Monday, January 27, 2014  Finding the Area of Parallelograms and Triangles Using Formulas
Bell Work  Countdown Week 8 using the Holt textbook p. GA11
Classwork  Graded classwork turned in last Friday was returned. These were the decomposed, recomposed figures from Activity 13. Students were graded on accuracy and completed work. Please see last Friday for an example of the work. Using their work, students completed more guided practice on finding the area of parallelograms and triangles using problems from the PowerPoints attached below. Afterwards, students were given time to work on homework. Remember that the base and height must be perpendicular to each other, which means they will intersect and make a right angle at this intersection.

Homework  Complete "What is the Best Way to Catch a Squirrel?" Show organized work for all problems. Provide the area formula needed (either A = bh for parallelograms or A = 1/2 bh for triangles). Then substitute the values of the base and height. Remember that the base and height are perpendicular to each other making a right angle at their intersection. Finish the equation by solving for the area.

Tuesday  January 28, 2014  Finding the Area of Trapezoids
Due to inclement weather, only 3rd and 4th period experienced today's lesson.
Bell Work  Countdown Week 9 from the Holt textbook p.GA12 (before the table of contents).
Classwork  Students received guided practice on how to find the area of trapezoids by decomposing the trapezoid into triangles or a combination of triangles and parallelograms. After several examples, students were shown how to use the formula for trapezoids A = 1/2 (base 1 + base 2) h. They saw how using the formula is derived using the distributive property and common factors. They are not expected to master this formula, but they should master the understanding that a trapezoid's area can be found through the sum of the areas of the two triangles that create the trapezoid.
3rd period completed problems 1  5, then had to choose one problem from questions 6  8 to do on their own. Work was turned in at the end of class.
4th period completed problems 14, then had to choose one problem from questions 5  8 to do on their own. Work was turned in at the end of class.

Friday  January 31, 2014  Find the Area of Trapezoids
Bell Work  Countdown Week 10 from Holt textbook p.GA13 (before the table of contents).
3rd and 4th Period
Classwork  Graded work from guided practice on Tuesday was returned. Work was graded on accuracy and completion. Labels, formulas, and organized work should be present for all problems. An example has been attached below. Students were also graded on a level of 1  5 for their understanding on the problem they chose to independently complete. This score will not be put in the gradebook, but was used to assess progress.
Students shared solutions for the remaining problems #48. Then worked in group to complete "Area of Trapezoids." They will finish this assignment on Monday, February 3, 2014.
4th period turned in their work for me to assess progress.

5th and 6th Period

5th Period  3rd period completed problems 1  4, then had to choose one problem from questions 5  8 to do on their own. Work was turned in at the end of class for grading. 4th period completed problems 15, then had to choose one problem from questions 6  8 to do on their own. Work was turned in at the end of class for grading.

No Homework! Enjoy the weekend!
