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.

In this activity students will analyze data and select fictional
baseball players based on player statistics. They will apply concepts of
probability to choose the order of batters on their team. After creating a
spinner for each player to represent the statistics, they use the spinners to
play a simulated baseball game.
3-5
In this lesson, students explore the relationship
between perimeter and area. Students use pattern blocks to build polygons to
explore how the perimeter can be different for two or more polygons with the
same area.
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.
3-5
Students learn to calculate elapsed time by using a
timeline, and then complete three engaging and fun activities that plan a
circus performance, their class schedule, and their day.
3-5
Use this applet to determine the volume of a box by filling it with cubes, rows of cubes, or layers of cubes. Determine the surface area as well by using the box's net.
3-5
Using an area tool on the computer, students will begin to develop an understanding of area. Students will use 12" × 12" paper squares to measure the area of a door. They will determine whether area increases or decreases as the length or width of their door changes.
3-5
Engage students in a study of triangles and their
properties.
3-5
Use organization, preparation, and
presentation of foods as a way of applying various
mathematical concepts, with problem-solving techniques being central to
almost all the activities.
Pre-K-2, 3-5, 6-8
Focus
on patterns and relations
that can be developed from the exploration of balance, mass, length of
the mass arm, and the position of the fulcrum.
