    With a turn of a kaleidoscope, the colors change and swirl - with a turn of one of these puzzle tiles, will you finally find the solution to the kaleidoscope puzzle? A simple concept, this logic puzzle is composed of 6 tiles with clear and colored sections. They only include the 3 primary colors (red, yellow, and blue), with each tile including two colors in different sectors. Forty cards, with varying degrees of difficulty, challenge you to recreate the picture on the card with a certain number of tiles. You must identify and stack the correct tiles to replicate the picture, sometimes stacking two primary colors to make a secondary color (like purple). Solutions included. ~ Megan

    Sudoku puzzles have exploded in popularity in recent years, and this product allows you to enjoy the logical puzzles with colors instead of numbers. Instead of using numbers from 1-9, Colorku uses nine differently colored wooden marbles on a large wooden board. The high-quality wood board measures 13.5" x 13.5" and is divided into nine rows, nine columns, and nine 3 x 3 squares. It has 81 wood marbles in 9 vibrant colors. The board and marbles are covered with a plastic tray that holds the balls on the board when storing, and flips over to serve as a ball holder while playing. The board comes with 100 different puzzle cards that come in four different difficulty levels and tell players where to place the first few marbles. The solution to each puzzle is achieved when the player ends up having one and only one of every color ball in each of the nine rows, columns, and 3 x 3 squares. Solutions are included. There's even a color conversion card that shows you how to alter any Sudoku puzzle from any book or news-paper and solve it using your Colorku board. Think the 100 puzzle cards that come with the game won't be enough? Luckily, there are a few Expansion Packs, which offer additional puzzle cards at a variety of levels. Each pack offers 100 puzzles with solutions. The Beginner Puzzles are fairly simple, the All Level Puzzles offer puzzles for four different difficulty levels, and the Advanced Puzzles will drive you crazy. The durable wooden game and fun yet challenging puzzles will be enjoyed by new and old Sudoku fans alike. ~Rachel

    Programming isn’t just for the computer in this game! The idea is to “program” your way through each puzzle, using a specific combination of movements. Included in the game is an avatar, a portal, various move tokens (actions your avatar can take such as jumping, sliding, or running), power crystals, and enemy tokens, along with a map book and guide book. The map book contains puzzles of increasing difficulty with color-coded paths, which indicate which movement you need to go down the path, numbered spaces for power crystals, your avatar, and the portal. The guide book is your “program”: you place movement tokens on the various slots available in that puzzle, and then “run the program” by moving your avatar based on what tokens you placed in the guide book. The goal is to program your avatar to collect all gems, fight enemies, and navigate your way to the portal. Once you have a successful program, you can move on to the next level! But be warned: though the early levels are simple, there’s only one solution to each puzzle. Later puzzles feature loops, one-way paths, and non-linear programming logic in the guidebook. While the main goal is to demonstrate how computer programs “think”, the game is also great for developing planning, sequential logic, and problem-solving skills. Code Master is a single-player game, but can easily be passed around level-by-level for some family fun!

    This Tetris-like puzzle features 12 different shapes of between 3 and 5 beads with thin connecting plastic. The puzzle board is a 5 x 11 region of dents in which you will configure your shapes. The object of the game is to fit all 12 shapes on the Kanoodle board, starting with the positions on the cards. As the cards get harder, you will start with fewer and fewer puzzle pieces. Each setup has hundreds of possible combinations but just one solution. It can get quite frustrating when you end up with one bead off the board and one open spot, but the more you try the closer (and farther) you can get. Once you master the 2D setup, you can play 3D Pyramid Kanoodle with the same key concept but one challenging twist - use all 12 pieces to make a pyramid. I hope you find this as fun and challenging as I did.

