Hands-on from the start: folding paper, building shapes, measuring real objects, then connecting those experiences to formulas.
A hands-on guide for teaching first graders to identify, describe, and compare 2D and 3D shapes by their attributes — sides, corners, faces, and edges. Includes shape hunts, building activities, and parent-child dialogue.
A play-based guide to teaching shape recognition to Pre-K and early kindergarten children (ages 3-5). Activities for identifying, sorting, and finding shapes in the real world.
Most kids can name a circle and a square. But real shape understanding means knowing why a shape is what it is, its properties, not just its appearance. Here is how to build genuine geometry understanding from the start.
A clear explanation of perimeter, the distance around a shape. What it means, how to find it, and how it differs from area.
Most kids mix up area and perimeter because they learn both at the same time without understanding what each one measures. Here is how to teach them as separate concepts that make sense on their own.
Eighth graders must understand translations, rotations, reflections, and dilations — and use them to prove congruence and similarity. This guide gives homeschool parents a hands-on teaching sequence for transformation geometry at the 8th-grade level.
Symmetry and transformations are the foundation of geometric reasoning. Here is how to teach reflections, rotations, and translations so your child sees geometry as movement, not just static shapes.
Pi is one of the most famous numbers in math, but what actually is it? A clear explanation of π, where it comes from, and why it matters.
Circles introduce pi, one of the most fascinating numbers in math. Here is how to teach circumference and area so your child understands where π comes from and why the formulas work.
