Lesson 3 Plot More Points

- Let’s locate and name points on the coordinate grid.

Warm-up Notice and Wonder: Points with Zero

What do you notice? What do you wonder?

Coordinate grid. horizontal and vertical axis, 0 to 10 by ones. One point plotted at 0 comma 0

Activity 1 What’s the Point?

Problem 1

Partner A

Estimate the location of each point.

Point

Coordinates

$A$

$(5, 1)$

$B$

$(5, 2)$

$C$

$(5, 3)$

$D$

$(5, 4)$
Plot and label the points on the coordinate grid.
What do the points have in common?
Plot the point with coordinates $(5, 0)$ on the coordinate grid.

Problem 2

Partner B

Estimate the location of each point.
$A$
$(4, 3)$
$B$
$(5, 3)$
$C$
$(6, 3)$
$D$
$(7, 3)$
Plot and label the points on the coordinate grid.
What do the points have in common?
Plot the point with coordinates $(0, 3)$ on the coordinate grid.

Activity 2 Plotting Points Without a Grid

A point is labeled in the coordinate plane. Plot and label some other points. Explain or show your reasoning.
Can you plot $(1, 0)$ and $(0, 1)$ accurately? Explain or show your reasoning.

Practice Problem

Problem 1

Fill in the blanks with 4 different numbers between 0 and 10 and plot the points on the graph.
$($ $, 0)$ $($ $, 0)$
$($ $, 0)$ $($ $, 0)$
What do you notice about the points?

Locate the points $(1, 1)$ , $(2, 2)$ , $(3, 3)$ , and $(4, 4)$ on the graph.
What do you notice about the points?

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