Identifying and naming common 2D shapes: triangle, square, rectangle, circle, pentagon, hexagon, octagon.
Where your child meets this in real life: Recognising shapes in road signs, buildings, tiles, and everyday objects
SEAGReady breaks name 2d shapes into 3 steps, taught in order so each skill builds on the last.
Identify and name triangle, square, rectangle, and circle from visual examples
Identify and name pentagon, hexagon, and octagon by counting sides
Recognise and name shapes correctly regardless of rotation or unusual positioning
Three free sample questions from our name 2d shapes course. Every question comes with a full explanation, and hints that guide without giving the answer away.
What is the name of the three-sided shape shown?
The STOP-sign outline shown is an octagon. How many sides does it have?
The shape shown is balanced on a corner. It has four equal sides and four right angles. What is its most specific mathematical name?
This is the exact interactive worked example your child sees in SEAGReady. Step through it and watch the method build up.
A road sign has an outline with 3 straight sides.
What is the name of this shape?
3-sided shape = ?
Count each straight edge of the shape
Step 1 of 3
A road sign has an outline with 3 straight sides.
What is the name of this shape?
The shape is a triangle.
The key insight: Count the sides to name the shape - 3 sides always means triangle!
Common mix-up: Calling it a 'pyramid'. A pyramid is a 3D shape. Flat shapes with 3 sides are triangles.
These are the misconceptions we see most often in name 2d shapes, including the ones our practice questions are specifically designed to catch.
SEAGReady finds the exact step where your child gets stuck, teaches it with worked examples like the one above, and brings it back for review so it sticks.
