Fun with Fractions! #Math #Homeschool


My son has been interested in fractions, so I printed out this fraction bar freebie on Teacher's Notebook and TPT, broke out fun manipulatives and our calculator.

Once it came time for review, we enjoyed:




and Pizza Fraction Bingo. He really loves Bingo and other board games, so we have several bingo games by this company. Learning Resources also has a number of other matching fraction manipulates (see below), but if you prefer solid wood, especially for little hands, get something like Grimm's Wooden Fraction Circles:

.
or this Lift and Learn Puzzle which also has the words and numbers on it. I love the nice colors, solid feel, and the food-neutral aspect of these alternatives.

There is also plenty of organic learning that you can do with fractions. I started describing their food in fractions long before we with printables and manipulatives. Cooking is a great way to learn and review fractions over and over again. You can have lots of fun baking or pouring water from one measuring cup into another.

Review: Boy Were We Wrong About the Human Body by Kathleen V Kudlinski


We found an awesome series of science history picture books, Boy, Were We Wrong by Kathleen V. Kudlinski. This series presents a nicely summarized history of scientific discovery centered around different themes, all with the purpose of showing readers that our knowledge of science is based on educated guesses. The best part about these books is that they tell your child that THEY might be the next scientist who makes a big discovery that changes science.

The books we read are:

There's one more:

I particularly liked that the Dinosaur book explained that many textbooks, films, and other books feature already out-dated information about Dinosaurs. There have been several discoveries in the last few years that negate what I learned as a kid. Did you know that triceratops and torosaurus are the same dinosaur?

Or that they thought Brontosaurus did not really exist, and now they've changed their mind again?

And, of course, the Solar System book talks about Pluto being a dwarf planet. My four-year-old loves to tell me that Pluto is indeed a planet, just a dwarf one. Poor Pluto!

You can also check out [Kudvinski's website]. She has written many children's books about science and history.

Review: Snap Circuits Jr.


Today we broke out our Snap Circuits Jr. kit. I'm so thrilled with it, and I noticed that it appears to be on sale at [ Amazon ] right now!
The projects in the book have great explanations and illustrations, and follow a very logical progression and start simple, so it is like a 100 science lessons in one kit. I love how the board holds everything together so that it's easier for little hands that are still developing fine motor control.




Having just spent the day checking out different brick-and-mortar stores trying to find 1.5V bulbs and 1.5V motors for what I thought was a simple electronics project, I'm relieved to start with this instead. My 6.5-year-old will still want to build a simple robot one day, but maybe after we've both learned more of the principals behind the crazy DIY projects that require you to buy a 10 pack of flashlight bulbs on Amazon, and a five pack of this and that, until suddenly your cart totals far more than the $20 that this set costs right now

Review: Nellie Nova Takes Flight at Learning Tangent Magazine

My review for Nellie Nova Takes Flight went live today at Learning Tangent: The Common Sense Homeschool Magazine!

Learning Tangent is an interfaith quarterly magazine that has been running since early 2014. Editor-in-Chief Gail Nelsen started this inspiring publication as a bridge between homeschoolers' various beliefs and faiths. Because in the end, we are all homeschoolers!

I'm excited to share Nellie Nova Takes Flight with both my readers and with the readers of Learning Tangent. Like Learning Tangent, Nellie Nova is something that all homeschoolers can get excited about: a book about and for homeschoolers, written by a homeschooler! And did I mention time travel and famous women scientists?

Review: Rattlesnake Board Game #Magnetism #Homeschool #Science

My four and six-year-old love this Rattlesnake board game that their aunt got them for Christmas. The idea is to place a magnet on the board without causing them to clash together.

We like the simple rules, and who doesn't love magnets? This is a game of fine motor skills that's perfect for their age.

When your board starts to look like this, watch out!

Since we love magnets so much and they also got magnetic building tiles for Christmas, we've had a lot of questions about magnets around here. I think that's funny since we've always had magnets of all sorts, including wooden trains. The rattlesnake "eggs" intrigued them!

To explore magnets more, we found facts about magnetism (and video) at Easy Science for Kids, and for something more in-depth, an introduction to magnets video on Khan Academy (my 6yo has an account there. It's free!) and also NASA's explanation of Earth's Magnetosphere.

To round off, here are Elementary Science Experiments for Magnets. My kids have done the first one at Marbles Kids Museum near us, exploring properties and the magnetic field.

Enjoy!

PS. My family also got them buzzing earth magnets as extras for the game, but they're a little bigger than the game magnets. They also buzz better and I think they'd be fun for an extra challenge!

PPS. How are your kids exploring magnets? Share in the comments below!

Negative Space: Sponge Painting

Recently we attended a celebration at a friend's preschool, and I saw beautiful paintings there that made excellent use of negative space. My boys have been begging me to remember to get them more paint, so off to the store we went. But first, I wanted to teach them about negative space:


Negative Space Phase 1: Photographs
You will need:

  1. Toys
  2. Camera (or phone camera)
  3. Light Box (or a white sheet)
  4. Natural Light (or a spotlight)
  5. Basic graphics program such as GIMP
  6. Printer
  7. Kid scissors
We have been studying African animals, so I made sure to include African animals in our selection of subjects. We discussed what the "subject" was and how the white around the subject was called negative space. 

The boys had a lot of fun photographing the toys at eye-level in a light box outside with the flash on. I helped with a few shots to make sure that we got one or two photos that weren't blurry or tilted.

Next, we put the camera's SD card in the computer and took a look at all the photos. The boys pointed out where the negative space was on several photos. I picked the two best and edited them in GIMP to increase the contrast and brightness of the photo, to get what you see above.

Then I printed the photos and asked the boys to cut out the negative space from around the subject. Mr 5.5 was ridiculously excited about this and did a fantastic job. His younger brother was a little iffy on the scissors skills required and cut out a bubble hippo. With his permission, I helped him get the finer details.

Negative Space Phase 2: Sponge Painting
You will need:
  1. The silhouettes cut out by your students
  2. Empty cereal boxes
  3. Pen
  4. Exacto knife or sharp scissors
  5. Paint (we used red, blue, yellow, and white)
  6. Sponges (we used kitchen sponges cut in half)
  7. Containers to place the paint in
  8. Canvas board (8x10")
  9. Tape
  10. Newpaper to lay over your work surface
... and lots of patience for a mess!

First I traced their silhouettes on the backs of cereal boxes and then cut them out with the exacto knife. Then we newspapered our table and got all the paint and sponges ready, and went over our plan to wash our hands after we were done and BEFORE touching anything else. Eek.

The boys chose their favorite silhouette and I affixed it to the canvas board with a circle of tape.We were careful not to let any of the tape peek out over the edges and ruin the shape.

Lastly, our grand finale. The boys had a lot of fun sponge painting the negative space on the canvas. Each of them asked for two colors and the oldest asked for white as well. I painted baby sister a "kitty cat."

First they looked like this:


Then, the reveal!



Since they're canvas board, I might hot glue brackets on the back and hang them on the wall. Yay!

Tips:
  • Don't squish the sponge down on the outline of your cutout
  • If you want two-toned, you may have to let the first color dry first to get nice coverage without blending the tempera paint.
ENJOY!
