  • Is that what they call Common Core? I’ve heard the term but didn’t know how it changed the method of teaching math.

    Common core showed multiple ways that were intended to increase the understanding of how math works. This was one of the ways that was presented which wasn’t how they taught it when I was a kid. There were at least two that I remember when my kiddo was doing common core:

    • Double one of the numbers and add or subtract the difference between them (7 is two less than 9, so 9x9 then subtract 2)
    • Take enough from the smaller number to reach 10 and add what is left (9+7 to 10+6)


  • Sigh. Decimals contribute to length. Length.

    Yeah, I’m probably missing what you are saying because I’m replying to what you are writing and the more you explain it the less sense it makes. Like there is nothing that I can think of involving decimals that increases in length. Maybe number of steps, but that is also true the more digits are involved and decimals only add one extra step.


  • Multiplying by 5: mult by 10 divide by 2

    A very similar concept for tipping about 20% is taking 1/10th of the bill by moving the decimal one to the left and doubling that. To make it even easier for me I just round to the nearest $10 amount first.

    Bill: $66.20 -> move left and round up = $7.00 and double to $14.00. The exact 20% amount is a little over $13 but I tend to round up because it is also faster to add whole dollars to the bill.





  • Yup, helping my kiddo with the math portion of Common Core was like seeing professionals finally understanding how easy it is to sort numbers to make stuff easier instead of doing a bunch of rote memorization of tables. Also teaching kids to estimate to know if your math is way off!

    Common Core for math was awesome. That was the only one I had to help with so no idea about the rest.


  • Yes, yes it does. Mental fatigue from working a fucking set schedule that starts earlier than my body wants to every fucking week makes doing anything semi complicated during downtime exhausting.

    When I take off a week and do what I want on my own schedule it is easy to get things I want to do done! Sure, I’m cutting lumber at 2 a.m. and using it two days later after getting sidetracked on something else the next morning, but I’m still doing the five total things I want to do over a reasonable time frame.

    Neurodivergence is a basic part of humanity and always has been. A group with a mixture more easily handles challenges as different people accomplish different things. Obsessing about details is a benefit under the right circumstances. Being impulsive is a benefit for trying new things, like eating new things. Following other people’s lead when it works is great so not everyone is trying new things.

    Heck, not perceiving reality accurately can be a benefit if it means getting a new perspective on things. That is why so many cultures have appreciation for hallucinating in controlled settings.

    Society punishing non-conformity is the underlying problem for sure, where everyone is expected to fit in a narrow scope called neurotypical which in my opinion is not typical at all.
