This animation demonstrates how to construct triangles if you know the lengths of a triangle's 3 sides using a ruler and drafting compass.

Spatial visualization is the study of two- and three-dimensional objects and the practice of mental manipulation of objects. Spatial visualization skills are important in a range of subjects and activities like mathematics, physics, engineering, art and sports! In this lesson, students are introduced to the concept of spatial visualization and measure their spatial visualization skills by taking the provided 12-question quiz. Following the lesson, students complete the four associated spatial visualization activities and then re-take the quiz to see how much their spatial visualization skills have improved.

Students learn about two-axis rotations, and specifically how to rotate objects both physically and mentally about two axes. A two-axis rotation is a rotation of an object about a combination of x, y or z-axes, as opposed to a single-axis rotation, which is about a single x, y or z-axis. Students practice drawing two-axis rotations through an exercise using simple cube blocks to create shapes, and then drawing on triangle-dot paper the shapes from various x-, y- and z-axis rotation perspectives. They use the right-hand rule to explore the rotations of objects. A worksheet is provided. This activity is part of a multi-activity series towards improving spatial visualization skills. At activity end, students re-take the 12-question quiz they took in the associated lesson (before conducting four associated activities) to measure how their spatial visualizations skills improved.

Students learn how to create two-dimensional representations of three-dimensional objects by utilizing orthographic projection techniques. They build shapes using cube blocks and then draw orthographic and isometric views of those shapes—which are the side views, such as top, front, right—with no depth indicated. Then working in pairs, one blindfolded partner describes a shape by feel alone as the other partner draws what is described. A worksheet is provided. This activity is part of a multi-activity series towards improving spatial visualization skills.

Students will pick a character from whichever text they are currently reading and create a fake social media profile. This can be done digitally, though I have my students complete it on poster board. There are several templates I have come across that match up with the various forms of social media in the project instructions.

Students should NOT use real social media sites to create their profiles.

In this lesson, students will use manipulatives to solve addition problems within 10 that involve putting together two groups of objects.

In this lesson, students work together to create a "human number line" by ordering themselves from least to greatest after being assigned numbers by the teacher. They then apply their learning to personal number lines.

This resource is from Tools4NCTeachers. This file contains a set of 3 tasks (including scoring rubric and recording sheets).  The tasks may be used for instruction or assessment.The focus of standard G.1 is on recognizing/drawing 2D shapes and recognizing/describing 3D shapes.  Please remix this resource to help create additional tasks - especially for 3D shapes!

In this lesson, students "notice" and "wonder" as they view a series of real world photographs. Students use a variety of representations to solve the problem depicted in the photographs.
