Paper Pool : Analyzing Numeric and Geometric Patterns
ORC# 394
Resource Information
Resource Type: Lessons
Discipline: Mathematics
Professional Commentary: Paper Pool is played with an imaginary ball being hit from the lower left-hand corner of a rectangular grid (pool table) at a 45&amp;#176 angle. A ball hit at this angle will bounce off the side rails of the table at a 45&amp;#176 angle and will traverse the diagonals of the squares in the grid....

Fit By Design or Design To Fit: Mechanical Drafter Designer
ORC# 1282
Resource Information
Resource Type: Lessons
Discipline: Mathematics
Professional Commentary: Students use a carpenter's square and protractor to measure the sides and angles of several right triangles. To confirm their measurements, they then compute the size of selected sides and angles using (a) the Pythagorean Theorem and (b) trigonometric ratios....
