Benchmark Number: MA.4.G.3.3
Benchmark Description: Select and use appropriate units, both customary and metric, strategies, and measuring tools to estimate and solve real-world area problems.
Subject Area: Mathematics  
Grade Level: 4  
Body of Knowledge: Geometry  
Big Idea: BIG IDEA 3 - Develop an understanding of area and determine the area of two-dimensional shapes.  
Date Adopted or Revised: 09/07  
Date of Last Rating: 06/07  
Cognitive Complexity: Moderate  -  What does this mean?  
Status: State Board Approved  
Remarks/Examples: Students should recognize that the area of a piece of paper might be measured in square inches, the area of a room might be measured in square feet, and the area of a large piece of land might be measured in square miles. Alternately, these measurements might be in square centimeters, square meters, and square kilometers, respectively.

 

Example: Students find the area of a composite shape. An L-shaped region may be decomposed into rectangular regions.

 

Example: Find the area of the polygon in the picture. Explain or show how you found the area.

Good Benchmark Tie (2)

Resource Type(s)
» Parking at the Mall (Area)
Students estimate and determine the area for parking spaces at a mall.  They are also introduced to determining percents.  This is Lesson 1 of a two lesson sequence.
Lesson Plan
Worksheet
» Sidewalk Capers
Students will explore spatial relationships by determining the area of various shapes and creating tessellation patterns. They use a variety of manipulatives in this lesson to explore spatial relationships of squares and their transformations. ...read more

Reporting Category: Geometry and Measurement
Item Type(s):
This benchmark will be assessed using: MC , GR items.
At Grade 4, this benchmark will be assessed using MC and GR items.
Clarification: Students will find the area of a rectangle by multiplying the base by the height.

Students will solve problems involving the area of a rectangle or a composite shape composed of adjacent rectangles, such as L- or E-shaped figures.

Students will select appropriate units and/or tools to estimate and/or solve real-world area problems, (e.g., recognize that the area of a room is expressed as square feet, compared to an area of land expressed in square miles or kilometers).
Content Limits: Items may include figures with whole-number dimensions of 100 or fewer units.

Items will not include the formula for area of a rectangle.
Stimulus Attributes: Items may be on a grid, but this is not required.

Graphics should be used in most items.

Students may be required to use a ruler to measure the dimensions of a figure to determine its area.
Response Attributes: Responses may include incorrect units of measurement.
Prior Knowledge: Items may require the student to apply mathematical knowledge described in the Standards from lower grades. This benchmark requires prerequisite knowledge from MA.3.G.5.1.
