Math riddles often involve wordplay and require students to interpret the clues provided. They encourage reading comprehension alongside math skills.
Example Riddle:
“I am an odd number. Take away a letter, and I become even. What number am I?”
Answer: Seven (remove the “s” to get “even”).
2. Logic Puzzles
Logic puzzles require students to use reasoning to solve problems. These puzzles often involve patterns, sequences, or relationships between numbers.
Example Logic Puzzle:
