Florida B.E.S.T. MA.6.GR.1.1
The Standard
Extend previous understanding of the coordinate plane to plot rational number ordered pairs in all four quadrants and on both axes. Identify the x- or y-axis as the line of reflection when two ordered pairs have an opposite x- or y-coordinate.

What This Standard Means
What Students Need to Do
- Students plot ordered pairs with positive and negative integers, fractions, and decimals on a coordinate plane. They identify the reflection axis when one coordinate changes to its opposite.
What Mastery Looks Like
- Students accurately plot integers, fractions, and decimals in every quadrant and on either axis. They compare two points and correctly identify the x-axis or y-axis as the reflection line.
Common Misconceptions
- Students often reverse the x- and y-coordinates or misread negative values. They may also confuse the reflection rules, naming the x-axis when x-values are opposites.
How to Assess It
- Give students the points A(-3, 2), B(3, 2), and C(-3, -2). Ask them to plot each point and name the reflection axis for AB and AC.

Ways to Teach It
Make a floor coordinate grid with tape, then have students stand at ordered pairs and move to reflected locations.
Ask students to explain why changing only the sign of x reflects a point across the y-axis.
Play reflection match with cards showing points, reflected points, and axis labels that students must group correctly.
Use a city map grid to plot locations, then place matching landmarks as reflections across a main road represented by an axis.
