In this 2 and 3 dimensional figures worksheet, students determine whether given shapes are regular or irregular. A reference web site is given for additional activities.

Young mathematicians classify squares according to attributes. They sort squares according to specific attributes. Learners explore squares in repeating patterns and order squares according to size. Engaging extension activities are...

Students explore intersecting lines. In this intersecting lines lesson plan, students investigate shapes consisting of parallel, perpendicular, and similar lines. Students investigate these lines in shapes around them.

Learners study facial symmetry. They explore lines of symmetry, and create illustrations with multiple lines of symmetry.

In this formulas instructional activity, students write the area, perimeter, and volume formulas of 17 2D and 3D polygons.  Students list properties of various types of triangles and the metric conversions for metric units.

In this math worksheet, students study 5 basic geometric shapes. Students write a description for each, naming the shape, telling about the edges, the lengths and the corners.

In this shape recognition worksheet, students study each of the shapes and then write the names of the two-dimensional polygons on the lines.

In this math and language arts worksheet, students examine 15 words in a word bank which pertain to geometric shapes. Students find the words in a word search puzzle.

Discuss the properties of 2D and 3D shapes in order to help learners understand the concept. Learners will participate in an interactive whiteboard lesson plan to develop understanding of 2D and 3D shapes.

Students use their understanding of 3D on 2D to make a representation of a 4D form on paper.

Learners practice coordinates and measurements, develop 2D, 3D topological map, construct grid with string on real surface, establish "level" fixed point for measurements, take and record data points of elevation, and enter data on...

Students explore the relationship and impact of information technology and digital media in the business arena. They create an interactive digital presentation which includes web links, links (buttons) to jump to different slides,...

Elementary school learners investigate the attributes of a square. They discover that squares are polygons and examine squares found in everyday life. They concentrate on connecting the word, square, with the shape. As an...
