Missouri STEM standards: hands-on mechanical engineering activities

Missouri Standards Mapping

Teachers can use Toyineer projects to address selected Missouri Learning Standards in Science and Mathematics through hands-on mechanical construction.

Alignment reviewed October 2026.

Executive summary

Teachers can use Toyineer projects to address Missouri academic standards by giving learners physical systems they can construct, observe and explain. Learners can observe repeatable motion and use its pattern to predict future movement (4.PS2.A.1), investigate balanced and unbalanced forces in a working mechanism (4.PS2.A.2), and use a physical lever mechanism as a model for how a simple machine can change effort force or the direction of force (4.PS3.C.1). The build also makes part-whole geometry concrete as learners compose and decompose two- and three-dimensional forms (1.GM.A.2) and examine shapes from different perspectives and orientations (1.GM.A.3). The completed toy provides visible, hands-on evidence for classroom discussion of force, motion, simple machines, geometry and spatial reasoning. Toyineer projects are hands-on engineering activities that teach mechanics, geometry, spatial reasoning and technical problem solving through the construction of working mechanical toys. Video instruction and clear assembly guides support independent and classroom use while keeping educator preparation minimal.

Standards and evidence.

These alignments use only the ordinary Toyineer construction process. They do not depend on a separate extension activity.

I. Missouri Learning Standards: Science — Motion, Forces & Energy

Grade 44.PS2.A.1

Make observations or measurements of an object's motion to provide evidence that a pattern can be used to predict future motion.

Rockers, followers, push rods and other constrained Toyineer parts move through repeatable paths. Learners can observe one motion cycle and predict the next position or direction of the moving component.

Grade 44.PS2.A.2

Investigate the effects of balanced and unbalanced forces on the motion of an object.

Toyineer mechanisms make balanced and unbalanced forces observable. Learners can compare a mechanism at rest with one under an applied force and explain why the resulting net force changes motion.

Grade 44.PS3.C.1

Use models to explain that simple machines can change the amount of effort force and/or the direction of force.

A Toyineer lever mechanism is a working physical model of a simple machine. Learners can operate it and trace how the lever and fulcrum redirect an applied input into controlled mechanical movement.

II. Missouri Learning Standards: Mathematics — Geometry and Measurement

Grade 11.GM.A.2

Compose and decompose two- and three-dimensional shapes to develop understanding of part-whole relationships and the properties of original and composite shapes.

Toyineer construction is a part-to-whole process: learners combine flat and folded components into subassemblies and then into one complete three-dimensional mechanical object.

Grade 11.GM.A.3

Recognize two- and three-dimensional shapes from different perspectives and orientations.

Learners repeatedly rotate and reposition blueprint parts and assembled components, connecting the same geometric form with different physical orientations and viewpoints.

Hands-on evidence for standards-aligned learning.

Teachers can use Toyineer projects to address these standards. Students also gain skill in their use of tools and appreciate the importance of accuracy in engineering.
