Geometry worksheets, easiest first
Each sheet assumes the one above it is comfortable. Start where your child is, not at the top.- a 6 x 4 grid of unit squares Area by counting squares Child does: Count the unit squares inside each figure. Try this worksheet
- P = 2(8 + 5) Perimeter of a rectangle Child does: Add the four sides, or double the length plus the width. Try this worksheet
- A = 8 x 5 Area of a rectangle Child does: Multiply the two side lengths. Try this worksheet
- 12 + 5 + 8 + 5 Perimeter of triangles and quadrilaterals Child does: Add every side to find the distance around. Try this worksheet
- A = 48, one side 6 Missing side length Child does: Work backwards from the area or perimeter to the missing side. Try this worksheet
- acute / right / obtuse Types of angles Child does: Circle whether each angle is acute, right, or obtuse. Try this worksheet
- scalene / isosceles / equilateral Classifying triangles Child does: Name each triangle by its angles or by its sides. Try this worksheet
- a regular hexagon Lines of symmetry Child does: Write how many lines of symmetry each shape has. Try this worksheet
- V = 6 x 4 x 3 Volume of a rectangular prism Child does: Multiply the three edge lengths. Try this worksheet
- A = (b x h) / 2 Area of triangles and quadrilaterals Child does: Use the base and the perpendicular height. Try this worksheet
- 2(wd + wh + dh) Surface area and nets Child does: Add the areas of all six faces. Try this worksheet
- C = 3.14 x 10 Circumference of a circle Child does: Multiply pi by the diameter. Try this worksheet
- A = 3.14 x 5 x 5 Area of a circle Child does: Square the radius, then multiply by pi. Try this worksheet
- 20 x 12 less 4 x 3 Area of composite figures Child does: Split the figure, or subtract the missing piece. Try this worksheet
- x + 65 = 90 Complementary and supplementary angles Child does: Use the angle fact to find the angle marked x. Try this worksheet
- 6, 8, and the hypotenuse Pythagorean theorem Child does: Use a squared plus b squared equals c squared. Try this worksheet
A simple way through geometry
The early years are about covering and going round. Area starts as counting unit squares, not as a formula, because that is what area is — and perimeter starts as walking the edge. The formulas arrive once the counting has made them obvious, which is the order the standards use and the order these sheets follow.
Why this order works
The middle years widen the vocabulary. A child who has only measured rectangles meets triangles, parallelograms and trapezoids, learns to name angles and count folds of symmetry, and finds that a box has both a volume and a surface. The one mistake this stretch keeps producing is reading a slant side as a height, so those figures never label a slant side at all.
