Create a funny, engaging animated math teaching video for a 7-year-old student learning two-step word problems involving addition and subtraction of two-digit numbers.
**Story:** A silly monkey has 24 bananas. He steals 18 more bananas from his neighbour and then eats 15 bananas because he is extremely hungry.
**Visual style:** Colorful, high-quality 3D cartoon animation for children, expressive characters, funny facial expressions, exaggerated reactions, playful sound effects and cheerful background music.
**Voice-over:** Use a warm, energetic, friendly English-speaking teacher's voice. Speak slowly and clearly, suitable for a young child. Include funny character dialogue.
**Scene 1 — Introduce the problem:** Show the monkey with 24 bananas. The narrator tells the story. Animate the monkey stealing 18 more bananas and looking very proud.
**Scene 2 — Ask the student:** Pause the action and ask, “The monkey had 24 bananas and got 18 more. Does his number increase or decrease? Should we add or subtract?” Leave 4 seconds of silence for the student to answer.
**Scene 3 — First calculation:** Animate the bananas joining into one pile. Display large, clear text: 24 + 18 = 42. Explain that adding is appropriate because the monkey received more bananas.
**Scene 4 — Second step:** Show the monkey eating 15 bananas. Ask, “Now the monkey ate 15 bananas. Does he have more or fewer bananas? What should we do?” Leave 4 seconds for the student to answer.
**Scene 5 — Solution:** Display 42 − 15 = 27. Animate 15 bananas disappearing from the pile. Explain that we subtract because the monkey ate some bananas.
**Scene 6 — Funny ending:** The monkey looks shocked and says, “Only 27 bananas? I need a bigger shopping basket!” The narrator confirms, “That's right! He has 27 bananas left!”
**Teaching requirements:**
