Algebra 1 and pre-algebra worksheets are something that all would love to have been able to dominate in high school. Sometimes they do not dominate it there and that's when it could be a bit difficult.

If you are a parent who wonders why you are not seeing Easter educational activities that you return home with your child, you are not alone.

When school systems go to spring, particularly after a long snowy winter, they tend to ignore Easter and enough stinks to spring topics. Teachers are feeling the crisis and will affirm that they do not have time to create Easter thematic activities.

Children these days are expected to do more at school at an earlier age than ever. Years ago, students were learning to read and write at first grade. Nowadays, children are learning to read and write in kindergarten.

With the increase in the demands of the school curriculum, it is not surprising that the subject of "handwriting" or "penmanship" has fallen by the way.

1st grade mathematics work sheets and my mother's mathematics teaching style. Mathematics will not be so terrible, since it seems that parents are interested in preparing their little ones for mathematics before school age.

I grew up without understanding how people talk about mathematics as difficult as they do, it was my best topic at school.

These days, a lot of teachers is expected.

They have larger class sizes, the number of subjects is increasing, the curriculum for these subjects is increasing, and they have to deal with multi-level classes where students are at different levels of knowledge and capacity.

You can always keep track of things like your money and solve certain real-life problems by putting things in an equation and then resolving them.

Knowing the algebra is something that people should do to achieve it to find a good job and for success in college, as well as life. Learn mathematics such as algebra and arithmetic now because as time passes, it becomes more difficult to learn things.

⬇️⬇️⬇️ The "Math" of Fear

As it is Thursday, I have a post for you today in anticipation of Gov. DeWine's new Maps of Fear which he has tried to phase in. I have previously discussed both the new red and blue maps and their issues -

- but today I hope to illustrate even more clearly what level of manipulation is going on, particularly with the new blue 'ICU Utilization' map.

Attached I have two images.

The first is a hyper-simplistic (and unrealistic) but illustrative example of the calculations that the new blue map goes through to arrive at its numbers.

Instead of telling us the percent of beds occupied by COVID+ (not necessarily ill *with* COVID, but testing positive) - the governor and ODH only calculates the percentage of COVID+ out of just the *used* beds.

In the first image, I have an example of a 100 bed ICU with just two patients - one COVID positive (red) and one COVID negative (green). The other 98 beds are empty and able to accept new patients.

IS HISTORY ALL TRUE SERIES: when even the #Calendar isn’t❓

THE REAL ACTUAL SOLAR CALENDAR:
*Based on the noble science of #Astronomy; the sister science to #Geometry, #Mathematics and the “almost” lost numerical science mysteries. Which was mastered in

“ancient” times, but is close to forgotten, in these “modern” days. Go figure❗️😄☦️

Navigation of the oceans was man’s first real great step of personal evolution, here on earth. The earliest of discovered sciences; #astronomy; allowed men to navigate through

routes to known territories; or to discover new ones, by the endlessly reliable positions of the stars and constellations, in the night sky. Hence; much diligent study, over who knows how many epochs, and great civilizations; was an esteemed scholarly pursuit. And led to a vast

understanding of the mechanics of our solar system, as well as the natural cycles of our planet, that even we; in this so-called Information Age “high civilization, don’t often know even exists any longer. A decay of common knowledge, in our “modern” educations, actually.

#Calendars have come and gone In the last few thousand years; motivated apparently by the politics of the day, or personal whim even, by the rulers of the moment; which somehow stuck, from there, and has hardly ever been questioned again.

Saharon Shelah and number 4, a thread.

Shelah is an incredibly prolific mathematician working mostly in mathematical logic who has (co-)authored around 1500 papers so far. His other superpower is the ability to discover number 4 where it has absolutely no reason to be. 1/32

Example 1. "There are just 4 second order quantifiers".
In first-order logic, one is allowed to form statements about structures, such as graphs, groups, fields,
etc., with only quantification over elements allowed. 2/32

So you can say "exists x, ..." or "for all x, ..." with x ranging over the elements of the structure M, but you can't say "for all subsets of M, ..." or "for all binary relations on M, ...", etc. Allowing such
quantifiers puts us in the context of _second order logic_. 3/32

It was well-known in logic and computer science that one can express more complicated properties by quantifying over binary relations on M rather than just over the unary ones. But can we say even more quantifying over ternary relations? 4/32

And how does this compare to quantifying over functions, bijections, or any other infinitely many possible types of relations on M one can think of? In his 1973 paper Shelah proved that there are exactly 4 (four) possible types of second order quantifiers. 5/32
