The Area of Rectangles - Guided Lesson
2nd - 3rd CCSS: Adaptable
Geometry novices will enjoy this approach to finding area, as they aren't required to include units or a formula. The main objective here is to segment a rectangle into columns and rows to create squares, which then are used to find the...
Connecting Algebra and Geometry Through Coordinates
9th - 10th CCSS: Designed
This unit on connecting algebra and geometry covers a number of topics including worksheets on the distance formula, finding the perimeter and area of polynomials, the slope formula, parallel and perpendicular lines, parallelograms,...
Area and Perimeter of Rectangles: Lesson
3 mins 4th - 9th CCSS: Adaptable
Around and in—take a different look at rectangles. A portion of a basic geometry playlist discusses the area and perimeters of rectangles. Using the formulas, the presentation works perimeter and area examples with rectangles and squares.
Awesome Area - Geometry and Measurement
2nd - 4th CCSS: Adaptable
Break out those math manipulatives, it's time to teach about area! Capturing the engagement of young mathematicians, this three-lesson series supports children with learning how to measure the area of squares, rectangles, and other...
How Do You Find the Length of a Rectangle if You Know its Width and Area?
4 mins 6th - 12th
Learn how to use the formula for area to solve a problem about a rectangle. The demonstrator shows how to plug in the known values of a rectangle, and then how to use the formula for area to solve for the variable in question.
Kindergarten: Geometry (K.G.2) Formative Assessment Task
K CCSS: Designed
Can your kindergarteners correctly identify and name shapes regardless of their orientation or overall size? Use the templates provided with this geometry formative task or use pattern blocks and solid figures for the assessment....
Side Length, Perimeter, and Area of a Rectangle
9th - 12th CCSS: Designed
Learners calculate area, perimeter and length of rectangles. In this geometry lesson, students create different formulas for the problem they are being asked to solve. They use the navigator to move the shape around and make observations.
Find Perimeter and Area by Finding the Length of Sides by Comparing Coordinates
5 mins 5th - 7th CCSS: Designed
Using coordinates to draw a rectangle, help learners understand the relationship between the given order pairs used as the vertices and the length of its joining sides. This is the second video in a series of four using geometry to solve...
Derivative Formulas Through Geometry | Essence of Calculus, Chapter 3
19 mins 11th - Higher Ed
Geometry to the rescue. By watching a video, scholars see how geometric concepts help explain derivative formulas: areas of rectangles and volumes of rectangular prisms for the Power Rule and similarity and trig ratios for the Sine Rule.
