Transcript of Math Lesson Plan - Geometry
Brad ColemanSpring 2014Math – GeometryPerimeter Day 1
Learning Goal My learning goal is to present a math lesson in a timely manner that is
interesting and understandable to the students My learning goal is to maintain acceptable classroom management
throughout the lesson, including an activity that takes us out of the classroom
Rationale I am teaching this lesson to introduce the topic of perimeter This lesson is important because the unit continues with more perimeter and
area, the latter of which can be difficult to understand without understanding perimeter
This lesson fits into the big picture as part of the geometry unit
Source The guidelines for this lesson come from Envision Math. I have collaborated
with Liz for ideas and used my own ideas to make it my own
Objective Students will use shapes to find basic perimeter and begin to understand the
formula of adding the sides Students will notice they can find missing sides from given information
Standards 3.MD.D.8 – Solve real world and mathematical problems involving
perimeters of polygons, including finding the perimeter given the side lengths, finding an unknown side length, and exhibiting rectangles with the same perimeter and different areas or with the same area and different perimeters
Materials QOD on whiteboard “Finding Perimeter” in class worksheet HL 94 homework Perimeter activity
o Recording sheeto Masking tape
ProcedureIntroduction
QOD: I need to put a fence around my yard. How can I find out how much fence I need?
o Discuss answers – measure around the yard Introduce perimeter
o The distance around a figure
Lesson Development Draw example figure on white board
o Label each side in inches Show the perimeter (sides)
o How can we find the perimeter? Add side lengths Mark off sides as counted Remember unit
Pass out in class worksheeto Complete as a class for understanding of perimeter concepts
Perimeter activityo Students will work in partnerso 5 stations set up in the hall
Tape forming shapes 1 tile = 1 ft
o Find the perimeter at each station and record it on handouto Review hallway behavior
Teacher observes and helps groups in hallway during activity When groups are finished, they may work on “Understanding Perimeter”
Differentiation Teacher will help struggling groups during activity
o It is okay for struggling groups to go at needed pace
Conclusion What are some ways we can use perimeter in real life? Envision video time permitting
