A special mark is like a special sign that can help you remember something important or special. Just like when you draw a smiley face at the end of your homework to remember to smile, a special mark can help you remember important things too. It can be a star or a heart or any other symbol that you like. For example, you could put a special mark next to a really important date on your calendar, like your birthday or a special holiday, so that you don't forget the date. Special marks are a fun and useful way to help you remember important things!
