This grades 7-12 activity allows students to look for patterns within the given data. After looking at the pattern, the student should be able to form generalizations for the problem. Furthermore, this activity sharpens the algebraic skills of the students. The problem sharpens visualization skills.

Utilizando el juego en linea Deep Sea Duel, los estudiantes participan en un juego de tarjetas contra Okta. El objetivo es elegir tarjetas de modo que algún subconjunto de tres tarjetas den una cantidad determinada. Los estudiantes jugaran variaciones del juego, intentando identificar una estrategia ganadora, y harán comparacion de este juego con otros juegos que ellos conocen.

This activity allows students to look for functions within a given set of data. After analyzing the data, students should be able to determine what type of function best represents the data.

Starting from the concrete notion of weights and balance and moving to symbolic expressions and representations of functions, this i-Math investigation has focused on some of the issues that arise along the way. In this part, this connection is extended to functions. More sophisticated tools allow for a greater diversity of investigations.

This grades 6-8 activity focuses on interpreting and creating graphs that are functions of time. The first two activity sheets focus on graphs of time vs speed. The third and fourth activity sheets look at how many times an event occurred in a specific amount of time. These activity sheets are appropriate for students who have not taken algebra yet. This lesson plan was adapted from an article by Marian Moody which appeared in the December 1990 issue of the
Mathematics Teacher. 3-5
In this lesson, students use pattern blocks to create
polygon "chains" and calculate the perimeter of the trains as they get
longer. The students will recognize and create patterns based on adding the
same shape repeatedly to the train. The students then write algebraic
expressions to describe the patterns.

Studying the behavior and motion of dinosaurs is obviously a
challenge since these creatures are extinct. If researchers wish to examine the
running velocity of a dinosaur, they must instead consider other evidence of
dinosaur motion and make an indirect estimate. In this lesson, students will
play the role of researchers who field test the Alexander Formula—a formula that uses paleontology data to estimate dinosaur running
velocities. Students will serve as human analogues, making measurements on
themselves, computing predicted running velocities using the Alexander Formula,
and calculating their actual running velocities. They will then evaluate the
accuracy of the formula by comparing estimated and actual running velocities
for the class.

If a tree could talk, we could ask it how old it is. Here is a mathematical way to estimate the age of your schoolyard trees. Students will measure circumference of trees in order to find diameter and calculate age of local trees using a growth rate table.
