Perimeter Practice – 2-Player Board Game is an interactive, turn-based math game that helps students master perimeter through a fun classroom board-game experience. Players take turns solving perimeter problems—using both visual shapes (rectangles, triangles, and regular polygons) and word-problem style prompts—to earn the right to roll the dice and move around the board.
Perimeter Word Problem Game – Multiplayer is an engaging, classroom-ready math game that helps students practice perimeter through realistic word problems involving rectangles and squares. Students read a scenario, choose the correct unit (inches, centimeters, feet, meters, or yards), and calculate the total distance around an object or space. With a built-in timer and rotating turns, this game keeps learners focused while building accuracy and confidence with perimeter skills.
Perimeter – Find Missing Total is an interactive, classroom-ready math game that helps students practice perimeter by solving missing length and missing total problems. Players use the equation Total Perimeter − Sum of Known Sides = Missing Length to find unknown values on shapes and real-world scenarios.
The GeoGen Shape Generator is a premium teacher-only math tool designed to help educators quickly create high-quality geometry, area, and perimeter practice materials. Registered teachers gain access to a powerful shape-building tool that generates custom rectangles and polygons with accurate side-length labels, optional missing sides, and calculated area and perimeter values.
Math Millionaire is an engaging, two-player educational math game that helps students master percent, interest, and real-world financial math skills through fast-paced, game-show-style gameplay. Players take turns answering timed multiple-choice math questions to climb a prize ladder that reaches $1,000,000.
Find the Total Area of Two Rectangles (3.MD.C.7) is a timed, interactive math game where students solve area problems by building and analyzing rectangles like a “garden plan.” Players work with adjacent rectangles and L-shaped figures, using the distributive property and missing side length reasoning to find the area of each part and the total area.
Area & Perimeter Tic-Tac-Toe is an interactive, two-player math game that blends classic tic-tac-toe strategy with Grade 3 measurement concepts aligned to 3.MD.C.8. Players take turns selecting an empty square on a 3×3 board, then must correctly solve an area and/or perimeter challenge to earn the right to place their X or O. If a player answers incorrectly (or runs out of time), they do not place a mark and the turn passes to the other player.
In this Earth Science Lab, I have my students design an experiment that determines which sediment type is the most porous and which sediment type is the most permeable. This is a common design that my students come up with. There are others, but this one works well. For the lab, go to https://earthscience.xyz/content/porosity-and-permeability-lab.
MinuteEarth, a youtube channel demonstrates how a river goes from straight to meandering. Learn some basic concepts of erosion, deposition, and stream formation in this video. This science video also talks about river landforms.
