I couldn't find a greeting card template on here, so I decided to make and post my own!
This activity is meant to coincide with page 84 of the JHS 1st year New Horizon textbook, where students make and give each other greeting cards, but it can easily be changed to adapt to the needs of pretty much any students in elementary or junior high school.
Side note: To prevent students from receiving unequal amounts of cards, we put students in pairs for this activity and don't just let them give the cards to whoever they want, but again, every class is different!
