Mission Briefing — Put numbers in order

In this mission, you will put numbers in order. Sometimes you go from least to greatest. Sometimes you go from greatest to least.

Least to greatest

  • Start with the smallest number.
  • Numbers get bigger as you go.

Greatest to least

  • Start with the biggest number.
  • Numbers get smaller as you go.

Number line tip

  • Numbers on the right are bigger.
  • Numbers on the left are smaller.

Say the numbers out loud as you put them in order.

Training Run — Order numbers with a number line

Tap to play and pause.

Choose three numbers (like 12, 15, and 14). Say them out loud. Find the least number first, then the greatest. Now say the numbers in order. Check by imagining a number line: smaller goes left, bigger goes right. When you’re ready, trace and write a few numbers.
