Math Workbox: Estimation

I'm creating a series of 3x5" math task cards. I print them on cardstock and organize them in a recipe holder to rotate through our Math Workbox.

Today, I begin with cards on Estimation, using Bruce Goldstone's awesome books, Great Estimations and Greater Estimations. (Please see my book reviews and read an email from the author.)

I made 3 task cards that I will rotate through a Math Box along with Goldstone's books. In one activity, for example, the Math Box will include a baggie of 1/2 cup of popcorn. My student will count out 10 kernels, then 100 kernels, and use that information to estimate the total number of kernels, modeled after the visuals in Goldstone's books. Another task card includes a link to the author's website where students may estimate using the "Estimatron."


The cards are available in pdf format as a free download. Grab your own and print them on cardstock. Please enjoy the activity and leave me a comment to let me know what you think!

P.S. I'm sorry the tea towel (right) is wrinkled. I don't take time to iron. I take time to create math activities! ;)


I invite you to link to a Workbox post on math. Please link to posts that emphasize Living Books, games, and hands-on activities as opposed to worksheets and drills.

    Thanks for the printable. I will link up my post on Monday. I tried to do some estimation work with my almost 4 year old, but she finds it very boring.

    I've tried several times to ad a link to the series with the Thumbnails but it has been impossible snif.

    Good Idea,
    It's a post from a few months ago, but I thought it would be a nice one to share in your series.
    It's lego and Maths.

    I am about to implement the use of math boxes in my classroom. Until I came to this sight, I was stumped as to what I would put out that would be both engaging and active. Thanks!!!
