We‘ve been working on estimating in class and I must be doing something right because our school librarian complimented my kiddos on it. She has a guessing contest in the library each book fair and the winner gets the estimated goods (candy) as well as a gift card to the book fair. She said my class rocked it out with strategies this year. Love that!
I wanted to share a little secret with you. I can’t take credit for it though… this one is all Laureen’s from Teach With Laughter! I am loving her her Estimating Throughout the Year math packet.
I gather whatever I need for the center and then leave it out for a couple days so students can investigate before making their guess.

They get really into it! In addition to looking at the known number model, they’ve learned to count how many you can see in one column or across the bottom and then multiply that. As you can see, it’s a hands-on process. I never share pictures of my kids on this blog, but I wanted you to see it. They are working those strategies!
We don’t just estimate in jars though. I also used the newspaper one. I can’t leave this one out because students could easily count the individual words, so I just give them a quick drive-by look. They compare the large section to the smaller known section on the right before making their guess.
This is just a sneak preview. There are 17 stations in the packet. We haven’t used them all yet, but next year I’m going to space them out throughout the entire year so we get to them all. They are cute, cute, cute!
If you want to win a FREE copy of this estimation pack, leave a comment below with your guess of how many gumballs were in my jar. The closest guess wins it and I’ll pull a winner Friday. For an up-close preview of other fun teaching products, you can check out the links below.

Lucky 113!
This looks like such a fun activity…and my students could really use more practice! We estimated something recently and the guesses went from 40 to 2000something. Seriously. (There were 200ish.)

Very cool idea! I've done the gumball/candy guessing jar before as well as and the students love it. I've never thought of a newspaper article. That is clever!
My guess is 135.

We had several close guesses, but the winner is Charlene! She guessed 147 and the jar actually has 148. Check your email because your freebie is on the way!
Wow! Thanks Christi! I was so surprised to open my email and find this prize. I had to go back and check out the post to see what others had guessed. I can see that this will be a valuable resource in my classroom. Thank you for the opportunity to try it out.
