As requested...More Math Stumpers

These math stumpers come from Marcy Cook's Primary Starters and Stumpers. The #s I write next to the stumpers are for me to remember which ones I have given to you. Enjoy trying to figure out the answers to these problems. Don't forget to comment.

Math Stumper #22
How many nines are there between 1 and 110?


Math Stumper #23
1+11+111=1111
Move one of these lines to make a true equation.

Math Stumper #25

#38 of Primary Starters and Stumpers by Marcy Cook

What 5 different numbers have a sum less than 11?



Science:

Paper Magic(Pop Bottle Science)

Can paper stay dry in water?
Materials:
wadded-up paper, an empty 2 liter bootle with the top portion cut off, a bucket or large bowl filled halfway with water
What do you to do...
1. Stuff the paper into the bottom of your bottle. Check to be sure the paper stays in the bottom and won't fall out when you turn the bottle upside down.
2. Turn your bottle upside down, and push it straight down into the bucket of water. (Be sure the bottle is vertical, and don't tilt the bottle!)
3. Lift your bottle out of the water. (Again, be sure not to tilt the bottle.)
4. Remove the dry paper.

Let me know if it worked and why you think it worked.
I can't wait to hear from you.

GoogleDocs is a great way to easily type up information and send it out either through email or sharing it with the public. I can open it from anyone's computer without having to email it first. I went ahead and typed up a spread sheet for averaging some grades, which I obviously would not share with the public but would keep on my documents on my gmail account. I also started a letter to mail out to my students, but again this won't be for the public. However, with our SBISD laptops, I don't see this as a necessity. I pretty much either work at home with the laptop or at school with it. I can see how this would be beneficial for older classroom students, and a communication tool with teacher and students. It is a little confusing to me when I am allowing the public to view this and when I am not.

Wow! I feel like a million bucks! I fiddled a bit with the Rollyo site and was actually able share one of my entries on my blog! That is huge for me. It helped that I was able to go through and read advice through others blogs and comments left for them. I think I feel more comfortable to go back and add and delete things on my site. But I am still so excited that I was able to do it and put something on there that I might really be able to use this year in the classroom. I put a children's lit. search on there so I can search books that I can use with the students. By doing this I can look up a particular book that I plan to use and get ideas from others on how best to interact with the story. Fun!

Wiki is wonderful for so many things as long as others are familiar with it. I guess if they aren't, I could always give them the wiki link. But as I have tried to play with it, it is a little overwhelming to me. I will need to give this more time. I have thought that if I taught my parents how to use this, then we could use wikis to organize for class projects: needed materials, parent volunteers, etc... That way everyone knows what has been taken care of without all the reply all emails. I am sure there are other fabulous ways to use this, but this is where I am now, without having had extra time to play around with it.

I have often wondered about this very topic. Leaving the way we know it and searching for better more interesting ways to teach in order to keep the students learning. It scares me, but at the same time I do see the need for the change. Now, if someone would just fill me in on how we are supposed to accomplish this, that would be very helpful. I can't see a complete benefit from leaving the hard copies, but that doesn't suggest there isn't another way that will help get these students ready for what lies ahead. I don't mind change as long as I understand it, and it has been well thought out. I feel like in the elementary school ages, at least in the primary years, we still need to teach them some of the old fashioned ways, but does that mean I don't totally understand what is coming their way in the future? I just think about reading good books with students and family. Does this stop, and we would get out our very portable laptops and read from those and create our pictures to go with the text? I still think what we have taught thus far is important, but I think there needs to be a better blend of technology teaching as well as the basic fundamentals. I mean what's the point in working on the web and doing different kinds of experiments if the kids can't read,write or do math? But does this mean we just teach these fundamentals differently too? I don't know where to begin to do my part. I am excited and nervous about what lies ahead...and not so very far ahead!
