Gifts for the Gifted – Outnumbered

Terri Eichholz

Several years ago, I thought I would help out the parents of my gifted and talented students by writing about some games, toys, or books that I thought might make good purchases during the holiday season.  I called the series of posts, “Gifts for the Gifted,” and I have continued to do it annually (except for 2019) every November and December.  These gifts are suggestions for any child – not just those who qualify for a GT program. Sometimes I receive a free product for review, but I am not paid for these posts, and I never recommend a product that I wouldn’t buy for my own child.  For past “Gifts for the Gifted” posts, including my 2022 list, you can visit this page. I also have a Pinterest Board of Games and Toys for Gifted Students. 

Outnumbered: Improbable Heroes is on the 2023 list of Mensa’s Games “Recommended to Play.” Because we are getting close to December 25th with today’s recommendation, I’m going to give you the Amazon link to the game as well as the direct link to the manufacturer’s page, Genius Games.

As you can probably guess from the game title, this is a math game. The recommended ages are 8+ and it’s designed for 1-6 players. One thing that I love about it is that it’s a cooperative game, so all of you are working to defeat the “villains”, which are the number cards advancing toward the bottom of the gameboard.

Children will really enjoy the comic-style design of this game, and the hero vs. villain premise. Players each get to choose the hero who will represent them. The heroes also come with superpowers, such as “Add 1 to a Value.” To defeat villains, you roll dice and can use any combination of operations and/or your superpower to “hit” the target numbers on the villains. There are also “Bonus Power” cards that can be earned and used throughout the game. You can learn more about how to play Outnumbered with the video below:

Outnumbered offers a lot of opportunities for strategizing, but all of the players are working together, making this an entertaining way to practice mental math skills without the anxiety. You can also play the game at three different modes, “Training” (ages 4+), “Sidekick”(standard difficulty), or “Hero” (hard difficulty), which makes this a versatile game for classrooms and families.

If you’re more interested in science, Genius Games has two other games that made Mensa’s list this year: Cellulose: A Plant Cell Biology Game and Ecosystem: Coral Reef. Our family played the latter one, and really enjoyed that one as well!

Gifts for the Gifted – The Book of Perfectly Perilous Math

Terri Eichholz

Several years ago, I thought I would help out the parents of my gifted and talented students by writing about some games, toys, or books that I thought might make good purchases during the holiday season.  I called the series of posts, “Gifts for the Gifted,” and I have continued to do it annually (except for 2019) every November and December.  These gifts are suggestions for any child – not just those who qualify for a GT program. Sometimes I receive a free product for review, but I am not paid for these posts, and I never recommend a product that I wouldn’t buy for my own child.  For past “Gifts for the Gifted” posts, including my 2022 list, you can visit this page. I also have a Pinterest Board of Games and Toys for Gifted Students. 

If you’ve got a kid who’s advanced in math and/or a middle school student who loves math, this book just might be an excellent gift. The Book of Perfectly Perilous Math, by Sean Connolly, has 24 “Death-Defying” Challenges for young mathematicians, and the humor with which it’s written is perfect for this age range.

This book is yet another winner that I would have loved to use in my classroom. Posing witty math problems such as, “The Pit and the Pendulum” and “Buried Alive?” The Book of Perfectly Perilous Math categorizes the challenges by your chances of survival. “You Might Make It” problems address Common Core Standards for Grade 5, “Slim to None” are the Grade 6 problems, and “You’re Dead” challenges include Grade 7 standards. If the reader wants some hints, Euclid always has some sage advice to offer, and the solutions are broken down so you can see the type of thinking needed to solve the problem. In addition, there is a “Math Lab” recommended for each problem that gives instructions for creating a hands-on method of seeing the challenge in action. To make the book even more enjoyable, there are amusing illustrations throughout.

Can you avoid death by a giant blade or vexed parents? Will you be able to save Dr. Grog from an untimely demise due to a Brazilian wandering spider’s bite? Only your persistence and mathematical prowess can help you to escape each dangerous situation.

Rather than just handing the book to your gift recipient, I would sit down with them and challenge them to a duel of the wits for each death-defying situation, so you can model the enjoyment of trying to work out a perplexing problem. Don’t worry if you don’t remember middle school math; your opponent will be even more thrilled if they outwit you!

And if you are looking for more entertaining math activities, don’t forget about Math with Bad Drawings by Ben Orlin, one of last year’s recommended gifts!

Sumplete

Terri Eichholz

Maybe the site formerly known as Twitter is circling the drain, but I’m still getting some wonderful resources from it. Case in point is a recent thread started by @kathyhen_ where she asked for more ideas for fast finishers in her class. She helpfully provided a doc that she gives her students, and then many people responded with additional suggestions.

Though many of the sites are already part of my Math Sites That Won’t Make You Fall Asleep and Brainteasers and Puzzles collections, I did see a few that I need to add. One of those is called, Sumplete.

To play Sumplete, you simply click on numbers in each column and row to “X” them out so that they will actually add up to the sums on the right and bottom of the grid. In the example above, 19 is bolded, which means that row already adds up to it, so you don’t need to delete any numbers. However, the middle row needs a number deleted so that it will correctly add up to 16. I can click on the 5, but I need to make sure the 5’s column will then also equal 10 when it’s deleted, as it does.

