Students build multi-digit numbers with base-ten blocks and discover that where a digit sits decides how much it is really worth.
Students will be able to…
The digit 3 shows up in 3, 30, and 3,000 — but it means something different each time. What gives a digit its value?
Project this and build any number to the thousands. Change each place and watch the number, the expanded form, and the base-ten blocks update together.
Tap any phase to open the teacher moves and student actions.
3, 30, 3,000 — same digit, different worth.
Teacher builds a number with blocks.
Class drives the Place Value Builder.
Students build and expand numbers.
Point to a digit — what’s it worth?
Aligned to the Common Core State Standards for Mathematics, including the Standards for Mathematical Practice.
Recognize that in a multi-digit number, a digit in one place represents ten times what it represents in the place to its right.
Read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form; compare using > = <.
Use place value understanding to round multi-digit whole numbers to any place.
Look for and make use of structure in the base-ten system.
Preview the three formative checks. Tap “Sample answer” to see what mastery looks like — hide them before you print for students.
Students draw digit cards and place them to build the largest (or smallest) number possible, then justify with place value. A printable game board is in the Math library.
Tap a card to flip it, then rate whether you knew it. Built from this lesson’s vocabulary.
A quick self-check with instant feedback, drawn from this lesson’s key terms.
A print-and-go review sheet with a built-in answer key. Tap “Show answer key” to reveal answers, or print the clean version for students.
