Improve students’ math skills relating to geometric shapes and angles.
Learning basic geometric shapes and the various angles required to build them is easier with this hands-on activity. Students learn the shape and how it’s created by building each form independently.
1. The teacher writes the names and descriptions of various geometric shapes on note cards
and places them in a bag. Note: When applicable and/or useful, include the angle degree in
the description. This will help students remember and learn the various degree angles and
how they apply to each shape.
2. Students are divided into pairs of two and given a LEGO Education Structures Set. (If there
are more students than sets, this activity can be done by dividing the Structures Set in half
and giving each group of students a portion of the set’s elements.)
3. The teacher pulls a name of a geometric shape from the bag. He/She then reads the
description and instructs the students to build the shape that has been described.
4. Students complete the build. Before moving onto the next shape, each build must be checked
by the teacher for accuracy.
5. Repeat Steps 3 through 4 until all shapes have been described and built.
1. What shapes were the easiest to build?
2. How do angles impact the building of a shape? (Example: Triangles can be obtuse or
Isosceles and still be triangles. Are other shapes able to change their appearance and still
remain a shape?)
3. Being able to move the beams allows for flexibility in design, can you think of how this is used
in the real world? (Example: Bridges are made up of numerous geometric shapes, but the
stability is found in the uniformity of the design. What would happen if bridges didn’t have
uniform geometric shapes?)
Pick a shape and test your students’ knowledge of it in the real-world. For example, Octagons. What real life objects use the octagon shape either as its design or as a component of its design? Instruct students to build their example.
