• Squaring means multiplying a number by itself, so 5² = 5 × 5 = 25.
• 25 is called a square number because 25 counters can be arranged in a perfect square of 5 rows with 5 in each row.
• The opposite of squaring is taking the square root, so √25 = 5.
• 5 squared is not 5 × 2. 5 × 2 = 10, but 5² = 25.
• Each square number is the odd numbers added up in order: 25 − 16 = 9, so the gap from 16 to 25 is 9.
