If we stack up all the cross sections of a figure, does it create the figure? Pupils make the connection between the complete set of cross sections and the solid. They then view videos in order to see how 3D printers use Cavalerie's...

Explore the relationship between 2D and 3D shapes by having your class view representation of shapes and investigate their symmetry. They will create a solid object from diagrams and describe the reflection or rotational symmetry. In the...

Creating with an app is nice. But, creating with an app and being able to print and use your creation is great! This tool provides the opportunity to hone the skills related to spacial awareness, three-dimensional thinking, creativity,...

In this math instructional activity, students examine 4 pictures of 3D objects and write the name of each. Students then study 3 pictures and figure the number of faces, edges and vertices on each.

Students investigate the creation of three dimensional drawings. In this geometry lesson, students analyze and complete orthographic drawings. They Cabri software to manipulate and move the drawings around.

Young scholars investigate orthographic drawings. In this geometry lesson plan, students identify properties of three dimensional drawings in space. They solve problems using volume and area formulas.

How  does the shape of the surface of water in a container change as water leaks out? After tackling this question, learners take part in a similar activity with more complex figures.

Sew up pupil interest with an engaging, hands-on instructional activity. Learners first design a sports bag given constraints on the dimensions of fabric. They then evaluate provided sample responses to identify strengths and weaknesses...

"Fore!" All right, no one really yells this out in miniature golf, but this well-defined activity will have your charges using lots of numbers in their unique design of a miniature golf hole. Included in the activity criteria is the...

In this exploring projective geometry worksheet, students use computer software for instruction, then answer 9 questions about 3D drawings.

Emerging engineers perform pre-lab calculations in this first of a three-part activity on model building. They determine the forces of tension and compression in a truss. After completion of the worksheet, pupils will draw a draft of...

Students participate in a series of hand-on, online, and multimedia activities to examine 2 dimensional and 3 dimensional shapes. They describe common geometric solids. They construct rectangular prisms using straws and ribbon.

Stop the summer lag with a set of second grade Common Core based math practice sheets. Learners fill in hundreds charts with missing numbers up to 1,000. They practice writing numbers in standard, expanded, and word form. Children also...

Ask elementary students to explore shapes in everyday objects. They will discuss the elements of design and describe the shapes they see in visual images. Students will then design and "build" a new 3D shape. Finally they will show and...

Learners investigate nets as they relate to volume and area. In this geometry lesson, students use nets as a visual to deepen their understanding of surface area and volume of objects. They make conjectures about different objects and...

Students create three dimensional shapes using concept maps. In this geometry lesson, students investigate the impact of mental schemas on humans. They collect data on this topic and plot their data on a coordinate plane.

Agriculture is truly a math-based profession! Help the dairy farmer determine the supplies needed to complete his barn. Using given dimensions, learners build equations and use units to determine the correct amount of materials.

Create and investigate nets for solid shapes with your class. They identify the different parts and faces of each polygon and solid then calculate the surface area and volume of cones. They use circle sectors of varying sizes to build...

Third graders use a number of problem solving strategies in this unit of lessons. They determine how to draw and model three-dimensional objects, use co-ordinate systems, determine probability of events, and identify paths of simple...

Get learners' minds rotating and reflecting while looking for symmetry. Pupils investigate figures to determine the number of lines of symmetry and if the figure has rotational symmetry. Classmates work together in groups to find out the...

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

Students explore recognizing, counting and sequencing numbers 1-10. In this primary math introduction lesson, students participate in 6 computer sessions that integrate short films, music and drawing in order to bring beginning math...

Students investigate how to draw and classify two and three dimensional figures (squares, triangles, rectangles.)

Third graders examine two-dimensional objects and create a 3-D image of the object. They make models of the Taj Mahal and buildings in Delhi.
