Understanding Numbers

Numbers are everywhere! In 2nd grade, you'll get really good at reading, writing, and working with numbers up to 1,000. You'll learn to see how each digit in a number has its own place and value.

• The ones place is for single units.
• The tens place is for groups of ten.
• The hundreds place is for groups of one hundred.

Breaking Down Numbers

You can break down numbers like this:
\( 372 = 3 \times 100 + 7 \times 10 + 2 \times 1 \)

Why Place Value Matters

Place value helps us quickly understand how big or small a number is, and helps us add and subtract easily.

Fun Activities

• Use base-ten blocks to build numbers.
• Try skip counting by 10s and 100s.

Real-World Use

Place value is used when counting money, keeping score in games, or reading large numbers on signs.
