1/14/2008 Pre Algebra - Adding & Subtracting Unlike Fractions

Today we will continue our review work with fractions, adding & subtracting unlike fractions.  This will involve finding the least common denominator (least common multiple) before adding or subtracting.  Students will do some example problems in their notes, then submit their questions and work on the assignment.

Homework:

pages 234-235 #'s 12-19, 24-27, 36-39, 46-48

1/14/2008 Algebra 1 - Graphing Inequalities in the Coordinate Plane

Today students learned how to graph linear inequalities in 2 variables using the process below:
1) Plot the y-intercept
2) Move to the next point using the slope
3) Draw a dotted or solid line
4) Shade above or below the line

Students took notes on some example problems done on the board, then did a worksheet for practice. When we were finished going over it, they worked on the graded assignment due for Thursday. Graph paper can be printed out here.

Homework:
p. 363 #'s 16-22 even, 43-48, 61-63 & worksheet

1/14/2008 Applied Geometry - Similar Triangles

Today we continued with simialar triangles. We talked about the 3 Similarity Postulates, the Angle-Angle Similarity, Side-Side-Side Similarity, & Side-Angle-Side Similarity Postulates.  Students took notes giving the 3 postulates and how to use them.  Students also wrote down the answers to their questions they asked last time and came up with 3 questions for the new lesson.
