GRADES:
3-5 Some elements
can be applied to lower levels by focusing on the measuring aspects of the
outline versus the math.
Essential Academic Learning Requirements:
Communication:
3.The student uses communication strategies and skills
to work effectively with others.
3.1 use language to interact effectively and responsibly with
others
3.2 work cooperatively as a member of a group
Mathematics: 1. The student understands and applies concepts and procedures of
mathematics
1.2 understand and apply concepts and procedures for
measurement
1. 3 understand and apply concepts and procedures for
geometric sense
5. The student understands how mathematical ideas
connect within mathematics, to other subject areas, and to real-life
situations
5.3 relate mathematical concepts and procedures to real-life
situations
 | angles:
the figure formed by two lines coming together at a common point |
| circumference:
distance or measurement around a round object |
| clinometer:
device to measure angles |
| diameter:
distance straight across a round object (taken at it’s widest point) |
| degrees:
a unit of measurement for angles (1/360 of a circle) |
| graph
paper: paper
with measured line grids marked on it |
| parallel:
lines or surfaces equal distance apart |
| protractor:
a part circular instrument for measuring & marking angles |
| tree
crown:
distance a tree’s branches spread away from its trunk |
| champion
tree: biggest
tree of its kind; biggest is determined from the tree’s height,
circumference and average crown spread |
| Pi
(π):
a mathematical number (about 3.14) representing the ratio of the
circumference of a circle to the diameter of the circle |
Teaching
Procedure:
-
Determine the Diameter and Circumference of a round object such as a tree trunk or round waste paper basket:
-
Determine the average crown spread of a tree:
-
Determine height of a tall object such as a tree, house or telephone pole
-
Learn what a “Champion Tree” is and how they are determined
