# 100 Subitizing Slides & 10 Challenge Patterns

With a click, a pattern of dots appears on your screen. Instantly your students tell how many. They don’t count the dots. Instead they simply know the total at a glance.

Subitizing – when a person looks at a small set of objects and instantly detects the total without counting. It’s a powerful process and a truly remarkable one.

I have a new resource for you. 100 Subitizing Slides & 10 Challenge Patterns.

There are 10 sets, and each set includes 10 subitizing slides and 1 challenge pattern. In between each slide, I’ve placed a blank slide. As you click through the slides the effect will be that the slides are appearing and disappearing – at the rate that you choose. The blank slide will also allow you to toggle back and forth to an image or simply move forward to the next image.

Then, after 10 quick subitizing experiences, you’ll see one challenge image which will be duplicated several times on the screen.

Download the sets, try them out in your classroom, and let me know how it goes!

How would you recommend using the subitizing slides on Zoom when the students can’t all be unmuted to say the number otherwise there’s a terrible echo.

Hi, Hannah. Great question. The students can still all subitize when they see the image. Of course, after that, they won’t all be able to tell you the number aloud due to the microphones. I know there are a lot of other strategies including jotting down the number or showing it to you in another way. Another option would be to use fewer of the subitizing slides (perhaps 10 instead of 5) before moving into the challenge pattern where you would spend more time.

Hi,

First of all THANK YOU!!!!!!!!!! Your slides are so amazing! I teach grade 5 and stumbled across your site this year, and was so happy. I started with Esti-mysteries and my class loves it.

My question is….. With all of your resources, do you suggest a schedule at all? As in, which things to start with? Is there any scaffolding at all? Or do they all go hand in hand.

Thank you so much. I am just trying to make some schedule to follow. I started with Mystery Monday… with esti mysteries. I would like to work in the multiplication course as well, my students are quite low, and even though are in grade 5, they can really benefit from it.

THANK OU

Hi, Kristen. You are certainly welcome, and I appreciate your kind words. I recommend establishing a routine that works for you. For example, your Mystery Monday sounds like a great routine. I know that some are doing some on Wednesdays or Fridays. You could also blend the approaches and have a Mystery Monday and a Clipboard on Wednesday and a Splat on Friday or something like that. Really, the resources are available to use in whatever way work best for you so feel free to try some different approaches. In general, the estimation clipboards are a little shorter – in terms of how long they take – than the Esti-Mysteries so if you have a day with more limited time then I would recommend a clipboard on those days. As far as the scaffolding I’ve tried to build that in to all the resources so you’ll have that available. Simply present the resources on the days that work best for you, ask rich questions, and let your students amaze you with their ideas.

Thank you so much! Your resources are amazing!! And I’m so glad to find your website!!

I’m so happy you found it, and I’m grateful for this message!

This resource is excellent for remote learning in Kindergarten! Merci! Thanks so much for sharing.

So generous to share…thanks

My pleasure, Penny!

Wow! You are great!!! Thank you for the free slides. The resources are very fun for my Kinder students. THANK YOU!!!!

Thank you so much for your amazing ideas and creativity to make maths meaningful, engaging, challenging and fun for my students. My students have loved SPLAT and esti mystery. I now have younger ones this year so subitizing will also be a wonderful resource.

My pleasure, Jillian! I really appreciate the comment!

Thank you for all the wonderful work you share! I really appreciate it and look forward to seeing your posts.

Steve I just wanted to say that I think you’re an amazing person. I’ve followed you for several years and the things you have done to enrich teachers understanding of how math should be taught is inspirational. Thank you for all you have done and continue to do.

Steve,

Thank you for sharing this amazing math talk. I am teaching Kindergarten and now it’s Distance Learning. I am going to integrate your number pattern subitizing with my students via Zoom. It will be a meaningful math discussion for remote learning.

Hi Steve, Thank you so much for this usable material. I really appreciate it. As a kindergarten teacher, this is great. An interactive lesson, discussion and involved children. What more could one ask for? Thanks

My pleasure, Stephen. I’ll keep them coming!

these are amazing! I’m excited to use them! Thank you for sharing

This is an amazing site! Thank you for sharing these wonderful resources. Subitizing is an essential skill for our students. These slides will make it fun for my students and simple for me!

Thank you these are awesome

Excellent goods from you, man. I’ve understand your stuff previous to and you are just

too wonderful. I really like what you have acquired here, certainly like what you are

This is actually a terrific website.

I can’t wait to share these with my primary teachers. Thanks for making them available!

I figured it out! Thank you SO MUCH for sharing your resources! My students love Splat! The subitizing slides are going to make my life so much easier. I truly appreciate these resources.

Steve Thank you. The links are working now

The links are working! Thanks Steve

The best part about these is that the kids love them! They are engaged and excited about discussing the math contained on them!! Thank you so much!!

Thank you!

What another amazing resource! Thank you so much for sharing! I shared with all K-2 teachers at my school!

Thanks, Roslyn!

Thank you so much ! Your resources are Amazing

I was able to download all ten sets! Thank you so much for all you do. It is so generous of you to share all your work! My students and I LOVE the SPLAT!

Steve, the sets are not available for downloading from the email or your webpage. Dan

Hi, Dan. Can you try it now and let me know if the links are live?

Hi Steve. The sets are not linked to a download from this site or the side sites.

I can’t download. Could you please check the link. Thank you

I think it’s working now, but please let me know. Thanks!

Hi Steve,

I have used and LOVED your SPLAT slides. Where can I purchase the subitizing slides?

Thanks!

Tammy

Hi, Tammy. They are all free. The links should be active now so you can download them. Thanks for the kind words!

Thanks for everything you share! I love your resources. I would love to try out your subsidizing activities, but cannot find a way to download the slides. I don’t see a link in the email or on your blog. Can you advise?

Thanks!

Hi, Victoria. Go ahead and try it again. I think the links are all updated now. Thanks!

I’m interested in your subitizing slides, but the links are not active.

Hi, Angela. I believe they are all ready to go now, but would love some feedback on if they are set and working. Thanks!

Hey, your links are working now. Thank you so much!
