What is a compound word in simple terms?

Two whole words glued into one: snow + man = snowman. If you can split a word into two smaller words that each stand alone, it's a compound. Kids love the gluing; the skill is checking that both halves are real.

Is every long word a compound?

No, and that's the useful test. Jumping splits into jump and -ing, but -ing isn't a word, so it's not a compound. Playground splits into play and ground, both real words, so it is. The split test settles every case.

How to teach this

Make it arithmetic on the board: sun + flower = sunflower. Then reverse it: hand your student a compound and have them split it with a karate chop between the words. The chop game reveals which words are truly compounds and which just look long.

Watch for: Both halves must be real words on their own: sunflower counts, but jumping is just a word with an ending. The new meaning can drift from its parts: a ladybug isn't a lady, and a butterfly isn't butter.
