What is the area? Because there is only one problem here with a detailed explanation below, consider projecting this as an all-class warm up. Learners examine a rectangle split into 12 squares. They know that each unit is three centimeters square and must determine the area of the entire rectangle. The explanation describes the area formula and uses square units in the answer.
While the lesson focuses on right triangles, this activity offers a great way to practice the area of all triangles through an interactive webpage. The activity begins with the class taking a square paper and cutting in in half; can they relate the area of the square to the right triangles? Then they use the webpage, which provides different triangles on a coordinate grid to calculate the the area. The lesson discusses right triangles, while medium and hard levels of the activity have non-right triangle examples. Learners should be able to find the area of a triangle when height or base is not obvious using the distance formula or box method if using the hard level examples. 
This is a good model for learners to visualize triangles of the same base and height. They can can begin to comprehend that these triangles will have the same area no matter how the triangle is drawn. It is part of a series of resources which makes a good transition question or mini-assessment.
In this algebra worksheet, students discover properties of squares while making squares with a Geoboard. There are two charts to complete and 15 questions.
In this geometry practice worksheet, students find the perimeter and area of 5 rectangles and list the answers in a chart on the page. They use grid paper to draw a square and a rectangle with the given unit measures. They complete 2 test prep questions.
Geometers find the perimeter and area of rectangles. They discuss the definitions and characteristics of rectangles and squares. In groups, they use yarn to discover the perimeter of squares and rectangles. They count cubes to explore the formula for the area of a rectangle.
Tenth graders explore the area of a square in a problem solving context.  In this geometry lesson, studetns are provided with a model , which if complete would form a square.  Students use Cabri Jr. to explore the area of the missing part of the square. 
In this online math worksheet, learners determine the length and width of given rectangles given their area. This excellent resource allows the students to check their answers, and to get "hints" should they run into difficulties. A terrific teaching tool!
If each square has sides measuring two centimeters, what is the area of this shape? Learners find area in five shapes segmented into squares with given sides. Encourage them to use square units in their answers. Next, they do the opposite: given a square and its area, they are asked to determine the measurements of each small square unit within it. Learners work only with whole numbers here, and there are 10 problems. Consider doing this as an all-class warm up or in small groups as it is three pages total.
In this area practice worksheet, students examine 6 figures and use their problem solving skills and the information provided to calculate the area of the squares and rectangles.
For this perimeter and area worksheet, 7th graders use the reference book information to help them find perimeter and area for the first two word problems. Students complete the last three word problems using the reference page measurements as well.
In this perimeter and area worksheet, 7th graders use the floor plan and elevation for the bedroom diagram to help them solve the word problems. Students write the missing information if there is not enough given to complete the problem.
Eighth graders explore the Pythagorean Theorem. They draw and construct non-congruent squares to determine their area. They construct triangles and determine the area and compare the sizes of both the squares and triangles. They record the relationship between the areas of the squares and construct two differnt right-angled triangles.
Students investigate quadratic equations and areas. In this algebra lesson, students convert word problems into algebraic equations to explore functions. They graph their equations and interpret the data to see if it represents a function.
Students examine the amount of usable space that exists in their classroom using square meters and square centimeters. They apply the information to predict the ideal size of a classroom.
Pupils explore the concept of measurement.  In this measurement lesson, students collect data about themselves such as height, finger length, neck circumference, foot length, and other body measurements.  Pupils cut squares of certain length out of paper and then they find the perimeter and area. 
In this area worksheet, learners count the square centimeters to determine the area for each figure. Students complete six problems.
Here is an activity that focuses on the actual construction of the square inscribed in a circle. The lesson allows for the use of dot paper or graph paper with straight edges and protractors, or dynamic geometry software programs. After construction, learners verify that the figure is a square. An additional small group activity has them approximate the percentage area of the square within the circle. 
Four triangles are depicted for learners to construct on a geoboard. They compute and compare the areas, and so meet one of the sixth grade Common Core standards for geometry. Note that the set of triangles does not include a right triangle, so to completely fulfill requirements, more resources are needed. This would make a compact pop quiz for your class.
Given measurement information on individual squares within a larger shape, scholars determine the total area of that square or rectangle. For one of these three problems they draw the shape knowing its total area and the measurements of each square within it. Consider projecting this as an all-class warm up because of the large text and few problems.
