TEKS 4.5D: Perimeter and Area Problems
Solve Problems Related to Perimeter
About this lesson
Learning Target: I can solve problems related to the perimeter of rectangles using whole number side lengths.
Focuses On:
- Defining perimeter and the process needed to find it
- Finding the perimeter of rectangles given the length of two sides
- Solving word problems involving perimeter
Builds On:
3.7B:
Determine the perimeter of a polygon or a missing length when given perimeter and remaining side lengths in problems.
Next Level:
5.4H:
Represent and solve problems related to perimeter and/or area and related to volume.

This lesson is designed to support student understanding of perimeter and how to determine the perimeter of a rectangle when given 2 side lengths.
The two instructional blocks in this lesson are calculate perimeter and perimeter word problems.
The first instructional block introduces students to the important terms related to perimeter. Students are given support as they are asked to find the perimeter when given 2 side lengths on a labeled diagram.
The second instructional block progresses in difficulty as students must solve word problems involving perimeter.
Visual representations and partially completed equations are built into the lesson to support student understanding.

About this lesson
Learning Target: I can find the area of a rectangle by using the formula: area = length x width.
Focuses On:
- Defining and using terms related to area
- Find the area of a rectangle by first counting the number of rows in columns
- Using the area formula to determine area
- Solving word problems involving area
Builds On:
3.6C:
Determine the area of rectangles with whole number side lengths in problems using multiplication related to the number of rows times the number of unit squares in each row.
Next Level:
5.4H:
Represent and solve problems related to perimeter and/or area and related to volume.

This lesson is designed to support student understanding of area and how to determine the area of a rectangle.
The two instructional blocks in this lesson are calculate area and area word problems.
The first instructional block starts by introducing the important terms related to area. Students are given support as they determine the number of rows and columns in a rectangle filled with square units. The lesson progresses in difficulty as students determine area using a rectangular model with 2 given side lengths.
The second instructional block has students solving word problems related to area.
Pictorial representations of area models are built into the lesson to support student understanding.