The Sumplete page gives more detailed instructions if needed. As you can also see in the above example, there is an arrow next to 3×3, which you can click on to select larger puzzle grids. Once you get to 6×6, you can also choose the difficult level. The most difficult is 9×9 master.

Interestingly, the Sumplete page mentions that the puzzle was created in collaboration with ChatGPT, and you can read all about the steps the creator, Daniel Tait of Hey, Good Game, went through for this process. It inspires me to try my own puzzle creation, so I’ll let you know how that goes 😉

Women in STEM Posters and Lessons from Ingenium Canada

Terri Eichholz

I want to thank @MsABahri for sharing the link to these free Women in STEM posters on Twitter (still not calling it the other name, sorry not sorry). There are nearly 100 free downloadable posters on this site from Ingenium Canada, and I am sorry to say that most of the names are new to me. Fortunately, each poster in the series has an image as well as a caption to help us all learn more about each of these amazing people. In addition, you can go to this page for lessons that can be used with the posters, and 3 of the posters have been made into coloring sheets that you can download.

Don’t forget to check out the STEM videos, the interactive Timeline, and the other educational resources while you’re on the site. If your students are studying the ocean, there is also an #OceanDecade link that has specific posters and lessons for that topic.

You can also take the “Implicit Association Test” to get an idea of your own implicit bias when it comes to men and women in different careers.

AI Text to Image Mandalas

Terri Eichholz

I was listening to a podcast this week in which Steven Soderbergh, the famous director, stated, “I am not interesting; I am interested.” This is absolutely how I feel about myself. In fact, I responded, “Curious” to a recent Twitter post asking, “What’s Your Word?” I could spend all day learning new things, and I get really excited when any of those things happens to be something I think might be of interest to you.

On an AI thread in Twitter the other day, someone shared a bunch of images they created with Midjourney, an AI tool. The artwork involved something called, “knolling photography“, which reminded me of natural mandalas. As some of you may know, I used to do a unit on mathematical masterpieces with my 4th graders that included mandalas, and we used many methods to create some. You can see one of my posts about this here. I thought I would jump down this rabbit hole to see if I could create any decent mandalas with some free AI tools at my fingertips (Midjourney is not one of them), and I was pleasantly surprised with the results.

Since Canva is free to all teachers, I started with its “Text to Image” tool, and asked it to make a mandala of quilled flowers. Here is the result:

I also asked for one made with seashells.

Then I asked it to change the style to “watercolor” for another flower mandala. Here was the response:

Even though Canva is free for educators, there are some of you who don’t use it, so I decided to test out another AI chat tool, Bing, in case you wanted a different option. (By the way, if you have the Adobe Creative Suite subscription, you can also try Firefly to do this.)

When my students created mandalas, we worked a lot on symbolism and the meaning of colors, so I started by trying to ask Bing to create a mandala of sports equipment (because that’s invariably what some of my students do). That did not go well. The images were extremely abstract and not recognizable. I finally settled on one where I was able to request a specific type of mandala (spiral dot), the colors red, blue, and green, and a photo of a soccer ball in the middle.

Bing allows you to upload photos, but I didn’t have any success in it making mandalas out of the couple of photos that I tried in the limited time I experimented.

What would students learn from this activity? As I mentioned before, our previous mandala lessons included symbolism and the meaning of colors. We also learned about different types of symmetry and the history of mandalas in many cultures. Creating mandalas themselves helped them to delve more into their own values and creativity. And trying to make them with AI tools will not only bring up philosophical and ethical discussion, but also help them to refine their critical thinking skills to improve their “prompt engineering.”

As Steven Soderbergh also states in that podcast episode when asked about AI, that it’s an iterative tool, but, “It hasn’t experienced anything.” He quotes a Pixar motto, “Be wrong as fast as you can… Just get to the end. If this helps people get to the end of something, fine.” Maybe this is one more option you can give students to get to the vision they have for their mathematical masterpiece — or to create a new vision even better than they imagined.

Free March Digital Breakout and More!

Terri Eichholz

Leonardo the Leprechaun is one of my free digital breakouts, and it’s perfect for March. Students in grades 3 and up should be able to do this breakout in 45 minutes or less. Here is a list of all of my digital breakouts. Along that same theme (leprechauns), I also have a free St. Patrick’s Day S.C.A.M.P.E.R. packet available for download as a PDF. You can search on my Downloads page for digital versions or other S.C.A.M.P.E.R. packets. And you can also head on over to my St. Patrick’s Day Wakelet for even more resources for celebrating March 17th.

Click here to learn more about this free Digital Breakout!

Of course, St. Patrick’s Day isn’t the only holiday in March. There’s Read Across America Day (March 2), International Women’s Day (March 8th), Pi Day (March 14), and World Poetry Day (March 21). You can get links to activities for all of these on my March Wakelet.

By the way, the next potential SpaceX launch date is on Thursday, March 2 (Read Across America Day), and if all systems are go, a very special book will be going up to space. The book, Astronauts Zoom, by Deborah Lee Rose, will be read by an astronaut for the Storytime from Space program! Congratulations to her and everyone who is helping to make this happen!
