D 4"bbbbbb Solving One Step Equations (Day 3) Initial Consideration Grade: 7-12 Length of lesson: 90 min Subject: Properties of Equality Age of Students: 12-18 Prerequisite skills: Numeric and Algebraic Expressions, Opposite Operations Lesson Plan Focus and Review (15 min): Review operator vocabulary and opposite operations (previous lesson). Give each student two pieces of construction paper. Have students to quickly draw a large plus (+) sign on the front of one piece of paper and a large minus () sign on the back. Do the same on the other piece of paper, for multiplication (x) and division ((). Call out operators and have students hold up the correct response. Statement of the Objective (1 min): 2.04 Use systems of equations and inequalities to model and solve problems using algebraic properties; justify results. Teacher Input (30 min): Once you feel your students have grasped the idea of what an equation is and is not, you will want to review the names of the properties that they will use in working with and solving equations. Do as much review of properties as your students need. Commutative Propertyo + ( = ( + o Symmetric Propertyo = ( then ( = o Addition Propertywhat you add to one side you must add to the otherSubtraction Propertywhat you subtract on one side you must subtract on the otherMultiplication Propertywhat you multiply one side by you must multiply the other side byDivision Propertywhat you divide one side by you must divide the other side by Have students create a study guide, using construction paper. Have students take a sheet of construction paper and fold it in half. After paper has been folded have them cut one side (left side) into six 1 in strips. Students should close the folds (left side) on the top of the right.       On the front of the strips students are to write the following six words: commutative property, symmetric property, addition property, subtraction property, multiplication property, and division property. Students should open each fold and write the definition, a visual image, and/or an example for each word, as the instructor presents the material to them. Guided Input (20 min): Once you feel your students are comfortable and understand the properties you may want to play the game Concentration using the overhead. Divide the students into groups of 3-4. A different student from each group should give you a match. Students will call out the row letter and column number. If it is a match leave the pair uncovered, otherwise, leave them covered. (Post-it notes make good covers for the overhead. You can see the answers but the students cannot.) Independent Practice (20 min): Students should individually complete the Properties of Equality worksheet. Review answers after completion. After the completion of the worksheet give a short pop quiz on concepts learned on day 1 & 2. Closure (5 min): The instructor should summarize the lesson by emphasizing the importance of the Properties and how they will play a large role in solving one step equations. Remind students about test Friday. Concluding Consideration Assessment: Students should complete worksheet and show understanding with 85% accuracy. Self-Assessment: Complete a self assessment on what went well, what didnt go well, and what students had most difficulty with; write down ideas on how improvements can be made for future lessons. Material/Supplies: construction paper, scissors, Properties of Equalities worksheet, overhead projector, Concentration transparency, post-it notes, pop quiz.
