Freebies and a Cyber Monday Sale


It's hard to believe December starts tomorrow!  For the first time since I can remember, I actually got to RELAX this year on my little 2 1/2 days off.  Our district is sending home report cards the week after next so I took full advantage.  I ate, I exercised, I cleaned, I decorated, and I added to my Cyber Monday wishlist over on TPT.  That's right, Teachers Pay Teachers is once again having their Cyber Monday (plus Tuesday) sale on December 1st and 2nd!  You can save up to 28% off of your purchases by entering promo code TPTCYBER at checkout.  My whole store will be a full 28% off as long as you remember the promo code!  

I'm linking up with Jivey to share with you some of my own products that are on a lot of people's wishlist right now, as well as one that's in my own wishlist.  One thing I have in my own wishlist are these gift tags from Creative Clips.  So cute!
 




Here are a few items from my own store that are in high demand and have kept my own students engaged in their learning each year during the second trimester:

This Long Division Games Bundle provides students with the repeated practice they need to internalize the long division process.  By turning this practice into games and hands on activities, the kids actually enjoy honing their long division skills!

Like the division bundle, this Equivalent Fractions Activities 3 in One Bundle is hands on, and helps students enjoy their math block. 










If you're looking for a more complete fractions unit, I am launching my finished FRACTIONS UNIT on Monday, just in time for the sale.  This product has been months in the making, and I wanted my readers to have the opportunity to get the maximum savings on it.  Check out my most recent product and save 28%! 







If you really want to plan ahead, Poetry Month is traditionally in April.  This is the time to save big on a complete poetry unit for fourth grade.  It has everything you need for high stakes test prep.  This Fourth Grade Poetry Mini Unit helps students meet the standards while also providing opportunities for creativity and appreciation for a variety of poetic forms. 





  
And finally, if you're looking for my best deal, you can save 28% on my largest bundle, my 5 US Regions Unit Plans Bundle.  Normally priced $25, it will cost just $18.75 for two days only! 

So start filling your wishlist, and come back Monday and Tuesday to save a bundle on some fun, engaging resources for your class. 





As a thank you for following along I also wanted to direct you to a few of my favorite seasonal freebies.  There are a few must-haves if you are teaching elementary, and a few if you are specifically teaching fourth. 

1.  Tissue box hygiene reminders.  I rubber-band these to each tissue box in my classroom as a not so subtle reminder!  If you have a sink in your classroom, the place to hang a reminder is not over the sink (where they are already washing their hands).  It's on the tissue box itself.  Slow the spread of germs this flu season!







2.  Holiday Aid for Low Income Students   Here's a seasonal freebie for your class.  It's designed to help target assistance for your lower income students if you have funds from the PTO to provide them with a little something for the holiday.  I'm lucky enough to work in a school where we give to the families in need every year, and this page will help you get started with that.







3. Mentor Sentences for Complete Sentences.   Many grammar tasks ask kids to find what needs to be fixed in a sentence.  As a result, kids are exposed to models of incorrect writing!  Stop reinforcing models of common grammatical errors.  Mentor sentences require them to analyze quality, model writing, then explain what makes it so.






4.  Kinesthetic Map Activity.  This is a fun whole group activity that gets kids practicing continents, countries and directions.  It's not every day you let your fourth graders crawl around on the floor to learn, but I think you'll like this one as much as they do.








5.  Using one half as a benchmark coloring page.  This coloring page reveals a "mystery picture" as kids determine if each fraction is greater to, less than, or equal to one half.  The writing component allows you to differentiate as well as gives students practice justifying their answer. 






I hope you enjoy the freebies and save lots of money at TPT.  Do remember to enter the promo code TPTCYBER when you shop on Monday (and Tuesday) in order to get the full 28% discount.  One new product that I'm launching today will be FREE for the next two days only is Line Up!  Compare and Order Fractions Movement Activity.  This is a great way to get the whole class up and talking about fractions, justifying their responses with reasons and details.  And I finally had a little time this week to polish it up so that you will be able to introduce it to your class with confidence, just in time to save you 28%. Happy bargain hunting!

How to Teach Density (Solids, Liquids and Gases)

 
Last time I told you about how I introduce my fourth graders to the states of matter.  Today I'll share how to teach density.  Part of our states of matter unit includes an understanding of density.  We tested out a variety of objects.  Although kids as young as preschool can perform "sink or float" tests, fourth graders still have some misconceptions!  I wrote on the board:



 
Large             vs               Small
Protractor                         Eraser
Scissors                          Foam dice

How to Teach Density of Solid Objects:  Sink or Float?

