Challenge Solved! You are a Place Value Pro! Not quite! Remember the Ten-for-One rule. Jellybean Progress ... Is it ... ? ... Or ... Amazing work! You built the number 34 with 3 Tens and 4 Ones. Almost there! You have . We need exactly 34 (3 Tens and 4 Ones).
What must we do when we collect ten "ones"?
Exactly! Ten ones always regroup to form one single Ten!
Why is it better to group by ten?
Bundling helps us see large amounts quickly without losing our place.
If you have 9 ones and add 1 more, what happens?
The ones room resets to zero and the tens room clicks up by one!
In the number 87, which digit tells us how many "bundles of ten" we have?
The digit on the left always represents the tens bundles!
In the number 53, what does the 3 represent?
The digit on the right represents the "leftover" single units.
Which number is greater: 4 tens or 2 tens?
More tens always mean a larger total quantity, no matter the ones!
How many Tens make 100?
Exactly! 10 bundles of 10 make 100.
If you have 9 Tens and 9 Ones, what number is next?
99 plus 1 makes 100! The ones bundle into a ten, and the 10 tens bundle into a hundred!
What does a "Big Flat" block represent?
A Big Flat is made of 10 tens, which equals 100!

Counting 87 beans one-by-one is slow and easy to mess up! The Ten-for-One rule says that as soon as you collect ten "ones," you must bundle them into one single "ten." This makes a huge pile look like a few neat groups that are much faster to count.

The Power of the Bundle
Turning messy ones into organized tens.
Every two-digit number lives in a house with two rooms. The room on the right is for leftover "ones," but it can only hold nine guests! When the tenth guest arrives, they all bundle together and move into the "tens" room on the left.

Putting tens and ones in their rooms.
When we collect ten bundles of ten, we bundle them all together to make one giant flat of one hundred! This is how we count all the way to 100.

The Big Hundred
10 Tens make a Hundred!
Did you know that when you get ten bundles of ten, they join together to make a "Big Flat" 100 square? It is all based on groups of ten!
Did you know?
The number 100 is represented by a "Big Flat" block? That is exactly 10 bundles of ten sticks stuck together!
