Grade 5 Prisms, Pyramids & Moves worksheet
from Gradelings · Name: ______________________
How to explain it
- A prism has two matching bases. A pyramid has one base and triangle sides meeting at a point.
- The base shape names the solid: a triangular prism, a square pyramid.
- A slide, a flip and a turn move a shape without changing its size.
Example: A solid has a square base and four triangle faces that meet at a point. What is it? One base and a point on top means a pyramid. The base is a square. Answer: A square pyramid
Question 1
How many vertices (corners) does a triangular prism have?
answer box
6
Hint: Each base has as many corners as it has sides, and a prism has 2 bases.
Question 2
Point A was translated (slid) to A′. How many units up did it move?
answer box
2
Hint: Count the grid squares from A to A′ going straight up or down only.
Question 3
What shape are the faces that meet at the top point of a pyramid?
- rectangles
- circles
- pentagons
- triangles
triangles
Hint: The faces of a pyramid rise from the base edges and meet at one point, the apex.
Question 4
Which of these is a prism?
- rectangular prism
- sphere
- cylinder
- cone
rectangular prism
Hint: A prism has 2 matching flat bases, and all its other faces are rectangles. It has no curved surfaces.
Question 5
How many faces does a rectangular prism have?
answer box
6
Hint: A prism has 2 bases plus 1 rectangular face for each side of the base.
Question 6
Which describes the translation from A to A′?
- 4 units right, 2 units down
- 2 units right, 4 units down
- 4 units right, 2 units up
- 4 units left, 2 units down
4 units right, 2 units down
Hint: Count how far A moves across (right or left) first, then how far it moves up or down.
Question 7
A 3D object has 1 pentagon base and 5 triangular faces that meet at a point. What is it?
- pentagonal pyramid
- triangular pyramid
- octagonal pyramid
- pentagonal prism
pentagonal pyramid
Hint: One base with triangles meeting at a point (the apex) makes a pyramid. Name it after the shape of its base.
Question 8
Which single transformation changes the first letter into the second?
p → q- translation (slide)
- reflection (flip)
- rotation (turn)
reflection (flip)
Hint: A translation slides (no turning or flipping). A reflection flips over a line, like a mirror. A rotation turns around a point.
Question 9
A shape slides 4 units to the right without turning or flipping. What transformation is this?
- translation (slide)
- reflection (flip)
- rotation (turn)
translation (slide)
Hint: A translation slides (no turning or flipping). A reflection flips over a line, like a mirror. A rotation turns around a point.
Question 10
How many faces does a triangular pyramid have?
answer box
4
Hint: A pyramid has 1 base plus 1 triangular face for each side of the base.
