🚀 Additional Notes:
- The
outer star orbit (clockwise) is for oral practice: students say problems like "13 minus 4 is 9", then move to next.
- This is
Set D, focusing on fact families from
11 to 18 using
addition and subtraction.
- The
One-Minute Test assesses speed and accuracy with basic facts.
---
🎯 Goal & Completion:
- Students set a
goal (e.g., how many they want to complete in one minute).
- Then write how many they
completed.
You can now fill in the blanks with the answers above!