    Subtitled "Beginning Latin for Homeschoolers and Self-Taught Students of Any Age," I could see this book serving as a great introduction to Latin for the family who is not sure they want to jump right into a full-fledged Latin course. Of course, it would be just as useful for an older student (or even Mom and Dad), if they have never studied Latin but want to learn it on their own. The course was designed out of necessity by author William E. Linney, after he was asked by a relative to teach Latin to her children. He set out looking for a course that would not require a Latin teacher, was self-paced, self explanatory, offered lots of practice exercises, was non-threatening, and inexpensive. When he couldn't find a course that suited his needs, he designed this one. The book contains 134 lessons, which are short (usually less than a page in length), un-fluffy, and incremental in progression. Lessons strike a nice balance between introducing new vocabulary, explaining simple grammatical concepts, and memorization of noun and verb forms. No lesson covers all of these tasks, but instead focuses on one objective and covers it well. Lessons that introduce new Latin vocabulary feature a new Latin word, its English meaning, and sometimes a pronunciation tip. This is usually followed by about ten sentences to translate. Lessons on grammar are also bite-sized, and different forms and cases are introduced gradually. As they are introduced, they are added to a chart, and students will translate sentences that use the forms and cases that they have learned. As charts are filled with endings or forms, students may be asked to memorize them, to aid in future lessons. Just for fun, "Latin Expressions" are scattered throughout the book. In each one, the author takes a common Latin phrase like "caveat emptor," or "etc." and explains the Latin history behind each phrase. Don't underestimate how these little "sparks" of knowledge whet your appetite to learn more! By the end of the book, students will have stockpiled basic vocabulary of around 100 words, be comfortable translating simple sentences in Latin, and have a grasp of basic Latin grammar.

    There are a couple of aspects of this course worth noting. First of all, because the book is more of a text than a worktext it is not designed to be consumable. For translation purposes, the author recommends translating the sentences in a separate notebook. If extra practice is desired, you may wish to translate the sentences back to the form given in the lesson. Secondly, while we all realize that pronunciation is very difficult to teach "out of a book", the author has considered this, and has come up with an ingenious solution. He has provided MP3 audio files free of charge on his website, which can be downloaded and used with the lessons. As an added bonus, you can choose from either classical pronunciation or ecclesiastical pronunciation. Audio commentary on the lessons and a host of other helpful resources is also included on the website. Lastly, this course would be excellent prep for an older student who will be studying Latin in high school or college who hasn't had the benefit of laying a basic Latin foundation earlier in life. Upon completion of this book, I think students would be more ready to tackle Lingua Latina, Oxford University Latin, Henle Latin, or Cambridge Latin, than if they were starting off cold. Latina Christiana I or other complete courses designed for younger students could also be considered reasonable continuations, although there would be much more overlap/review between courses. This is a terrific way to get started in Latin and I am glad that the author did not find what he was looking for to teach Latin, because he has certainly written a course that fulfills all of his goals! – Jess

    There are so many puzzle games around, it's difficult to find one that stands out from the pack. IQ Twist differs from the rest in several regards – its simplicity, its small size, and its originality. To play, you decide which of the 100 puzzles you want to do, and fit pegs into the board to match that puzzle. Then you try to fit all the twisty puzzle pieces onto the board and over the pegs– matching the color of the piece to the peg it fits over, of course. Each puzzle has only one solution, making some of them downright impossible. An excellent travel game, and a great way to boost IQ and spatial reasoning. ~ Mark

    The word 'Algebra' can strike fear into the hearts of many, but Critical Thinking Press has done their part to calm your math nerves and prepare students for higher level math in Understanding Algebra. The newest member of the Mathematical Reasoning line is a full one year algebra course for students at the junior high and high school level in a consumable format.

    The information in this worktext is a user-friendly format and presented in a step-by-step fashion. The text makes a connection between the arithmetic of the elementary years to the algebra they need to succeed in high school math. Twelve chapters begin with the basics and build upon each other Our number system, Evaluating Expressions and Solving Equations, From Words to Algebra/Translating and Solving Word Problems, From Words to Algebra/More Word Problems, Inequalities, Polynomials, Factoring, Working with Radicals, Linear Functions, Systems of Equations and Inequalities, Other Types of Functions, and Working with Algebraic Fractions.

