Appreciation has quite a few meanings but we are going to take it to mean when you tell someone that you value them or what they have done, that you care about them.
Appreciating someone means that you don't just take them for granted. You stop and take the time to say:
"Well done",
"Thank you",
"I really appreciate that".
Showing your appreciation costs nothing and can be fun to do. If you show other people appreciation, hopefully they will do the same for you.
Some ways you can show appreciation
Say thank you when someone does something for you
Clap after you have seen a good performance
Cheer on your team or people taking part in a race

Celebrate people's achievements with certificates, reports and Records of Achievement

Give someone a small, maybe homemade, gift to day thank you
