Organization: National Council of Teachers of Mathematics
Grade Band: Grades 3 - 5
Standard Goal: Algebra

model problem situations with objects and use representations such as graphs, tables, and equations to draw conclusions

Chaos	Lesson: Students learn about the concepts and applications of chaos.
Misleading Graphs	Lesson: This lesson will challenge students to think creatively by having them design and build water balloon catchers from random scrap materials, while requiring them to take into consideration a multitude of variables. Students will then construct at least two bar graphs to be used in a commercial advocating the purchase of their group's catcher.
A Better Fire!!	Activity: Students run a simulation of how a fire will spread through a stand of trees, learning about probability and chaos. Parameters: Forest density, wind direction, size of forest.
Adjustable Spinner	Activity: Create a game spinner with variable sized sectors to look at experimental and theoretical probabilities. Parameters: Sizes of sectors, number of sectors, number of trials.
Directable Fire!!	Activity: Run a simulation of how a fire will spread through a stand of trees, learning about probability and chaos. Parameters: Probability that a tree will set fire to each of its eight neighbors.
Fire!!	Activity: Run a simulation of how a fire will spread through a stand of trees, learning about probability and chaos. Parameters: Probability that a tree catches fire if its neighbor is on fire. Probabilities are input as fractions or decimals.
