What kids do

“Number puzzles for a guest teacher day. Show your thinking in the space next to each one.”

Printed on the sheet:

  1. 1. I am a two-digit number. My digits add to 9 and my tens digit is twice my ones digit. What am I?
  2. 4. What comes next? 1, 4, 9, 16, 25,
  3. 5. What comes next? 3, 6, 12, 24,
  4. 6. In a magic square every row adds to 15. A row has 8 and 1. What is the third number?
  5. 7. A number times itself is 81. What is the number?
  6. 9. Make up a mystery number puzzle for a classmate.

Teacher tip

Include a bonus puzzle for early finishers.

How to use it

  • Leave clear, short directions and an answer key where the sub can find it.
  • Update the folder each grading period, as routines and students change.
  • Keep a stack of copies in a labeled tray so you can grab one without stopping the lesson.

Watch for

Activities that need too much teaching. A sub day is for review, not new lessons.

Talk about it

  • What should we tell our guest teacher about our class?
  • What is one thing that went well this week?

Take it further

Have kids write a thank-you note to the sub at the end of the day.

US Letter, prints well in black and white. Free for home and classroom use: print as many copies as you need.
