The River Crossing Riddle

TED Ed recently featured this “River Crossing Riddle” in its weekly newsletter.  It is similar to the “Bridge Riddle” I recommended on this blog last May.  I think it might be fun to act out the riddle in class to help students try to solve it.  When the video is finished, there are some other riddle suggestions that you may want to investigate as well.

If you enjoy River Crossing puzzles, here is a link to an online interactive one – and another one here from PBS Kids.

SolveMe Mobiles

I was wandering around the “Would You Rather Math” blog the other day and noticed a tweet from the author (@Jstevens009) on his sidebar about SolveMe Mobiles. “It’s challenging and stokes curiosity,” he wrote.

You don’t have to tell me twice.

I immediately visited the link and spent my lesson planning time “testing” the site to see if it would appeal to my students.  Kind of like the way I “test” all of the cookies in a fresh batch to determine if my family will think they are satisfactory…

Fortunately, most websites don’t disappear after you test them (unlike chocolate-chip cookies), so my students will still find plenty of curiosity-stoking challenges to keep them busy when they try out SolveMe Mobiles.

The games are similar to the Balance Benders series of books, which my students enjoy.  They help you to practice algebraic thinking as you try to figure out the value of each of the shapes on the mobile based on the clues that you are given.  Of course, it starts out deceptively simple, like the one below.

SolveMe Mobiles, Level 1
SolveMe Mobiles, Level 1

Both shapes have a value of 5 since the entire mobile is balanced, and has a total value of 10.

There are 200 challenges, so you will eventually reach ones like this:

SolveMe Mobiles #163
SolveMe Mobiles #163

The online interactivity is fun because the mobile will tip if you identify the wrong value for a shape.  Thank you, SolveMe Mobiles, for this much subtler way to say, “You’re Wrong!” than many other games use.

If you are going to want to record your progress  If your students want to record their progress, they can log in.  Otherwise, there is an option just to play without registering.  You can also build your own mobiles.  Or your students can.  I mean, you probably want the students to do it – but I won’t tell anyone if you do it, too.😉

 

Which One Doesn’t Belong?

I just love the people I follow on Twitter.  I get so many great ideas that would probably take a decade to reach me if it weren’t for the #eduawesome people who share resources regularly.

The other day I caught a tweet from @JStevens009 that had a link to a mysteriously named Google Slides presentation, “WODB?”  I opened it to find 52 slides that each showed four pictures.  (John stated that a colleague who doesn’t tweet had shared the presentation.)  Doing a little more research, I found the @WODB Twitter stream, which led me to the WODB website, “Which One Doesn’t Belong?

The website was created by @MaryBourassa, but includes submissions from many people.  The basic premise is to provide 4 pictures that share some attributes, but not all.  Your mission is to explain why each one doesn’t belong, and to support your answer. There are some that are more obvious than others, and that’s where the fun comes in!

For example, in the image  above, it is obvious the nickel does not belong because the rest are pennies.  The bottom right picture does not belong because it is the only one that shows the tail side of the coins.  The bottom left one does not belong because it is the only one that does not add up to 5 cents.  But what about that first picture?

Seriously.  WHAT ABOUT THE FIRST PICTURE?!!!!!!!

Someone tell me what the other 3 pictures have in common that the first one doesn’t. I can’t figure it out.

And it’s driving me crazy.

I just teach gifted students; that doesn’t mean I am one!

Zoombinis

A few months ago I gushed about a Kickstarter campaign that promised to bring one of my favorite computer games ever, Zoombinis, to the 21st century.  Due to the success of that campaign, the Zoombinis app is now available on iTunes and Google Play. Windows, Mac, and Kindle Fire versions will be available later this year.

I was excited to download the app a few weeks ago when it finally became available to Kickstarter supporters. Back when we were allowed to download our own software, I had the game in my classroom for my students to play.  I highly respected the logic skills the game promoted, so when my daughter was younger, I bought a version for her to try at home.

My daughter is now 12, and vaguely remembers playing the original game.  I guessed that she would like the app, but I did not predict the high level of engagement that I’ve observed the last few weeks.

The Zoombinis game is all about logic.  Your goal is to get the Zoombinis to their new home, navigating through perilous puzzles along the way.  Each Zoombini has the following attributes that can be mixed and matched: hair, eyes, feet, and noses.  The challenges are based on those attributes.

For example, the Allergy Cliffs have 2 bridges.  If you place a Zoombini on the correct bridge, the little guy will quickly cross.  If it’s the wrong bridge, the cliff sneezes him or her off.  You have to figure out the “rule” for each bridge.  Only blue noses?  Only the ones with glasses?  Carefully test your theories before too many sneezes make you lose some Zoombinis.

