Lesson Plan 2: Overview

OVERVIEW

Grade Level- 3rd

Subject- Math 

Topic of Study- Area and Perimeter 

Time Allotment- 1 Hour 

COMMOM CORE STANDARDS

CCSS.MATH.CONTENT.3.MD.C.5.A
A square with side length 1 unit, called "a unit square," is said to have "one square unit" of area, and can be used to measure area.

CCSS.MATH.CONTENT.3.MD.C.6
Measure areas by counting unit squares (square cm, square m, square in, square ft, and improvised units).

CCSS.MATH.CONTENT.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.

OBJECTIVES
1. Students will be able to demonstrate how to find the area of different shapes by counting square units and multiplying. 
2. Students will be able to demonstrate how to find the perimeter of rectangles and squares by adding different lengths and widths together. 

REFLECTION 

Assessing Prior Knowledge:

Prior to this lesson the students will need to be familiar with basic math skills; specifically, adding and multiplying. Prior knowledge will be assessed when I have students recreate scenes from the story. If they are not able to then I know that I need to take a few steps back and refresh the students on adding. I will assess their knowledge on multiplication when I create my own shapes for them to assess. Once again, if they struggle I will quickly review how to multiply two numbers together. I will use this information in my planning process my adjusting my pace. If I find that many students are struggling I will slow down and spend more time reviewing. This lesson would become a few days long, as we would be doing a lot more review and moving forward slowly. 

Planning Instruction: 

This content should be taught at this level because it's knowledge they will be in the future. Students need to know how to find perimeter and area to continue and succeed in future math classes. This is also appropriate for 3rd grade because the story that goes with the lesson is age appropriate. The standards and objectives align perfectly because we are learning about the different aspects of area and perimeter. The students are also getting hands on experience working with the two. This lesson will be taught towards the middle of the year. Students will be taught how to add and multiply prior to this. This is also a complex way at looking at math for them so it would be unrealistic to throw it at them at the beginning of the year.
