Quadrilaterals

Think, question, brainstorm, and make your way through a newsletter full of puzzles and word problems. The resource includes 10 different newsletters, all with interesting problems, to give class members an out-of-the box...

Young mathematicians complete a family math challenge packet. They will complete a packet of mixed math activities. They work with graphs, comparing numerical data, tessellations, and probability.

Four is the perfect number—if you're talking about parallelograms. Scholars determine a possible fourth vertex of a parallelogram in the coordinate plane given the coordinates of three vertices. They read a conversation...

Scholars must determine the maximum area for a rectangular plot of land enclosed with 100 meters of rope. As the work they discover patterns and numerical approaches to solve the problem.

Sliding over a corner makes a rectangle. The resource demonstrates why the formula of the area of a parallelogram works. As part of a larger playlist on basic geometry, the video works examples dealing with parallelogram areas.

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.

[Free Registration/Login may be required to access all resource tools.] Students watch a video and attempt practice problems on how to determine missing angles within rectangles and squares.

Find the area of a rectangle, square, parallelogram, and rhombus by multiplying the base by the height. A well-designed lesson has scholars first view a video showing examples of finding the area of a parallelogram before practicing...

Get introduced to the idea of square units and how to calculate the area of a parallelogram. The resource provides a visual lesson to measuring different types of this shape and how it relates to square units. 

Discover how triangles are congruent based on their sides, angles, and proportionality. Learners explore the ways to determine similarity at their own pace, and then they practice afterwards with an assessment.
