Here is a hands on center.
0 - 20 counting the numbers. One to one correspondence.
Print on card stock. Laminate and put in a baggies. Instant center.
Included are the acorns for the center. The larger ones are for 1-10 and the smaller are for 11-20.
There is enough for the whole center.
You can print on paper and have the students cut and glue them in the correct places in the ten frames to use for an assessment.
See sample pic of the acorns printed on brown paper. This will save ink.
Let me know if you have needs for other games or activities.
Thank you for your time.
