3.G.A.1 Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.Practiced in: Lines, Triangles & Quadrilaterals

4.MD.A.3 Apply the area and perimeter formulas for rectangles in real world and mathematical problems.

4.MD.C.6 Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure.Practiced in: Angles
4.MD.C.7 Recognize angle measure as additive. When an angle is decomposed into non-overlapping parts, the angle measure of the whole is the sum of the angle measures of the parts. Solve addition and subtraction problems to find unknown angles on a diagram in real world and mathematical problems, e.g., by using an equation with a symbol for the unknown angle measure.Practiced in: Tessellations, Angles

How to use these games in class
🚀 Starter (5 minutes)
Project 3D Shapes and spin a solid on the board. Ask the class to count its faces, edges and corners before you reveal the numbers.
🧩 Station (10–15 minutes)
Pairs take a tablet or Chromebook with Angles: one student sets an angle with the protractor, the other estimates it first and checks.
🏠 Homework
Share the Coordinate Grid link and ask students to plot a treasure hunt and write down the (x, y) points they used.
Questions teachers and parents ask
Which geometry game should I start with?
For kindergarten to 2nd grade start with 3D Shapes or Shapes & Symmetry. For grades 3 to 5 try Lines, Triangles & Quadrilaterals or Perimeter & Area, and add Angles in grade 4. For grades 6 to 8 try Triangle & Parallelogram Area, Surface Area, Volume or Pythagorean Theorem.
What geometry do students learn in each grade?
In Common Core, kindergarten to grade 2 name, build and compare shapes. Grade 3 groups shapes by attributes, grade 4 adds lines, angles and symmetry, and grade 5 adds volume and the coordinate plane. Grade 6 covers area, surface area and volume, grade 7 scale drawings, constructions and circles, and grade 8 transformations, congruence, similarity and the Pythagorean theorem.
Are these math games free, and do students need an account?
Yes, they are free. Students do not need an account, a download or an email address: open the link in a browser on a Chromebook, tablet, laptop or phone and play.
How do the levels, missions and stars work?
Most games have three levels, so a student can start easy and move up: a free play mode where nothing can go wrong, missions that award up to 3 stars, and a short timed challenge with no penalties.