How to Teach DensityMany students thought the larger items would sink, while the smaller items would float.  They were only half right!  Our tests showed that the eraser sank, although the plastic protractor floated. 


As a result, we determined that size and weight do NOT relate to density.  Density is about how tightly packed molecules are.  Tightly packed molecules sink, while loosely packed molecules float. 


A real world example I gave was the ship they boarded on a field trip earlier in the year.  Obviously that floats!  And it's bigger than any item they tested today. 


To bring the point home, I have them test materials of their choosing.  They record their predictions and the results.  



Another misconception some fourth graders have about density is that all gases float and are equally dense.  Many don't believe you when you tell them gas takes up space.  And the idea that some gases are lighter than others doesn't stick.

 

How to Teach Density of Gases



The best tool to help kids understand about varying density of gases is balloons!

"Oh yeahhhh!  Helium!"  Many kids know that if you blow (carbon dioxide) into a balloon, it won't float.  You need to fill it with a helium tank.  What they may not understand is how helium is stored and measured.  Otherwise how can you tell if you're buying the right amount for all your balloons?
 
 


I explain that when you rent a tank of helium, they charge for tanks of gas by volume.  Volume is similar to liquid capacity.  This chart shows how big the tank must be, depending on how many balloons you want to fill.  

The size of the balloons matters too!  The larger the balloon, the more helium you need to fill it.  If you have sixty 14 inch balloons, you need a larger tank than if you have sixty 9 inch balloons.  

With our Student of the Month assembly this month, we were able to do double duty with the decorations/science demonstration.  I found this helium tank on Amazon.  The kids got to prove how many balloons could be filled with our little tank, and the cafeteria got a little more festive in the process!
 
How to Teach Density of Liquids


The quickest way to teach density of liquids is attempting to mix oil and water.  After making predictions, students partnered up.  One poured water into a cup of oil, and the other poured oil into a cup of water.  Of course the oil, being less dense, rose to the top.


This was a fun unit, which I've made available here on TPT.  Along with the activities you've seen on these blog posts, I've included several other printouts for you:
http://www.teacherspayteachers.com/Product/States-of-Matter-Unit-578103• Density and Mass lesson with activity sheet
• Mixture and Solution lab sheet
• Water Molecule writing prompts (with vocabulary) expository and narrative writing prompts
• Matter Test (multiple choice, open response, and answer key)

Multimodal States of Matter Activities

 

You know those science chapters that have the life sucked out of them?  Our textbook is probably the WORST.  Luckily I was free to create my own unit with multimodal states of matter activities. 

Some chapters I can use as  a jumping off point to my instruction, but I really had to start from scratch with this one.  Not only is this is a concept that needs to be hands on instead of read, but recently I've also started using the miracle of YouTube helps bring the scientists right into the classroom.

 

Multimodal States of Matter Activities
 

States of Matter ActivitiesDefinition and Examples

After defining three of the states of matter (we don't cover plasma in fourth grade, although I do let them know that solid, liquid and gas are not the only three states in existence).


I add student generated answers (in a think pair share) to our anchor chart for examples of solids, liquids, and gases.


I also like to write a few of their questions for further research.

 

Kinesthetic States of Matter Activities

Then I like to do some activities from my States of Matter Unit to get them moving around and pretending to be molecules!  One of my favorite states of matter activities is when we pretend to be solid molecules, so we sit close together and hardly move.  As liquids we move around a defined area (the reading rug) and as a gas, I tell them, "Now fly!"  I get lots of laughs, and model flapping my arms and power walking around the whole room.  They follow suit and get the idea!

Music

To keep the definitions and concepts fun, I play Mr. Parr's Four States of Matter Song.
Even though they are more geared toward middle school, they are current and get the kids excited about science class.  
Visual Arts

When we talk about matter changing state, the kids are pretty comfortable with the concept of freezing and boiling water.  However, the idea that glass can be a liquid (or even a gas on the sun) is hard for them to swallow.  Once again, I turn to videos to drive the point home!

The Chrysler Museum of Art has a great video on blowing glass, including the art and science involved in working with liquid glass (also known as molten glass).  The artist reveals the temperature they have to heat the glass to turn it to liquid.  I tell them, "Don't try this at home kids; your oven can't get that hot!"  John Pomp's Studio focuses more about tools used to create glass ornaments, and makes for a nice enrichment video for kids who want to learn more.  

These activities all lead up to learning about density, which leads us to a better understanding of weather later in the year!  Next week I'll tell you more about our density lab reports and tests.
