18. Reasoning Mind Academy: Coordinate Grid Great! So, how to I plot a point and name it?! Let’s try some coordinate grid EXAMPLES.

19. Reasoning Mind Academy: Coordinate Grid Example 1) Graph point R at (4, 5) on the grid provided below. Step 1: Draw and number the and on grid paper. Step 2: Identify the and. Step 3: ALWAYS BEFORE YOU UP OR DOWN!

20. Reasoning Mind Academy: Coordinate Grid Example 1) Graph point R at (4, 5) on the grid provided below. Step 1: Draw and number the x-axis and y-axis on grid paper. Step 2: Identify the x-coordinate and y-coordinate. Step 3: ALWAYS RUNBEFORE YOU JUMP UP OR DIVE DOWN!

21. Reasoning Mind Academy: Coordinate Grid Example 1) Graph point R at (4, 5) on the grid provided below. First, move to the right or left from the origin using the to locate the x-coordinate. Then, move up or down from the x-axis using the to locate the y- coordinate. Step 4: Mark a and it with its coordinates or a letter! (If you have a FIRST & LAST name, make sure the point does too! )

22. Reasoning Mind Academy: Coordinate Grid Example 1) Graph point R at (4, 5) on the grid provided below. First, move to the right or left from the origin using the x-axis to locate the x-coordinate. Then, move up or down from the x-axis using the y-axis to locate the y- coordinate. Step 4: Mark a point and name/label it with its coordinates or a letter! (If you have a FIRST & LAST name, make sure the point does too! )

23. Reasoning Mind Academy: Coordinate Grid Example 2) If given a data table, we can also graph points to create a line graph! Use the steps we learned in example one to plot your points on a line graph. xDay13579 yHeight (cm) 48101114
