I’m posting a brand new resource – every single school day – for the rest of the year.  They are all free, and you can download as many of them as you like right here from my blog.  This is for everyone.  Each day for the rest of the rest of the school year, there will be a link to a brand new never-before-seen resource.  Many of them are new Esti-Mysteries.  This is part 2 of the continuing New Esti-Mysteries and Number Sense Resources Every Day for the Rest of the School Year.  Part 1 (November 1 – January 8) can be found here.


Here’s why:  This is a challenging year, and this series is my way of providing encouragement, promoting math joy, and sharing a new resource every single school day this year.  I’m creating something new every day, posting it on my blog each evening, and you can download each and every resource here.


I’m surprised to be writing part 2.  That’s because my original plan was to put everything on a single post – this one – but the list of resources, which I began posting on November 1, was becoming pretty long – and we all needed to scroll down more and more to find the new resource each day.  Instead of making the list even longer, I decided to add this next post, which is Part 2, so we could find new resources easily on the top.


If you have been following this series, nothing else has changed.  In this blog series you’ll find a link to a new, free resource every single day.  I’m sticking with you to the end of the school year, and I have a gift for you each and every day through May 1.



The original post is here.  So you can easily find all of the resources from November 1, 2020 through the beginning of January here.


The schedule continues as follows:


Every Monday – Brand New Estimation Clipboard (all grade levels)

Every Tuesday – Brand New Esti-Mystery for Kindergarten AND a brand New Esti-Mystery for Grades 1-2

Every Wednesday – Brand New Esti-Mystery for Grades 1-3

Every Thursday – Brand New Esti-Mystery for Grades 3-8

Every Friday – Brand New Mystery Number Sense Resource*  (all grade levels)


*The Friday Mystery Number Sense Resource is a surprise.

If you haven’t used the Estimation Clipboard, I recommend watching this short video on my YouTube channel beginning at 0:42.  Although it features a different estimation clipboard, the directions are the same.  You will quickly see how use any Estimation Clipboard.


By the way – when using Estimation Clipboards, be prepared for a LOT of cheering in your classroom!

    Why not list topics in reverse chronological order so new stuff is always on top? I’ve just started using some of your activities, which have gone well—thanks.

      Hi, Steve. I originally considered reverse chronological because I knew it would work for every new day – for everyone that is currently viewing them. However, I realized that for anyone entering into the journey in the future, they would need to scroll way down to find the start of the journey and it might confuse them. So, I created the new post to bring the newest ones back up to the top while keeping the sequence in order. I wouldn’t be surprised if I need to add a 3rd post after spring break. Thanks for asking. That’s something I wrestled with for quite a while.
