Jump into equivalent fractions using these fun scenarios for mathematicians to solve. First, they use geoboards to find different ways to divide a rectangle in half. Then, an alien from the planet Fractional is after one half of their...

Six rectangles representing gardens are lined up across the top of this handout. Learners help Mr. Aldo, Lori, Monica, Kip, and Mr. Torez answer questions about their gardens by computing area, perimeter, or cost to cover a garden with...

Young learners read 2 examples of how to write fractions to show how much of a rectangle is shaded. Then students look at  9 diagrams of rectangles that have shaded areas. They write the fractional equivalent. Then they shade 3...

Young scholars explore tessellations. For this shapes and geometry lesson, students describe the attributes of many of the shapes displayed on an Elmo. Young scholars create examples of tessellations using pattern blocks.

Infuse your CAHSEE Prep sessions with this video, which takes students through basic geometry, algebra, and graphing problems. Students will find the annotation and narration engaging, informative, and most importantly, helpful for...

Use rectangles to find distances. Given a rectangle and three associated triangles, pupils determine the area of the triangles. Scholars know the three triangles have equal areas along with the perimeter of the rectangle and two other...

Take a coordinated look at rectangles. The task asks pupils to plot the length and width of created triangles in the coordinate plane. Using their plots, scholars respond to questions about rectangles and their associated points on the...

All the 2-D and 3-D measurement work you need is in one location. Divided into three sections, the geometry lesson plans consist of visualization of three dimensions, classifying geometric figures, and finding surface area and volume....

Tip the scale in your favor when learning about scale factors. After viewing a video clip of a learner trying to determine the scale factor of the areas of two rectangles, scholars consider how changing the dimensions of a rectangle...

When does the Pythagorean Theorem come in handy? An intriguing video uses the Pythagorean Theorem to solve problems other than simply finding the length of a side of a right triangle. Pupils find the diagonal of a rectangle and the...

Model finding the area of a rectangle using a helpful video lesson. Young scholars watch as the instructor shows how to find the area of a rectangle. Additionally, the instructor shows how to calculate the length or width when given the...

Just how big of a TV do you need?! The task at hand asks individuals to compare the area of 80-inch and 55-inch TVs. The length of the TV is given and learners must use the Pythagorean Theorem to determine the width to calculate the areas.

They've all got four sides, but some have more interesting properties. Scholars learn the names of quadrilaterals. They also explore some properties of these quadrilaterals, including congruent angles, congruent and parallel sides, and...

Don't let your classes get stuck on area calculations—grab their attention with an inquiry-based lesson! Scholars must develop a plan to determine how may sticky notes it takes to cover the surface of a door. They decide on the...

Here's hoping that we can all fit into the pool. Given pictures and dimensions of a pool in tile lengths, scholars decide how many people can fit into the pool. This requires consideration of area, as well as the application of some...

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.

Properly organize parallelograms. Given special parallelograms, the narrator of a short video explains the properties of each. The section of a playlist on geometry uses the properties to classify the special parallelograms.

You can't often tell pupils that units don't matter ... but in this case, you'd be right! Math scholars discover the magic of the constant dimensions of a rectangle through a creative lesson. Partners perform measurements of rectangles...

Coordinate the classification of quadrilaterals. Given the definitions of special quadrilaterals, a portion of a geometry playlist highlights ways to classify a quadrilateral. The video takes information from figures on a coordinate...

Begin from the inside and work outward. Pupils construct quadrilaterals based upon the descriptions of the diagonals. Pairs then work through several configurations of diagonals and determine the types of quadrilaterals they can form....

Make the right connections between the equations of perpendicular lines. Pupils find the equation of a line perpendicular to another line in the context of finding the equation of a side of a geometric figure. Learners write their...

Make connections between geometry and algebra concepts. Using a point on a side of a geometric figure and the equation of the line that contains the parallel opposite side, learners find the unknown equation of the line. They write the...
