> "If in a triangle the square on one of the sides equals the sum of the squares on the remaining two sides of the triangle, then the angle contained by the remaining two sides of the triangle is right." **8th grade:** **What does this statement mean?** [from Euclid's //Elements// (Book I, Proposition 48)]

 * Use Cuisenaire rods to show lengths we need to have a triangle in the first place. What observations can we share about triangles?
 * Backyard Improvements: Here is the problem. We need to fence our backyard. This yellow triangle represents our backyard. We know the length along the house (side AC) and we know the length opposite the right angle in our backyard. Can we figure out how long the fence needs to be on the third side of our yard? Can we figure how much fencing we need? Can we figure the area of our backyard too, in case we want to buy grass seed?

Another way to say it found in wikipedia: For any three positive numbers //a//, //b//, and //c// such that //a//2 + //b//2 = //c//2, there exists a triangle with sides //a//, //b// and //c//, and every such triangle has a right angle between the sides of lengths //a// and //b//.


 * Create a frequency table for rolling a six-sided number cube. Record each roll on your table. Roll your six-sided number cube 20 times.
 * Dalton rolled a six-sided number cube 20 times. Make a frequency table for his experiment. He rolled as follows: 6,1,2,6,3,6,6,5,1,1,6,6,6,2,5,3,3,5,6,6. Then answer this question. **What statement is true about Dalton's 21st roll? He is more likely to roll a 6 because most of his rolls have been sixes. He is more likely to roll a 4 because he has yet to roll a 4. He has an equal chance of rolling any number from 1 to 6 because each roll is independent. He will most likely roll a 1,2, or 3 because he's rolled a lot of high numbers so far.**
