• Squaring means multiplying a number by itself, so 8² = 8 × 8 = 64.
• 64 is called a square number because 64 counters can be arranged in a perfect square of 8 rows with 8 in each row.
• The opposite of squaring is taking the square root, so √64 = 8.
• 8 squared is not 8 × 2. 8 × 2 = 16, but 8² = 64.
• Each square number is the odd numbers added up in order: 64 − 49 = 15, so the gap from 49 to 64 is 15.
