About This Set
This printable trimino is a self-checking states of matter puzzle for grades 2–4. Students match each prompt to its answer along the edges of the triangular pieces — the edge reading condensation connects to gas→liquid. Because every answer sits on a neighboring piece, students check their own matches as they build; there's no answer key to hand out.
At a glance: 12 triangular pieces · 1–2 students · prints in color or black & white.
How to use it in class: Drop it at a station for early finishers or a quiet rotation. It works solo or with a partner, and since it's self-checking you can run it while you're with another group.
