Florida B.E.S.T. MA.6.AR.1.2
The Standard
Translate a real-world written description into an algebraic inequality in the form of x > a, x < a, x ≥ a or x ≤ a. Represent the inequality on a number line.

What This Standard Means
What Students Need to Do
- Students find the unknown quantity, boundary number, and limit words in a situation. They write the inequality, then graph it with the correct circle and shading.
What Mastery Looks Like
- Students identify the boundary value and decide whether it is included. They choose the correct symbol, place the right endpoint, and shade in the correct direction.
Common Misconceptions
- Students often reverse the inequality symbol or shade the wrong side of the number line. They may treat “at least” as exclusive or use a closed circle for “more than.”
How to Assess It
- Give this exit ticket: “Riders must be at least 48 inches tall. Let h represent height. Write an inequality and graph it.”

Ways to Teach It
Place phrase cards like “more than 7” on a floor number line, then mark each boundary with an open or closed hoop.
Discuss: “A backpack may weigh no more than 20 pounds.” Which symbol and endpoint belong, and what words prove your choice?
Play a matching game with description, inequality, and number-line cards; students must explain each completed set before keeping it.
Use local ride-height rules or sports age limits to write inequalities and draw number-line graphs.
