Friday, April 10: Quiz, and Introduction to Angles

Today we took a short quiz on Rational Numbers.  If you were not here today, make sure you take this quiz on Monday!

We started our unit on angles, and today we used protractors and practiced measuring angles.  See notes below:

We started by drawing the given angles using a protractor.

Then we measured angles and defined angle terms.

We had a quick homework assignment that most students finished in class.  This is due MONDAY for those students that did not complete it before we left for the weekend.

March 9: Triangle Investigation

I was gone today, so our guest teacher had an investigation for Pre-Algebra today.  Students were to cut out squares of varying sizes, and use the sides of the squares to create triangles and record the data on the sheets given.

There are many relationships with triangle side lengths and the types of triangles that are created- specifically acute, obtuse, and right triangles.

Tomorrow we will look at the relationships we noticed and see what conjectures we can make!

See you tomorrow!
