TEKS Math Standard: 4.2.A

interpret the value of each place-value position as 10 times the position to the right and as one-tenth of the value of the place to its left

What If There Were No Hundreds Place?

What If There Were No Hundreds Place?

Imagine a world with no hundreds place. We’d have to call it ten tens instead. But then, what would we call the thousands place? How would we read 9999? What if we added one more?

Place Value (Beyond Base 10)

Place value is something we cover in elementary school. It seems simple, but I’d wager that very few adults really understand the topic.
