Weekly Challenge #6: Dodgson's Doublets

Charles Dodgson, also known as Lewis Carroll, the author of Alice in Wonderland, was both a mathematician and storyteller. One day when several children complained that they were bored, he made up a new kind of puzzle called a “doublet.”  This week, your challenge is to solve some of them!

To solve a doublet puzzle you must change one word to another through a series of steps. Only one letter may be changed at a time and each change must result in a new word.

For example, to turn FOOT into SHOE, we could go FOOT > SOOT > SHOT > SHOE.

Sometimes you have to use letters that aren't even in the first or last word! For example, to turn WET into DRY, we could go WET > BET > BAT > BAY > DAY > DRY.
 
Have fun solving the following doublets. Try to create the new words with as few steps as possible. There is usually more than one way to reach the new word.

1. Raise SIX to TEN
2. Turn EAST into WEST
3. Sail BOAT into LAKE
4. Change MEAN to KIND
5. Make ADD into SUM
6. Shape SNOW into BALL
7. Change HATE into LOVE

Send me your solutions!
Love,
Dr. Edmonds

Weekly Challenge #5: Perplexors!

Perplexors are a type of logic puzzles created by the smart folks at Mindware. The company sells books full of these super fun puzzles, but they also offer a few free sample pages. Those sample pages are here for you to try!

You must use the clues, and YOU CAN NOT GUESS! There is a way to figure out each answer.  Here are some tips:

1. You may not be able to use the clues in the order they are listed. Jump around from clue to clue, and cross it off when you've used ALL of the information in it.

2. If you find a true/"is" answer, circle it. Cross off that choice in the rest of the row, and cross off the other choices in that section of the column.

3. If you find a false/"is not" answer, draw a line through it.

Weekly Challenge #4: Create a Cereal

Last week's challenge required logical thinking...this week, we're using creativity! This is probably SIGNET's favorite Problem of the Day for the whole year, so we're trying it again. 

Your challenge is to draw the front panel of a box for a new breakfast cereal. You can create it on paper or on your computer using your favorite creativity program (PowerPoint, Wixie, etc.).  Your picture should include

1. The name of the cereal
2. A picture of the cereal pieces, possibly in a bowl
3. A mascot for your cereal (like Tony the Tiger, or Lucky from Lucky Charms, etc.)
4. A slogan (like, "Frosted Lucky Charms, they're magically delicious!" or "Silly rabbit, Trix are for kids!")

Now for the best part - you will spin four wheels to get the name of your cereal. You don't get to spin again if you get something weird - you have to take what you get. I trust you!

Get Cereal Name Word 2

Get Cereal Name Word 3

Get Cereal Name Word 4

When you're finished, share your creation by going to FlipGrid. Invite your family to play along - we'd love to see their creations, too!

Love, 
Mrs. Edmonds

This activity came from an idea by Bob Staake, a famous illustrator.

Weekly Challenge #3: Binox
Earlier this year, the fourth and fifth graders learned how to do a logic puzzle called Binox. Today, I bring it to everyone!

Here's an example of what Binox puzzles look like:

Binox puzzle grid

Here's how you play:

1. Each square on the grid is filled with either an X or an O.
2. In each row and in each column, no more than two of each symbol can be touching. Diagonal doesn't matter. (For example, look at the bottom row. There are two Xs next to each other. That means there must be an O on either side because you can't have three Xs touching.)
3. There are equal numbers of Xs and Os in each row and column. (For example, look at the third column. There are three Xs in that column already and 3 empty boxes. So, each box must get an O because you must have equal numbers of Xs and Os.)

In order to save paper and ink, here's where you can play Binox on your computer: Go to Binox online. If you click the book icon at the bottom of that page, you can select a difficulty level. Levels go from 6x6 Easy all the way to 14x14 Toughest. 

I challenge you to complete one 6x6 puzzle from each difficulty level - Easy, Medium, Challenging, and Toughest. If you do it, send me an email to let me know you've succeeded!

Love,
Dr. Edmonds

Hello, friends! Time for weekly challenge #2. This week's challenge is to make a ball land in a cup! Here are the directions.

1. Use a ball that fits into one of your cups at home. (Make sure your parents are okay with you using the cup.)

2. Place the ball on something about 3-4 feet high (toybox, shelf, couch, etc). You can go as higher with the help of a parent.

3. Place the cup on the floor about 5 feet away.  (If you don't have a way to measure, take 5 large steps from where you put the ball.)

4. Now, time to get to be creative! Use toys and supplies that your parents allow to create a path for the ball to follow so that the ball travels your path and lands in the cup on the floor.

(Please use more than 1 item to create your path - do not just use a ramp or a slide. That's BORING!)

 

5. Once you are done, take a picture and email it to me, or make a video of your creation and submit it on FlipGrid: Go to FlipGrid. If anyone else in your family wants to make one, here's the Guest link: Go to FlipGrid as a guest. You can use this link, too, if you don't have your school email address.

 

I have included a picture of a ball and cups on the floor 3 ft, 4 ft, and 5 ft away. 5 feet is the goal, but if you cannot do it, try 4 feet. If that doesn't work, try 3 feet. 

 

Also, answer the following questions:  (If you choose a video, you can answer these in the FlipGrid.)

 

How long did this take you to complete it?

What was the most difficult part?

What worked really well?

What did you have to change?

 
When you're finished, be sure to clean up your mess!

Ball into cup

I miss you!
Love, 
Mrs. Edmonds

Hello, friends! Here's your first challenge...it's called "Animal Mashup." The challenge was inspired by an electronics engineer from Norway named Arne Fredriksen who started making animal hybrids for fun and shared his work on Instagram. Here's an example of his "chorse": 

A chicken horse hybrid animal

Here's another one, his "pear":

A bear penquin hybrid


Your challenge...create your own new creature from a mashup of two animals. Draw and color a picture of your creation, or make it on your computer using PowerPoint (or any other program). Then, give your new animal a name, and hop over to FlipGrid to show us your picture and tell us about it. Go to the FlipGridYou have to use your school email to log in. 
 

If your family members want to try, they can post, too, using our guest link:  Go to FlipGrid as a guest. You can also use this link if you don't have your school email address handy.

I can't wait to see what you create!
