■ CONCEPT SUMMARY & GUIDED NOTES: Let's build it together — How do you compare and order integers?
1The number farther to the left is always less; the number farther to the right is always greater.
  • To compare integers means to see which one is greater or less. On a number line, numbers get bigger as you go right and smaller as you go left. We'll walk through a worked example, try one together, then you'll try a few with hints right there when you need them.
2Worked Example — Watch me
  1. I will compare -7 and -5. They are both negative, so I look at the number line.
  2. -7 is 7 steps left of zero. -5 is only 5 steps left of zero.
  3. -7 is farther to the left, so -7 is the smaller number.
  4. I write -7 < -5. The open side of the symbol points to the bigger number, -5.
3Mathematical Word Bank
  • Compare and Order Integers (Comparar y ordenar enteros) — Use a number line to decide which integers are greater or less and place them in order.
  • Number line (Recta numérica) — A straight line where numbers are placed in order; numbers get smaller to the left and larger to the right.
  • Compare (Comparar) — To see if a number is bigger, smaller, or equal to another.
  • Order (Ordenar) — To arrange numbers by size, from least to greatest or greatest to least.
  • Greater than (Mayor que) — The > sign, showing one number is bigger.
  • Less than (Menor que) — The < sign, showing one number is smaller.
4Watch out
  • A common mistake in Compare and Order Integers is thinking that a negative number with a bigger digit is the bigger value — for example, believing -15 is greater than -8 because 15 is greater than 8. It's the opposite for negatives: the number farther to the left on the number line (farther from zero) is always the LESSER value, so -15 < -8. Before you submit, check your comparison against the number line, not just the digits.

SECTION 2 MATHEMATICAL WRITING & ERROR ANALYSIS
  1. 5 ERROR ANALYSIS

    Level 2 Extension — The Mis-Ranked Treasure Map

    1. 1Problem:Order the chest depths from least to greatest: -8 m and -15 m.
    2. 2Crew thinking:15 has bigger digits than 8, so -15 must be the bigger number. I'll list -8 first because it must be smaller.
    3. 3Crew answer:Least to greatest: -8, -15

  2. 6 ERROR ANALYSIS

    Find the Comparison Error

    1. 1Problem:Compare -3 and -8. Which is greater?
    2. 2Student thinking:8 is bigger than 3, so -8 must be greater than -3
    3. 3Student answer:-8 > -3
