Eighth graders solve problems using proportions with scaled drawings. They work with maps and blue-prints discussing scales and plans and examine different polygons and figure out the scale factors or proportions they have been changed by.

In this dilations and similarity learning exercise, pupils solve 10 different problems that include various dilations. First, they determine the scale factor of dilations found in the illustrated graphs. Then, everyone determines the...

Are congruent shapes compatible? Congruent shapes are identical to one another, and throughout the assessment, young mathematicians identify given shapes as congruent.

Students calculate the surface area and volume of shapes. In this geometry instructional activity, students create different scales and calculate the volume and area for each shape. They compare and contrast between the different scales...

Five questions make up an interactive designed to boosts knowledge of area and volume of solid figures. Question types include multiple-choice, true or false, and fill-in-the-blank. A scale model changes measurement to provide a visual...

Here is a lesson that has learners take a look at corresponding parts of similar triangles, ratios of similarity, reductions and enlargements. They'll manipulate the scale factor (r) to observe the changes in similar triangles and then...

Eighth graders understand that proportional enlargement of shapes doesn't change the angles of those shapes. In this similarity lesson plan, 8th graders complete exercises to create enlargements of shapes and understand similar shapes.

Students use ratio and proportions to solve problems. In this geometry lesson, students apply ratio and proportions to real life scenarios.

Seventh graders investigate the area and volume of 2D and 3D figures. In this geometry lesson, 7th graders create a storyboard explaining their knowledge of 2D and 3D shapes. They analyze their data and interpret their...

Twelve chapters cover a multitude of math concepts found in the Common Core standards for sixth grade. Each title provides a brief explanation of what you will find inside the chapter—concepts from which you can click on and learn more...

Students explore similar figures. In this surface area and volume instructional activity, students identify the relationship between the surface area and volume of similar figures.

Students predict the shape of a geometric figure in 3D. In this geometry activity, students construct 3D shapes to perfect their knowledge of measuring and predicting. This assignment is also available as an online interactive...

Students build a working definition of a regular fractal, they measure the concepts of dimensions and scale, they explore the concept of a logarithm and they attempt to solve simple exponential equations for the exponent both by trial...

Students differentiate between similar and congruent triangles. In this geometry lesson, students identify the angles of triangles using the similarity theorem. They apply concepts of triangles to the real world.

Students, through lecture and guided practice, discover the properties of similar triangles. They use given measurements of one triangle to find a missing measurement of a similar triangle. They apply this knowledge in real-life...

Having a good working knowledge of math vocabulary is so important for learners as they progress through different levels of mathematical learning. Here is 125 pages worth of wonderfully constructed vocabulary and concept review cards....

Compose and decompose sets of 13 and 14 and compare sets of each with your little learners. They use objects to construct sets of 13 and 14, record their answers, and compare sets in several different ways.

Students explore the concept of perimeter. In this perimeter lesson, students discuss how to find perimeter of various shapes. Students use the Perimeter Explorer applet to find the perimeter of various shapes.

Learners investigate an accident and relate it to math. In this trigonometry lesson, students measure the accident scene, the friction produced, and the speed from the skid marks. They create a poster of their findings.

Students explore universe, and examine how big it really is and how scientists measure the distances or sizes of things by estimating sizes of different objects and reading and writing numbers in scientific notations.
