. Students apply problem-solving skills (including elimination and collection of organized data) to draw their conclusions. The use of higher-level thinking skills (synthesis, analysis, and evaluations) is the overall goal.
6-8
In this lesson, students use cubes to develop spatial thinking and review basic geometric principles through real-life applications. Students are given the opportunity to build and take apart structures based on cubes.
6-8
A self discovery approach in understand the process of plotting points on a coordinate plane, using a program for TI Graphing Calculator.
9-12
Following their introduction to the Caesar Cipher, students will now learn about the polyalphabetic Vigenere cipher. Text will be encoded and decoded using inverse operations.
3-5, 6-8
The Factor Game engages students in a friendly contest in which winning strategies involve distinguishing between numbers with many factors and numbers with few factors. Students are then guided through an analysis of game strategies and introduced to the definitions of prime and composite numbers.
9-12
Students use graphs, tables, number lines, verbal descriptions, and symbols to represent the domain of various functions.
9-12
This lesson prompts students to explore ways of arranging squares to represent equivalences involving square- and cube-roots. Students’ explanations and representations (with their various ways of finding these roots) form the basis for further work with radicals.
9-12
Students will use a geoboard, geoboard interactive, or Geometer’s Sketchpad
® to help them discover the pattern of Pick’s Theorem.
