Definitive Answer: Students will learn to round whole numbers to the nearest 10 or 100 using place value understanding. This skill is crucial for estimation.
Imagine you're trying to quickly guess a number, like how many cookies there are. **Rounding** helps us find a number that's **close enough** and easy to work with! When we **round to the nearest 10**, we find which 'group of ten' (like 10, 20, 30) a number is closest to. Think of a number line! If a number is in the middle or closer to the higher 10, it rounds up. If it's closer to the lower 10, it rounds down. This helps us make **estimations** quickly!
