The problem
Is 12 bigger than 21?
Teen numbers are a place where kindergartners and first graders slip. The digits are small but the order matters.
Flipped digits
12 and 21 use the same digits, and children easily pick the wrong one. The first digit tells how many tens.
The symbol points the wrong way
Even when children know which is bigger, the open end of the symbol gets drawn facing the smaller number.
Teens versus single digits
20 compared with 8 or 15 compared with 4 sounds easy, but only if a child knows teen numbers are bigger than all single digits.
Each question asks for >, < or = with numbers up to 20. The teens are included, so children learn that a ten plus some ones is bigger than any ones alone.
What’s inside
30 questions, one per slide.
Students type straight into the box — no printing, no cutting.

Questions
Before you buy.
Is this the same as Comparing Numbers to 10?
No. This one adds the teens and 20, where the digit order matters.
What if my child can only compare to 10?
Start with the to-10 set, then come here when teens feel familiar.
How do I get the file?

Can I share it with my class?
Yes — one teacher can use it with their own students, this year and next. Sharing the file with other teachers needs a separate license.
