Seventh graders use toothpicks to investigate a series of designs and identify patterns. Data is organized and analyzed using tables and graphs, and students make generalizations using algebraic expressions.

Students identify numbers in nature. In this algebra activity, students solve problems using Fibonacci sequence as it is expressed in nature. They research the Fibonacci's pattern as it relates to numbers.

Seventh graders play "What's my Rule" beginning with simple equations and working towards harder problems as student's gain confidence. They evaluate the equations by graphing them. Students identify the slope and y intercepts of the...

Students solve exponential problems using exponential properties. For this algebra lesson, students discuss the meaning of exponents, and bases raised to different powers. They explore exponential functions using a computer.

Fourth graders use colored beads in two problems and explore the use of proportional reasoning as a problem solving method. Working Students, in groups, explain their reasoning strategies orally, and through drawings.

Students are introduced to the function and design of the following Lego pieces: beams, bricks, plates, axles, tires, hubs and bushings. They then work with a partner to build something using only these pieces.
