Esme slides a sled sticker 4 units left and 3 units up on a game map. One corner, D, starts at (2, 5). Where does D′ land? Write it like (7, -3).
Luz slides a bike sticker 3 units right and 8 units down on a game map. One corner, S, starts at (-4, 2). Where does S′ land? Write it like (7, -3).
Triangle CDF on Milo's kite design has corners C(1, 2), D(4, 6) and F(5, -1). Milo flips it across the x-axis. Where is D′? Write it like (7, -3).
Triangle SUV on Pia's sled design has corners S(3, -5), U(7, -2) and V(2, 4). Pia flips it across the x-axis. Where is U′? Write it like (7, -3).
Triangle CDF on Ren's butterfly design has corners C(-5, 4), D(-1, 7) and F(-3, 1). Ren flips it across the y-axis. Where is D′? Write it like (7, -3).
Triangle GHW on Tala's leaf design has corners G(2, -3), H(6, -7) and W(4, 2). Tala flips it across the y-axis. Where is H′? Write it like (7, -3).
Triangle SUV on Zee's umbrella design has corners S(-8, -2), U(-4, 5) and V(-1, -6). Zee flips it across the y-axis. Where is U′? Write it like (7, -3).
Ari's kite slides on a grid. Corner D moves from (2, 5) to (-1, 9). What is the slide's rule? Fill in (x, y) → (□, □), like x + 8, y - 1.
Bo's boat slides on a grid. Corner D moves from (-4, 1) to (2, -6). What is the slide's rule? Fill in (x, y) → (□, □), like x + 8, y - 1.
Esme's rocket slides on a grid. Corner D moves from (3, -2) to (8, 1). What is the slide's rule? Fill in (x, y) → (□, □), like x + 8, y - 1.

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

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)

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).

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.

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

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

What is the most common mistake with slide and flip a shape on the grid?

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

How can I help my child with slide and flip a shape on the grid?

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