  1. I can’t wait to use Splat! in the classroom. I will definitely be sharing this with our teachers too! Thanks so much for sharing – I appreciate your hard work!

  2. Steve, another enthusiastic user report. My 4 year old and I played/talked through the first set and she really enjoyed it. I might follow Simon Gregg’s example and make some physical manipulatives to recreate the activity and also let her set up challenges to give to the rest of the family.

  3. Hi Steve, I love this idea! It is crying out for a Javascript application that can live on the web for people who don’t use PowerPoint. I’ll see how long I can put it off before I am compelled to start adapting it… Best regards, Scott

  4. Sorry, but this was just too long to put in a Twitter post. I have a Montessori class of 4th and 5th graders, and we began on your first 2 Splat sets. I could see their speed grow as they were able to subitize with confidence.

    But then, we began Set 3 today (only one color splat) and they got it instantly, with almost as much speed! Amazing! When I showed them the algebraic equations they were solving, they were impressed with themselves, and now want to generate them each time themselves.

    I can’t tell you how much I think of your ability to develop these and also share them so freely with the world! This is a game-changer for sure.

  5. HI! I LOVE ALL OF YOUR WORK! Thank so for sharing. Can you please explain to me in your video at minute 5:22 where it ends with 2(S) + 3 = 10… is that a non examples b/c I think it should be 2(S) + 2 = 10… apologize if I’ve missed something – I just want to be sure when I pass this along that I can explain that part!

    1. Hi, Laura. Thank you so much for the comment and the question. What you see at the 5:22 mark is purely an error. It should say 11 rather than 10. I didn’t intend it to be a non-example. It was actually a typo in the number box in the top corner. I will try to correct it down the road. That is such a great catch on your part. When you do share this out, let everyone know that the lessons should all be correct. Thank you again, for commenting, and nice catch!

    1. Thanks, Graham! I stumbled across some additional Splat! strategies very recently that lit an enormously powerful discourse wildfire in the classroom. It all started with something like, “Mr. Wyborney, it’s not possible to put 7 dots under 4 splats… Is it?”

  6. There appeared to be an error in your video. At the with 1.21 left. You have a ten in the top right corner. Three dots in the middle, and four dots under the two splats. It’s your 2s + 3 = 10 example. I counted 11 dots.

    I do love this for number Sense. Thanks for sharing.

    1. Great catch, Josh! If I had an opportunity to change it, I would quickly update it. In the meantime, it has given me an idea. Thank you for pointing it out – and thank you for watching the video. I hope you will enjoy the Splat! series!

  7. Hi Steve,

    This is a cool resource. I have another question re: Splats about the yellow question boxes. I’ve clicked on them but I don’t think I’m doing it right because nothing happens. I have to rearrange them (as I said, I’m probably missing something!) to read them. Or if anyone else can help, that’d be great.

    Thanks,
    Leslie

  8. I had the opportunity to share this blog with many teachers today. The excitement in the room could be FELT! Thank you! This is an amazing resource to promote number sense!

    1. Thank you for sharing this experience with me. I’m excited to hear this. I’ll be making more soon. I really appreciate your sharing this with other educators as well!

  9. This looks so awesome! We are incorporating Number Talks and this is such a cool, new addition to that program! Thank you so much!

    1. Travis, I see exactly what you mean. Thank you for catching this for me. I originally you thought it was on one of the lesson slides, then realized you pointed me to exactly where it was on the video itself. I really appreciate it. I may not have a chance to record the video again until after I finish the lessons. There is something about your comment that is featuring a really good, completely unexpected opportunity. I haven’t completely pinned it down yet, but the combination of a mistake and a video could lead to some really good math lesson opportunities. Thanks, again!
