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.

This tool allows you to manipulate various geometric solids and investigate their properties.
3-5, 6-8
Use this applet to create patterns to cover the screen using regular polygons.
3-5, 6-8
This applet allows you to examine various two-dimensional figures to determine which ones can be folded into a cube.
6-8
Use this tool to determine how the length of the base and the height of a
triangle, parallelogram, or trapezoid can be used to determine its area.
Pre-K-2, 3-5, 6-8
This tool allows you to create any geometric shape
imaginable. Squares, triangles, rhombi, trapezoids and hexagons can be created,
colored, enlarged, shrunk, rotated, reflected, sliced, and glued together.
6-8, 9-12
In this lesson, students will explore reflections,
translations and rotations. Students participate in a modeling activity where
they will learn the rules for translations and reflections. Then students
will practice using these transformations, as well as explore the rules for
rotations, in the game
Flip-n-Slide on Calculation Nation®.
3-5, 6-8
Students discover the
relationships between area and perimeter as they prep for playing Square Off, a
wonderful Calculation Nation
®
game. This lesson helps students understand the math of area and perimeter, which
will help to maximize their scores when playing the game. Creating human-sized
rectangles and working with geoboards provide concrete experiences before
moving on to pictorial and abstract work with area and perimeter of rectangles.
6-8
The
shortest distance between two points is a line. But what is the shortest time
to travel between two points on different terrains? In this lesson, students
will predict, estimate and then calculate the path that results in the fastest
time to travel between two points when different terrains affect the fastest
path. This lesson is designed as an introduction to the Calculation Nation
® game
DiRT Dash and prepares students to apply mathematics to improve their
performance in the game.
