Step into the world of mathematical magic! The 1089 trick will leave your students spellbound. It's a playful way to explore subtraction, addition, and number patterns. Get ready for wide-eyed wonder and maths enthusiasm!
Setting the Stage
1
Choose a Number
Ask a student to think of a three-digit number. The first and last digits must be different.
2
Secret Prediction
Write '1089' on a piece of paper. Keep it hidden from the class.
3
Build Anticipation
Tell the class you've predicted the final result. Watch their curiosity grow!
The Mathematical Journey Begins
1
Reverse the Digits
Ask the student to flip their number. For example: 742 becomes 247. It's like magic!
2
Subtraction Time
Subtract the smaller from the larger. 742 - 247 = 495. Maths in action!
3
Flip Again
Reverse the result. 495 transforms into 594. Watch the excitement build!
The Grand Finale
Add It Up
Add the last two numbers. 495 + 594 = 1089. The magic unfolds!
The Big Reveal
Show your prediction. It's 1089! Cue the gasps and applause.
