I concur.

It's not ambiguous at all. The statement is perfectly clear. The statement is a contingency, i.e. a statement that is neither valid nor unsatisfiable. (Proof-theoretically: neither p nor not-p is provable. Model-theoretically: some assignment of truth values to p will make it true but not all of them). It would be a far more valuable lesson to teach children that talking about something doesn't will it into existence…

What about "none" instead of zero?

2 to 4 is still early in the development of physical attributes, focus, hand eye coordination, balance and what have you. Zero intentional and structured screen time seems entirely appropriate. Let them develop a physical world and interact with it before encouraging screen addicted couch potato. That will come despite best efforts later...

But why do you believe this? Encouraging physical world interaction before screen interaction (I'm taking away the value judgements) – what makes you think that this is beneficial? What are the benefits? How would changing this change the outcome of the child's life? One theory I have found pieces of and put together is that a primary pillar of mental health is how your life experience as an adult matches your life e…

Expanding on this to postulate: This is why old fairy-tales were so dark and frightening. Scary stories prepare you for a scary world, which it definitely was not so long ago. Many of the feedback systems in your brain are trained in childhood and become much more fixed as an adult. Homeostasis trained on the "child" dataset goes all out of order on the "adult" dataset when the two are too different.

Lavish your child with praise and attention, everything they could want and making sure everyone is successful at everything and never "fails" ... come to the real world as an adult and reality isn't as nice, the world isn't actually like what you grew up in and your feedback systems simply aren't equipped or designed to handle the situation life puts you in.

Controversial opinion, but I don't think kids ages 2 to 4 should be having screen time, let alone an activity that is better presented with real objects.

Personally I think screen time is just another tool in the learning box, along with books, puzzles, toys, outside play, helping with chores etc etc. I don't really get the consternation over a child playing a counting game with an app over one with physical items (though play physical items is very necessary).

And apps take up no space while also easily being updated to be more challenging as the child's capabilities grow.

I don't think that's controversial at all. I'm not aware of any kid of age It's usually the first/second issue discussed when sending kids to friends homes.

Average screen time for children 2-8 is >3hrs a day so your world is atypical. http://cdn.cnn.com/cnn/2017/images/11/07/csm_zerotoeight_ful... page21

So, I am older than 4 and have a PhD in a logic-related field. BUT. I have to admit that I had trouble answering some of those questions. For example: "How many blue cats are not bouncing" when there are no blue cats on the screen. The game seems to assume that the right answer is zero, but I'm not sure I concur. There is a presupposition there about blue cats being in existence and if there are none on screen, the r…

When you treat the screen as just a sample of all the cats, and you assume that every question is really asking "out of the ones that are on the screen" then 0 makes more sense. The language used by the quiz treats the cats as real, so it's like you're sampling and then evaluating the sample.

If I apply your logic to that, then we never know any quantity of any type of cat in any question, because there are more off-screen.

I was not prepared for the text-to-speech blaring out at maximum volume without warning. I was further not prepared for "mute site" in chrome having no effect. Does anyone have any advice for blocking this behaviour on a global level?

Just a warning for future explorers

Doesn't this apply to all of the questions? After all, there could be more cats than are displayed.

heh :) only read this after trying while my notebook was muted. Quickly closed the tab before I accidentally unmute and wake the lil one

Will be trying the counting part with kid next morning.

I assume its random() based, did get a lot of 3 cats, specially in a row. Never 0 cats or more than 5. I would remove the answer buttons for 6 to 0, or a button to hide those maybe?

Nice website. I like it. Please don't use it with your kids (of 2 to 4!!). There are more than enough actual objects scuttered in your house.

agreed.

this tool seems to optimize practicing logic more than enjoying logic.

i think kids will find greater success in life with logic if they're taught to enjoy it before they're taught to master it.

why do i think this?

my dad wrote a "computer game" in 4th Dimension in the late 80s that was just randomized arithmetic problems. i had to get a certain score before i could play outside etc. i got really good at answering his program's stupid questions. i also learned to resent him for it and have negative associations w arithmetic to this day.

i also quickly lost my "skills" and am bad at arithmetic now.

it was a nice idea but please don't repeat his mistake.
