Page 1: Division by 10 and 100 - Basic Principles

The first page introduces fundamental concepts of dividing numbers by 10 and 100, featuring multiple practice examples. The page demonstrates systematic approaches to solving division problems with varying complexity levels.

Definition: Division by 10 involves moving the decimal point one place to the left, while division by 100 requires moving it two places left.

Example: 320 ÷ 10 = 32 demonstrates the basic principle of removing one zero when dividing by 10.

Highlight: When dividing by powers of 10, the number of decimal places to move corresponds to the number of zeros in the divisor.

Vocabulary: Divisor - The number you're dividing by (in this case, 10 or 100)
