Which level for which grade?
There are 8 levels, from naming shapes to the Pythagorean theorem. Each level has short lessons and a 5-question picture test; get 4 right to pass. Progress is saved on this device, so your child can come back and carry on.
| Level | Skill | Grade |
|---|---|---|
| 1 | Shapes and sides | 1–2 |
| 2 | Lines and angles | 4 |
| 3 | Triangles and quadrilaterals | 3–5 |
| 4 | Area and perimeter | 3–4 |
| 5 | Measuring angles | 4–7 |
| 6 | Area formulas and circles | 6–7 |
| 7 | 3D shapes and volume | 5–8 |
| 8 | Symmetry, moves and Pythagoras | 4–8 |
How to use the levels
- Find the starting level. Take the tests from level 1 until your child scores under 4. That is the level to work on.
- Learn it. Open the Learn links for that level: each lesson has pictures, a parent script and practice.
- Practice for a few days. Use the quizzes on the lesson pages and the geometry practice tool.
- Retake the test. 4 out of 5 passes the level. Move on to the next one.
Level 4 is the one to take slowly. Area and perimeter come back in every later level, inside triangles, circles and boxes.
Why the levels are in this order
Levels 1 to 3 build the words: shape names, lines, rays, angle types, and the families of triangles and quadrilaterals. Without them, later questions are hard to even read.
Levels 4 to 6 measure. Area by counting leads to the rectangle formula, which leads to triangles, parallelograms and circles. Angles go from naming to measuring to finding missing ones.
Levels 7 and 8 go into 3D and onto the grid: volume and surface area, then symmetry, transformations and the Pythagorean theorem. A child stuck there usually has a gap in level 4.
Tools that help with every level
The area and perimeter calculator draws any rectangle, triangle, trapezoid, circle or L shape to scale and shows every step. It helps with levels 4 and 6 especially.
Real objects matter too. Squared paper, a protractor, a ruler, tracing paper and a few boxes and cans make every level easier than a screen alone.

Questions parents ask
How do you learn geometry step by step?
Start with shape names and lines, then angles and shape families. Next come area and perimeter, angle measuring, area formulas and circles, then 3D shapes, transformations and the Pythagorean theorem.
What is the hardest part of geometry for kids?
Usually area vs perimeter in grade 3, protractors in grade 4, and the height in area formulas in grade 6. Drawing each one fixes most mistakes.
How long does it take to learn geometry?
It is spread over grades 1 to 8. Most children move through one or two levels a year, with short practice during each geometry unit.
Is progress saved?
Yes, passed levels are saved in this browser on this device. Nothing is sent to us.
Does it include the Pythagorean theorem?
Yes. Level 8 has symmetry, transformations and right triangles with a hidden side.
