What is the Geometry game?
Geometry is the math of shapes and space, and in the early grades that means four things: knowing shapes by their sides, measuring the distance around a shape, measuring the space inside it, and telling angles apart. This game gives a child short, tapped questions on each one, with the shape drawn on screen, so the idea is attached to a picture rather than a rule. The answer checks itself the moment you tap, and the working explains how it was found.
How do you play the Geometry game?
A shape appears with a question. For sides, count how many a triangle, pentagon or hexagon has. For perimeter, add up the four sides of the rectangle. For area, multiply its width by its height, or take half of a triangle's base times its height. For angles, decide whether what you see is acute, right or obtuse. Easy sticks to sides and small perimeters, Medium adds area and angles, and Hard brings in bigger numbers and triangle area.
Perimeter, area and angles from grade 3 to grade 6
These ideas arrive in order. Naming shapes and finding a simple perimeter come first, in second and third grade. Area of a rectangle follows in third and fourth grade, then angles and the area of a triangle in fourth and fifth. Because the difficulty is a button, one page carries a child across all of it. For the multiplication that area leans on, our times tables practice keeps those facts quick.
Frequently asked questions
What does the Geometry game practice?
The shapes, perimeter, area and angles that grades 3 to 6 learn. You count the sides of a shape, add up the sides of a rectangle for its perimeter, multiply width by height for its area, and tell an acute angle from a right or obtuse one. The answer checks itself and the working explains it.
What is the difference between perimeter and area?
Perimeter is the distance all the way around a shape, found by adding every side, so a rectangle is width plus height plus width plus height. Area is the space inside, found by multiplying width by height for a rectangle, or half of base times height for a triangle. The game drills both until the difference sticks.
What grade is this geometry for?
Shapes and perimeter start around second and third grade, area comes in third and fourth, and angles and triangle area land in fourth and fifth. Start on Easy for sides and simple perimeters, then move up as each idea becomes comfortable.
