South Carolina STEM standards: hands-on mechanical engineering activities

South Carolina Standards Mapping

Teachers can use Toyineer projects to address selected South Carolina Science and Mathematics standards through hands-on mechanical construction.

Alignment reviewed October 2026.

Executive summary

Teachers can use Toyineer projects to address South Carolina academic standards by giving learners physical systems they can construct, observe and explain. Learners can compare how pushes and pulls affect motion (K-PS2-1) and investigate balanced and unbalanced forces in a working mechanism (3-PS2-1). South Carolina's current mathematics standards also provide a direct geometry connection through identifying and describing points, lines, line segments, intersecting lines, perpendicular lines and parallel lines in two-dimensional figures (3.MGSR.3.2). The completed toy provides visible, hands-on evidence for classroom discussion of force, motion, 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. 2021 South Carolina College- and Career-Ready Science Standards: Forces and Motion

KindergartenK-PS2-1

Plan and conduct an investigation to compare the effects of different strengths or different directions of pushes and pulls on the motion of an object.

During ordinary assembly and testing, learners push and pull moving components and can compare how changes in direction or relative effort affect the resulting motion.

Grade 33-PS2-1

Plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object.

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

II. 2025 South Carolina College- and Career-Ready Mathematics Standards: Geometry and Spatial Reasoning

Grade 33.MGSR.3.2

Identify, describe, and draw points, lines, line segments, rays, intersecting lines, perpendicular lines, and parallel lines; identify these in two-dimensional figures.

Toyineer blueprint parts contain visible line segments, intersections, parallel edges and perpendicular relationships that educators can identify directly during ordinary construction.

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.
