Classifying shapes: printable worksheets
Sort shapes into categories, decide whether statements about shape categories are true and fill in a hierarchy of quadrilaterals.
Sample worksheet
The first 2 problems of a real worksheet, made the way the builder makes it. Open it in the builder to change the number of problems, the difficulty and the layout, then print.
1.
All trapezoids are quadrilaterals. True or false?
- True
- False
2.
No right triangle is a triangle. True or false?
- True
- False
Show answers
1.True: Every shape with 4 sides is a quadrilateral.
2.False: A right isosceles triangle is both a right triangle and a triangle.
What students practise
I can sort and name shapes by their sides, angles and parallel lines.
Students use sides, angles and parallel and perpendicular lines to name, compare and classify two-dimensional shapes, see that a category shares its attributes with every subcategory, and find lines of symmetry.
Key words
- quadrilateral
- a shape with four straight sides
- parallel
- lines that stay the same distance apart and never cross
- perpendicular
- lines that cross to make a right angle
- right angle
- a square corner
- line of symmetry
- a fold line that makes the two halves match
Common mistakes
- Calls a turned square a diamond and says it is not a square.
- Draws or names a line without arrows, as if it were a segment.
- Thinks a square cannot also be a rectangle.
Standards
Common Core State Standards this worksheet practises.
- 5.G.B.3: Understand that attributes belonging to a category of two-dimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles. (unverified)
- 5.G.B.4: Classify two-dimensional figures in a hierarchy based on properties. (unverified)
