  1. Ren slides a boat sticker 2 units left and 3 units down, then flips it across the y-axis. Where does corner D, starting at (5, -1), end? Write it like (7, -3).

  2. Zee flips a rocket sticker across the x-axis, then slides it 6 units right and 5 units up. Where does corner D, starting at (-3, -2), end? Write it like (7, -3).

  3. Hold on, star! Ari flips a star sticker across the x-axis, then slides it 7 units left and 2 units down. Where does corner D, starting at (4, -5), end? Write it like (7, -3).

  4. Bo flips a butterfly design across the line x = 2, a mirror line up and down the grid. Corner D is at (5, 3). Where is D′? Write it like (7, -3).

  5. Esme flips a house design across the line x = -1, a mirror line up and down the grid. Corner D is at (-4, 2). Where is D′? Write it like (7, -3).

About this worksheet

Slide and flip a shape on the grid. Every version has 10 questions, and the answer key prints on the second page.

What your child will learn

  • I can slide a shape on the grid and write its rule, like (x, y) → (x − 4, y + 3).
  • I can flip a shape across the x-axis, the y-axis or a line like x = 2, and say which coordinate changes.
  • I can name the move from a shape and its image, undo a slide, and do a slide and a flip in the order given.

Standard: 8.G.A.3 (translations, reflections)

Words to know

translation (slide): Moving a shape without turning or flipping it. Every point moves the same way.

reflection (flip): A mirror image of a shape across a line.

line of reflection (mirror line): The line a shape is flipped across. Each point lands as far on the other side.

image: The shape after the move. Its corners get a prime mark: D becomes D′.

rule: How every point changes, written (x, y) → (x − 4, y + 3).

Common mistakes

Your child moved the shape the opposite way, for example right instead of left or up instead of down.

Your child moved the right way but lost the minus sign of a point left of 0 or below 0. Count the squares from 0 on the grid together.

Your child put the up-and-down move on the across number, or the other way round.

What to say

Ask: on the grid, which ways do the numbers get smaller?

Ask: which number in a point tells how far across?
