Equivalent Number Representations
Learners bundle straws into ones, tens, hundreds, and thousands for a class store. Today they use the model to explain counting, representation, cardinality & ordinality in their own words.
Equivalent Number Representations illustration
Learners bundle straws into ones, tens, hundreds, and thousands for a class store.
What number has 3 hundreds, 5 tens, and 2 ones?
- Build the large groups first, then the tens, then the ones.
- Read each place from left to right to get 352.

Equivalent Number Representations rescue model
A class shop bundles straws into place value groups before recording the number in digits.
Draw place value columns and keep each bundle type in its own column.
Bundle straws into tens and hundreds before writing any digit.
One bundle can stand for 10, 100, or 1,000 depending on its column.
Sketch the bundles under hundreds, tens, and ones labels.
The picture keeps each place value in the correct column.
Write one digit for each place value column.
3 hundreds, 5 tens, and 2 ones becomes 352.
The learner swaps tens and ones when writing the number.
Ask the learner to rebuild the model slowly and say what each part means.
Point to each column from left to right before writing the digit for that column.
The learner gives an answer without connecting it to the objects.
Cover the written answer and ask the learner to point to the matching part of the model.
Return to the concrete objects, then redraw the same idea before writing the answer again.
Build one number with bundles, then cover the bundles and read the digits in order.