AllergyCliffs

There are several different types of puzzles along the journey. If you aren’t good at one, that’s okay; the puzzle remains on that level until you’ve mastered it. Each puzzle is tailored to your skills, so after a few trips to the end you may end up with different puzzles on different levels of difficulty.

mapOne particular favorite is the pizza puzzle.  You must figure out exactly what toppings Arno wants on his pizza.  Children quickly learn that you need to be methodical because random guesses will end up with a Zoombini or two getting booted off the screen.

Playing Zoombinis together is a fun way for my daughter and I to bond.  It’s also a great opportunity to model problem-solving skills. One of the most frustrating qualities of the game is also one of the best qualities – very few instructions are given.  Watching a child struggle is never easy, but the way his or her face lights up when solving a Zoombinis problem makes it all worthwhile.

The Zoombinis app is $4.99.  This may seem like an enormous amount for an app, but I guarantee that it’s worth it.  It teaches so many thinking skills and sustains interest for a very long time.  If you are a teacher or a parent of multiple children, you will be happy to know that different students can save games on the same iPad so their progress won’t be lost.

This game is cute, fun, and educational.  What are you waiting for? Download it today!

 

Rush Hour Shift

As regular readers may know, my students and I are big fans of ThinkFun games in our classroom.  The logic and problem-solving skills embedded into each one equal the entertainment value, which makes teachers and learners happy.

ThinkFun recently sent us one of their new games to review – Rush Hour Shift.  This name may sound familiar to you.  Rush Hour has been one of the most popular games in my classroom for years.  It’s meant to be a single-player game, though my students usually work in pairs or small groups to solve the increasingly difficult challenges of sliding a car through lanes of traffic to the exit.  The new version, Rush Hour Shift, is a 2-player game – and I predict it will be the new favorite in my classes.

In Rush Hour Shift, there are 3 interlocking plates that make up the traffic grid.  Each player is trying to slide their car to the opposite end.  Different challenges direct you on how to set up the “traffic” on the grid before starting.  Each player is dealt a set of cards, and can only make the moves that are on the cards.  These moves include sliding the other cars around or shifting one of the interlocking plates.

My daughter (12) and I tried the game first.  She beat me two out of three times.  (Spatial reasoning has always been one of my weaknesses.)  I was addicted – but I think my daughter was getting frustrated with playing against someone so obviously beneath her level.

Yesterday, three of my 5th grade girls tried the game out.  They had earned the privilege of  “testing” a game and went into the empty classroom next door to play.   The rest of us were trying to solve some wicked sudoku-like math puzzles, and were soon finding ourselves distracted by the uproarious laughter coming from the game-testers.

I peeked in on the girls, and they were having a great time.  They had easily figured out the instructions, and were taking turns playing each other.  When I asked them if they would recommend the game to others, they vigorously agreed.  Jokingly, one of them commented,  “But not if you want to keep your friends!”  Apparently Rush Hour Shift has the ability to spark some friendly competition.

One thing that we all agreed on was the potential for many hours of fun with this game.  For each of the 10 game set-ups given, there are endless ways the game can be played based on the cards that are dealt and the choices each player makes for using them.

We did receive Rush Hour Shift free to review, but I would definitely choose to purchase one for a birthday gift in the future.

Help Desks

As my students gear up for this year’s Global Cardboard Challenge, they will also be researching a charity to which they will donate the proceeds from their cardboard arcade.  I want them to keep in mind Angela Maier’s mantra, “You are a genius and the world needs your contribution,” and to cultivate their empathy along with their creativity.

As I was thinking about how to inspire my classes this year (many of whom have already seen the Caine’s Arcade videos), I ran across this video from an organization called, “Aarambh.”  Committed to helping students become more comfortable in their schools in rural areas of India, Aarambh found a way to make combination desks/backpacks out of discarded cardboard.  For less than 20 cents in American dollars, a child can be outfitted with this invaluable piece of equipment.  This is a great video to show students so many things:

  • the value of an education
  • how fortunate many of us are to receive a free education with numerous resources
  • how simple, yet creative, ideas can have an incredible positive impact
  • that recycling is not just a luxury but an imperative

Game About Squares

Before you click on the link below, you must agree to the following statement:

“I will not hate Terri Eichholz for the rest of eternity just because she introduced me to this horribly addictive game that got me fired from my job because I couldn’t stop playing.”

Agreed?

Okay.

It’s Phun Phriday, and I found a really fun game that I’ve been wanting to share with you all week.  It’s called “Game About Squares.” It’s online and HTML 5, so you should be able to play it on mobile devices.  (I haven’t tried because I don’t want to start over!)

I am currently stuck on Level 14, and I am not a happy camper.  I’ve been making myself solve at least one new level every time I get on my home computer, but I tried two last night and got stuck.  I’m sure I could find the answer on the internet somewhere but that kind of defeats the purpose.

Right?

Check back with me in a few days and see if I’m still feeling that ethical about it…
