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.
Sean sees a road sign near the Giant's Causeway with 3 straight sides. What is the name of this shape?
Answer: A. Triangle
Count the sides: 1, 2, 3 sides. A shape with 3 straight sides is called a triangle. The prefix 'tri' means three.
Stuck? Start here: Count the number of sides on the shape.
Conor sees a STOP sign near his school in Belfast. A STOP sign is an octagon. How many sides does an octagon have?
Answer: D. 8 sides
The prefix 'octa' means 8. Think: octopus has 8 legs. So an octagon has 8 sides.
Stuck? Start here: Think of an octopus - how many legs does it have?
Niamh sees a shape balanced on one of its corners, looking like a diamond. It has 4 equal sides and 4 right angles. What shape is it?
Answer: B. Square
Check the properties: - 4 equal sides ✓ - 4 right angles ✓ This is a square. Turning a shape does not change what it is. 'Diamond' is not a proper shape name - it's just a square rotated 45 degrees.
Stuck? Start here: What are the properties? Count the sides and check the angles.
This is the exact interactive worked example your child sees in SEAGReady. Step through it and watch the method build up.
Aoife is looking at shapes on road signs in Belfast. She sees a sign with 3 straight sides.
What is the name of this shape?
3-sided shape = ?
Step 1 of 3
Aoife is looking at shapes on road signs in Belfast. She sees a sign 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!
Watch out: 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.
