This estimation and data jar is perfect for grades 2-6. Use this form (and customize it to fit your needs) to place on a jar. Students can take the jar home, fill it with inexpensive goods, and bring it back. Then in class, students will guess how many items are in the jar. At the end of the week, the student who guesses closest should receive a reward. I give out candy, but you can do whatever you want.
With younger grades, the estimation jar works wonders helping students learn to estimate!
When you are working with older students, the jar changes to the estimation and data jar. After each student estimates, compile all of the estimates. Then, find the mean, median, mode, and range of the data. This is a fun, educational math activity that promotes estimation and data skills.

Was this just one sheet?

I purchased the estimation and data jar but did not receive the activities that go with it. Did I pay $1.50 for just the parent letter? If so, I think I deserve a refund because this parent letter is what you show as a preview.

i had originally wrote a longer message, however, when I went to Edit the message, I was unaware that it would delete what i had originally responded with. So I apologize if you received many emails in regards to this answer.
I looked up the refund policy, and it reads as follows: "What is your refund policy? Premium Seller Subscriptions are refundable within 30 days of payment. Refunds on product purchases are made on a case by case basis and are only provided when the product was not as advertised by the seller. If this is the case for you, Contact Us and write a detailed message explaining the situation."
I do believe I was clear with my description of the estimation jar. Please go back and reread the description if need be. However, I do not want to leave you upset about your purchases. Please let me know if there is another item or two that you would like of mine, and I can email them to you for free if the refund does not work out.
Please let me know if there is anything I can do.
Thank you.
