Name:  Dan Fram, George Economides, Elizabeth Walton, Michael Gallagher

Subject:  Pre-Algebra

Date: 6/14/07 – Third Period (9:50-10:40)

Approximate Time:  50 Minutes

Objective:     

    TSW graph solutions for inequalities on a number line (2. d) TSW solve combining like terms inequalities in one variable. (2. c) TSW check solutions to combining like terms inequalities in one variable.(2. c.)

Materials:  whiteboard & markers, life-size arrows, dots, circles, and numbers, example project.

Warm-up:  Bell work will be on the overhead as the students enter, including 5 problems - review problems of solving and graphing inequalities. (8 minutes)

Designate students to display the problems on the board, and intervene when necessary to make corrections.  Ensure that all students have the correct answers and allow questions for previous material.

Set:  Fruit - the teacher will assign minimum prices to the fruit in order to result in a profit, and have the students determine how many pieces of fruit must be sold.  Yesterday we solved and graphed one and two step inequalities, but now we're ready to solve, graph and check inequalities that require us to combine like terms.  (6 minutes)

Procedures: 

•    After warm-up, teacher will guage which types of inequalities need additional practice.  Teacher will give notes and examples for combining like terms inequalities.

•    Students will complete practice problems from the textbook to practice.

Closure:  Cold call or ask entire class questions regarding the difference between equations and inequalities, what direction the arrow points for less than, greater than, how to solve, when to use circle/dot, etc to review.  Refer back to car example from set.  Tomorrow we will continue to solve and graph inequalities and since we’re getting much better at the simpler problems, tomorrow’s problems will be more complicated and involve more steps..  (4 minutes)

Assessment: 

Informal:  Teacher will observe students as they work (M) to ensure that they are correctly solving inequalities (C) and note students who need additional assistance in class log book (during club time or independent practice) (D). 

Formal:  Students will complete homework assignment (M) of changing equations to inequalities (C) and will be checked if selected for binder check on quiz day based on rubric and recorded in grade book (D) 

Students will take a quiz (M) on solving inequalities (C); grades for this quiz will be recorded in the grade book (D).

Students will create a project over the three week period (M) to demonstrate ability to solve equations and inequalities (C) and grades for the projects based on a rubric will be recorded in the grade book (D).
