teacher note Teacher note: Group by Zodiac signs

This “unplugged” activity will give students practice on “tracing through” elif statements.


Twelve students stand in line side-by-side holding up signs with zodiac sign dates on them. The rest of the students start at one end of the line, and, for each sign, check to see if their birthday falls within that zodiac sign period. If it does, the student stops and stands behind that sign. At the end, all the students will be grouped according to their zodiac signs!

To prepare

if birthday falls between March 21 to April 19:
    Your sign is Aries
elif birthday falls between April 20 to May 20:
    Your sign is Taurus

And so on.

    Your sign is Pisces


  1. Have 12 volunteers line up side by side.

  2. Give each volunteer a sign, making sure the leftmost student has the if sign, and the rightmost student has the else sign. It’s best to keep the elif signs in the correct order.

  3. Have each student start at the if sign, to check if his birthday falls within the dates on the sign.

  4. If it does, have that student stand behind the student holding the sign.

  5. Otherwise, have the student step (right) to the next sign, to check if his birthday matches that one.

  6. Let him keep going until he finds a sign that matches his birthday.
