Coordinate Grid Concepts and Scales

The video tutorial guides 6th-grade students through setting up a coordinate plane on a 20x20 grid, placing the origin at the center, and plotting points. It covers adjusting scales for different coordinate ranges, plotting decimal coordinates, and determining appropriate scales for axes. The tutorial emphasizes understanding the coordinate system and accurately plotting points.

What is the center point of a 20 by 20 coordinate grid?

• (0, 0)

• (10, 10)

• (20, 20)

• (5, 5)

If each grid line represents one unit, what is the coordinate of a point 5 units to the left of the origin?

• (0, -5)

• (0, 5)

• (5, 0)

• (-5, 0)

How would you plot the point (3, 2) on a coordinate grid?

• Move 3 units right and 2 units up

• Move 2 units left and 3 units down

• Move 3 units left and 2 units down

• Move 2 units right and 3 units up

What scale should be used for the y-axis if the highest point is 35 and the lowest is -40?

• 1 unit per grid line

• 2 units per grid line

• 4 units per grid line

• 5 units per grid line

Which point is located at (9, -40) on a coordinate grid?

• 9 units right, 40 units up

• 9 units left, 40 units down

• 9 units right, 40 units down

• 9 units left, 40 units up

What is the scale for the x-axis if the largest x-coordinate is 0.8?

• 0.1 unit per grid line

• 0.8 unit per grid line

• 0.5 unit per grid line

• 1 unit per grid line

How would you plot the point (0.1, 4) on a coordinate grid with a scale of 0.1 for the x-axis?

• Move 0.1 units left and 4 units down

• Move 1 unit right and 4 units up

• Move 1 unit left and 4 units down

• Move 0.1 units right and 4 units up

What is the appropriate scale for the x-axis if the range is from -14 to 14?

• 5 units per grid line

• 2 units per grid line

• 1 unit per grid line

• 10 units per grid line

If the y-axis range is from -4 to 2, what scale should be used?

• 1 unit per grid line

• 2 units per grid line

• 0.5 unit per grid line

• 5 units per grid line

How would you plot the point (-8, -4) on a coordinate grid with a scale of 2 for the x-axis?

• Move 8 units left and 4 units down

• Move 4 units right and 8 units up

• Move 8 units right and 4 units up

• Move 4 units left and 8 units down
