LESSON PLAN TEMPLATE – 2015GENERAL INFORMATIONLesson Title & Subject(s): “Hot or Cold?” (A Lesson on Adding and Subtracting Degrees on a Thermometer/ Number Line Diagram)Topic or Unit of Study: Unit 3: Understanding Measurement, Length, and TimeGrade/Level: Second GradeInstructional Setting:Second grade classroom; Class of 20 students, seated in 5 groups of 4, pre-determined by ability grouping outlined in “differentiation” section of lesson plan; students seated by grouping just previous to beginning of lesson; Groups arranged in “U” shape, providing teacher space in center of room and “front of the room” white board focal point for direct instruction. STANDARDS AND OBJECTIVESYour State Core Curriculum/Student Achievement Standard(s):MGSE2.MD.6 Represent whole numbers as lengths from 0 on a number line diagram with equally spaced pointscorresponding to the numbers 0, 1, 2... and represent whole-number sums and differences within 100 on a number line diagram.Lesson Objective(s):Students will demonstrate their understanding of using a number line diagram (thermometer) to add and subtract, given 4 prompts and a thermometer number line diagram worksheet, with 75% accuracy. MATERIALSInstructional Materials:Teacher white board/dry erase markers; student white board/dry erase markers; Student thermometer number line diagram sheets(laminated, so they can be used with dry erase markers); Teacher thermometer number line diagram, projected onto white board by document reader.INSTRUCTIONAL PLANSequence of Instructional Procedures/Activities/Events (provide description and indicate approximate time for each):1.Student Prerequisite Skills/Connections to Previous Learning:Students must have previous understanding of basic 2 digit adding and subtracting, previous familiarity with number lines, previous familiarity with using number lines to complete the operations and addition and subtraction (This lesson would be delivered on the 3rdday of a week-long unit, after 2 previous days of practicing carrying out the operations of addition and subtraction, using a number line.)
2.Presentation Procedures for New Information and/orModeling: 20 minsPresentation Procedures for New Information/ Modeling:The purpose of this lesson is to offer additional practice subtracting and adding using a number line, while introducing the connection to the grade appropriate skill of measuring temperature on a thermometer. As an introduction to the lesson, the teacher will draw a vertical number line on the board. Calling on a student from a raise of hands, the teacher will ask what looks different about this number line compared to the number line the class has been using earlier in the week. Extending upon student response that this number line “goes up and down” while other number lines are “side to side” (or the equivalent response), the teacher asks the whole group if the number line looks the same, otherwise. Stating that “We better test it out, to make sure it is the
