Fractional Exponents!

I subbed for Wes yesterday. They were learning about fractional exponents. Words like these are terrifying to me, not to mention that there were square roots involved. The first class was way smart and I just put up the notes and they did the assignment, but by the end of the day, I had to figure out how to do the entire thing and be helpful. I would say, "When Mr. Hall comes back tomorrow, he will give you a mathematical version of this lesson."
Now let's think about it. How many times in a week do you deal with fractional exponents? How many times in a week do you deal with exponents? I just don't like them and I have a huge prejudice against anything with the radical sign. I would rather deal with an untamed lion than one of those. So when the kids ask, When are we going to use this in life? it is difficult to come up with an answer.

Well at least you were able to figure out how to do it and be helpful. I could no way figure out how to do them! Math is not my strong subject...after my last college course of math I vowed to never take a math class again.
And no, I don't use fractional exponents in my daily life.

Please say to told the kid's you are never going to use this I don't know why Mr. Hall is even teaching this.

The only people I know that use fractional exponents are teachers that torture students with them.

Harvest Blessings

Image
I love the end of Summer with its beautiful harvests.  The smell of soup that fills the kitchen. I spent most of yesterday making tomato soup for grilled cheese and tomato soup dinners this Winter.  I'm so grateful that my neighbor gifted me the tomatoes and fresh onions were available at the Farmers Market. This simple recipe is 100% nutrious and delicious.  I freeze the soup in 3 cup portions. It's what Wes uses to cook dinner once a week. I did think that it was a lot of work so that Wes could think he cooked dinner, more than once yesterday.  Love living in Idaho.... Harvest Blessings.... Good day...

The Summer of $50 Picnic

I love a picnic, but this year has been pricey. Some of these picnic were for two and others for more. They were all the best. Eaten in the mountains or by the sea, they were all enjoyable.  Wood River picnic area. Johnson Lake in Canada  Crab sandwiches in Bodega in California.... Challis Idaho  Redfish Lake Idaho. What a beautiful way to spend the Summer. Sandwiches and cookies, blue skies and good company.  Not ready for Fall.... Happy Summer Days.....

Walks, Lake Day and I've had Enough

Image
I love my morning walks this time of year. I tend to focus on the beauty  Because we all know that when Winter comes, I'll be whining. Had a beautiful day at Redfish .. Picnic and lake time.  And to finish up this post, it's my anniversary. To be honest, this has been a really hard year. I am working very hard on not correcting the things that Wes says. He is often confused and his problem solving skills are declining.  My other problem comes when we are around people in the stake and he's always walking up to people (who are apparently Bishops) and saying, ' Hello Bishop'. I don't even have words to describe how weird I think this is.   Sometimes I feel like he has joined a club that I want no part of.  If you have any words of wisdom....I need them.  I have been thinking about my mom and these were her words of wisdom...Men are weird and they get weirder w...
