🧩 Representing Numbers in Multiple Ways

Numbers can be shown in many different ways! In this quiz, you'll explore how to represent the same number using base-ten blocks, drawings with bundles and dots, place value charts, and expanded form. You'll learn to recognize when different representations are equal and move flexibly between them. **What you'll learn:** - Identify equivalent representations of numbers up to 200 - Convert between base-ten blocks, drawings, and expanded form - Use place value charts to organize tens and ones - Recognize that $23 = 2 \text{ tens} + 3 \text{ ones} = 20 + 3$
