How to help with this skill

First graders use drawings, objects, and number lines to understand small numbers and explain their thinking. Focus on accuracy before speed.

  • Identify the starting amount and the part being removed or compared.
  • Use counting back, a number line, or place-value regrouping.
  • Check by adding your answer to the amount removed.

Try this: Ask: What was there at the beginning, and what changed?
