Lesson 1 Explore the Coordinate Grid

    • Let’s explore the coordinate grid.

Warm-up Notice and Wonder: The Grid

What do you notice? What do you wonder?

Coordinate grid. horizontal and vertical axis, 0 to 10, by 1's.

Activity 1 Can You Draw It: Shapes on the Coordinate Grid

  1. Play three rounds of Draw My Shape using the three sets of cards from your teacher.

    For each round:

    • Partner A choose a card—without showing your partner—and describe the shape on the card.

    • Partner B draw the shape as described.

    • Partner A reveal the card and partner B reveal the drawing.

    • Compare the shapes and discuss: What’s the same? What’s different?

    Round 1

    Round 2

    blank 10 by 10 grid

    Round 3

    Coordinate grid. horizontal and vertical axis, 0 to 10 by ones.

  2. Look at partner B’s drawings for each round. When does partner B’s drawing look most like the shape on the card? Explain why you think that is so.

Activity 2 Guess Which One: Shapes on the Coordinate Grid

Problem 1

Play a round of Guess Which One.

  • Sit next to your partner.

  • Partner A: Mentally choose a shape card without indicating which shape card you chose.

  • Partner B: Ask yes or no questions to determine which shape card partner A has chosen.

  • Switch roles and play another round of Guess Which One.

A
Rectangle, plotted on coordinate grid. vertices at 2 comma 1, 2 comma 3, 9 comma 1, 9 comma 3. 
B
Rectangle, plotted on coordinate grid. vertices at 2 comma 1, 2 comma 8, 4 comma 1, 4 comma 8. 
C
Rectangle, plotted on coordinate grid. vertices at 3 comma 5, 3 comma 7, 8 comma 5, 8 comma 7. 
D
Rectangle, plotted on coordinate grid. vertices at 3 comma 3, 3 comma 7, 5 comma 3, 5 comma 7. 
E
Rectangle, plotted on coordinate grid. vertices at 2 comma 7, 2 comma 9, 9 comma 7, 9 comma 9. 
F
Rectangle, plotted on coordinate grid. vertices at 3 comma 1, 3 comma 8, 5 comma 1, 5 comma 8. 
G
Rectangle, plotted on coordinate grid. vertices at 2 comma 1, 2 comma 6, 4 comma 1, 4 comma 6. 
H
Rectangle, plotted on coordinate grid. vertices at 7 comma 7, 7 comma 10, 9 comma 7, 9 comma 10. 
I
Rectangle, plotted on coordinate grid. vertices at 2 comma 4, 2 comma 6, 9 comma 4, 9 comma 6. 
J
Rectangle, plotted on coordinate grid. vertices at 2 comma 4, 2 comma 5, 7 comma 4, 7 comma 5. 
K
Rectangle, plotted on coordinate grid. vertices at 8 comma 6, 8 comma 10, 10 comma 6, 10 comma 10. 
L
Rectangle, plotted on coordinate grid. vertices at 3 comma 5, 3 comma 7, 7 comma 5, 7 comma 7. 

Problem 2

Diego and Kiran were playing a round of Guess Which One. These are the last two shapes. What question can Kiran ask to determine which shape is the one that Diego picked?

Rectangle, plotted on coordinate grid. vertices at 3 comma 1, 3 comma 8, 5 comma 1, 5 comma 8. 
Rectangle, plotted on coordinate grid. vertices at 2 comma 1, 2 comma 8, 4 comma 1, 4 comma 8. 

Practice Problem

Problem 1

Coordinate plane. Rectangle R, 0 comma 2, 0 comma 5, 7 comma 2, 7 comma 5. Point, P, 8 comma 9.

  1. How would you describe the point labeled ?

  2. How would you describe the rectangle R?
