The problem

Seventeen means ten and seven more

Counting to 20 is easy to recite and hard to understand. Children need to see that 17 is a quantity, not just a word.

Counting from one every time

To show 17, a child counts out one at a time. They have not yet used a ten to help.

Losing track in a big group

Past 10, scattered objects get recounted or skipped. Touching and moving each one fixes it.

Numeral does not match amount

A child can write 15 but may not know that it is more than 12. The number needs to connect to a quantity.

Children count groups up to 20 and match each to its numeral. Seeing the same amounts in different layouts builds a feel for how big each number is.

Questions

Before you buy.

Is this just counting?

It is counting with understanding: matching amount to numeral. Writing numbers is covered in other sets.

How is it different from Counting to 20?

This set builds the feel for size to 20; Counting to 20 focuses on counting accurately.

How do I get the file?

The download link appears right after checkout and lands in your inbox at the same time. One PDF with 13 pages. No account needed.

Can I print it more than once?

Yes. One teacher or one household can print unlimited copies for their own students, this year and next.

Will it print in color?

The pages are designed to print in black and white, so they print clean on any home or school printer and do not eat a cartridge.
