Nets & Views

Fold nets into solids and picture top, front and side views

What your child practises

Matching flat nets to prisms and cylinders, working out what the parts of a net measure, and picturing an object from above, the front and the side.

Alberta Curriculum learning outcome: SS2, SS5 · nets of right prisms and cylinders, and top, front and side views of objects built from rectangular prisms

Sample questions

A taste of this unit. In the app, questions change every time and get easier or harder to match your child.

  1. Question 1

    In a net of a cylinder, the length of the rectangle matches the…

    • circumference of the circle
    • diameter of the circle
    • area of the circle
    • radius of the circle
    Show answer

    circumference of the circle

    Hint: The rectangle wraps once around the circle's edge.

  2. Question 2

    In a net of a cylinder, the width of the rectangle matches the…

    • area of the circle
    • circumference of the circle
    • height of the cylinder
    • radius of the circle
    Show answer

    height of the cylinder

    Hint: The rectangle's other side runs from the bottom to the top of the cylinder.

  3. Question 3

    Three cubes sit in a row, and a fourth cube sits on top of the left end cube. You look at it from the right-hand side. What do you see?

    • a column of 4 squares
    • a column of 2 squares
    • a row of 3 squares
    • a single square
    Show answer

    a column of 2 squares

    Hint: From the end, the rows line up behind each other. The tallest stack is 2 cubes high.

  4. Question 4

    A can has a diameter of 11 cm. In its net, one side of the rectangle wraps around the circle. How long is that side? Use π ≈ 3.14 and round to 1 decimal place.

    answer boxcm

    Show answer

    34.5 cm

    Hint: Circumference = π × diameter ≈ 3.14 × 11 = 34.54, which is 34.5 cm to one decimal place.

  5. Question 5

    A square pyramid's net has how many triangles?

    • 5
    • 4
    • 2
    • 1
    Show answer

    4

    Hint: One triangle rises from each side of the square base.

  6. Question 6

    A prism has a base with 5 sides. How many faces does it have in all?

    answer box

    Show answer

    7

    Hint: 5 rectangles go around the sides, plus 2 bases: 5 + 2 = 7.
