#### Essence of Linear Algebra

The 15 videos in the Essence of Linear Algebra collection teach students how to understand the numerical operations of matrices as well as the geometric intuitions underlying them. The first video in the series details the rationale...

Lesson Planet: Curated OER

#### LIDAR: Mapping with Lasers

We would be lost without maps! How are they made? Introduce junior topographers to LIDAR technology with a fascinating activity. Set up a mock city, then have learners operate a laser measure to determine the shape of the landscape using...

Lesson Planet: Curated OER

#### Linear Combinations, Span, and Basis Vectors | Essence of Linear Algebra, Chapter 2

What does it mean for two vectors to be linearly independent? The resource presents the basics of basis vectors and linear combinations. The third video in the 15-part series provides a definition of linear independence in terms of the...

Lesson Planet: Curated OER

#### Network Solids and Carbon

Allotropes of carbon are a girl's best friend. Here's a video thatÂ covers the various networks of solids and carbon, including the process for changing graphite network structures to diamond and then back to graphite. The video concludes...

Lesson Planet: Curated OER

#### 2D and 3D Shapes

What a great assessment to give young mathematicians in order to test their knowledge on two- and three-dimensional shapes. Learners name various shapes, identify the number of edges, faces, and vertices, match an unfolded version of a...

Lesson Planet: Curated OER

#### Photo Nets (3D)

The sky is the limit when printing custom 3-D shape templates from this site. Not only can you pick your shape and pattern, there is an option to upload an image for the different sides of the geometric shape. Let your learners have fun...

Lesson Planet: Curated OER

#### Describe 2-Dimensional Cross Sections of Right Rectangular Prisms

Help your learners visualize the resulting shape when a right rectangular prism is sliced with a two-dimensional plane in this first video in a series of two. Start by going over the key vocabulary shown at the beginning of the core...

Lesson Planet: Curated OER

#### Cylinder: Student Worksheet

Pairs of geometry whizzes work together to determine which of three differently shaped cylinders will have the greatest volume. Pupils cut out the three rectangles embedded in the plan, and tape them together to form a cylinder. From...

Lesson Planet: Curated OER

#### Insides and Outsides

Give small groups handfuls of unit cubes and then dare them to build as many rectangular prisms as possible using only 12 cubes. This engaging activity serves as an introduction to the volume of solid figures. In addition to volume,...

Lesson Planet: Curated OER

#### Geometry Practice: Classifying Solids #2

In this solids worksheet, students identify the characteristics of solids. They name solids and determine the number of faces. This three-page worksheet contains seventeen problems. Answers are listed on the last page.

Lesson Planet: Curated OER

#### Engineering 101

Make a structure too sturdy to fail. Scholars first watch a video and consider the reasons for the Tacoma Narrows bridge collapse. They take part in two engineering challenges, one using newspapers and the other using spaghetti sticks...

Lesson Planet: Curated OER

#### Multidimensional Thinking

Soil may seem flat, but it has dimension. A quick video lesson walks learners through the different dimensions of a sample of soil. Beginning with the linear measurements, the instruction describes the area and volume calculations as...

Lesson Planet: Curated OER

#### Thinking in the Three Dimensions

Discover different dimensions with paper folding. Pupils first read about zero, one, two, and three dimensions, and then learn about the fourth dimension, time. They then use origami to create models of shapes in three dimensions and use...

Lesson Planet: Curated OER

#### 2 and 3 Dimensional Shapes

Take a similar approach to three dimensions. Pupils develop the relationship between areas of similar objects and see how they relate to the ratio of the sides. Building upon area formulas, small groups put together volume formulas for...

Lesson Planet: Curated OER

#### Next Top Model

Create a world of similar models. The geometry and measurement unit uses real-world scenarios to create models of familiar buildings and rooms. Scholars work with blueprints and scale models to compare areas and volumes between the...

Lesson Planet: Curated OER

#### Whole Number Exponents: Teddy Bear Box

Five questionsâ€”multiple-choice, fill in the blank, and discussionâ€”make up an interactive that challenges scholars to mail a teddy bear using the smallest box possible without squishing it. A box with movable sides allows mathematicians...

Lesson Planet: Curated OER

#### What is a Constellation

Why do some stars in a constellation appear brighter than others? Using a get-up-and-move astronomy activity, scholars explore perspective and the appearance of constellations in the sky while developing an understanding of the...

Lesson Planet: Curated OER

#### Views and Elevations

The view depends upon location. A short video introduces the idea of views and elevations of 3-D figures. Using figures composed of cubes, the presenter creates their front, side, and plan views. The last figure requires the viewer to...