    The author begins the book with a simple explanation of "What is Algebra," and then jumps right in. Each chapter is 20 to 30 pages in length and broken into topics. Each topic or lesson offers the student explanations and examples in a very visual fashion. Colored charts, illustrations, and graphs are incorporated for clarity of explanations. Within the lessons, students will be asked questions to assure they know the concept being presented and a 'more practice' section rounds out the lesson. Sets of 'Enrichment Problems' are scattered throughout the chapters to offer additional practice in higher-order thinking using plenty of word problems. There are no chapter tests in this book, so you would need to assess your student's understanding of the concepts by other means grades from the practice sets and exercises might be your best tool for assessment.

    New for the 2017 edition are chapter reviews covering and a final exam.

    A glossary that includes algebra vocabulary and an answer key are found at the back of the book. These are answers and not solutions. A helpful reference page is included. Students will learn about the history of math as they learn math strategies to help them with algebra and beyond. 378 pgs. pb. Reproducible for home and single classroom use. ~ Donna

    50 challenges, countless configurations! Interlock is a game of logic that challenges the player to think outside the box. The objective is to create connected geometric shapes using the twelve 1x1x2-inch blocks in a manner that hides all visible sockets or plugs. Interlock seems deceptively simple at first, but spikes in difficulty rather quickly, becoming a true test of skill, inventiveness and spatial reasoning. A booklet is included which offers hints as well as a solution to all puzzle configurations. However, another interesting facet of this game is that the answers they present are only one of many possible resolutions to a puzzle! ~ Nick

    A logic game with a Noah's Ark theme! Each animal wants its own place on the ark—your challenge is to fulfill those tricky requests. For example, the kangaroo wants to sit next to the lion, but that's the spot where the panda wants to sit to chat with the zebra. Oh, and the giraffe doesn't want to sit in the back. This game includes a simple, slotted wooden ark, 7 painted wooden figures (Noah, giraffe, kangaroo, lion, hippo, panda, and zebra), and a ringed card deck with 60 challenges. The front side of each illustrated card presents a challenge to complete with visual clues (no reading; some with numbers) that show where certain animals want to sit. Try to solve the puzzle by arranging the animals in an order (and facing the directions) that make all the animals happy. Challenges progress through four levels of difficulty; solutions are on the reverse side of each card. For one or more players.

    I double dog dare you to try this puzzle! It seems innocuous enough, 12 brightly colored plastic shapes that look like children's toys. Each pentomino equals 5 cubes and loosely resemble letters. These have been around a long time under different names like Polyominoes and Hexus, as mathematical recreation. The book of patterns is your challenge. I tried the first page of puzzles thinking they must be the easiest and won't take long to finish. Boy, was I wrong! Pentominoes are quite tough to solve. I thought I must be missing something simple, so I asked other people to have a go. We were all stumped and engaged in this compelling math puzzle. The book states that ages 8 and up should be able to complete the patterns, but I would say it is for older students and adults. Even a child with a very mathematical, logical brain will be challenged by this. Just trying to get them back in the box was a puzzle in itself. The book has 365 puzzle patterns to try and follow. The solutions are in the back and an introduction and some tips are in the front. The pieces themselves store inside the book in a plastic case. Kids can even create new designs and record them on graph paper. I would call this one deceptively simple and a lot of fun! Keep your brain "in shape" for a long time to come. 96 pgs, spiral hc. ~ Sara

    During my senior year of high school, I would have welcomed this book with open arms. I had decided I didn't need to study for the ACT, but a week or so before the test I began to doubt the wisdom of my choice. This Princeton Review book is like a cram session for the ACT. It gives tips and strategies for taking the test, as well as an overview about the different sections on the test, types and formats of questions, and other general information. It presents ten simple steps to improve your score on the test and gives dozens of practice questions (with answers) and drills so you can practice the testing techniques given.

    This book is what House That Cleans Yourself and Get Yourself Organized are purposefully not - a canned organization system. (and a very good one!) If you're looking for a book with the best tips on organization and minimizing clutter while maximizing space and efficiency in your home, this is an excellent resource. Author Barbara Reich is a true Type-A personality who organizes for a successful living. Her philosophy is simplicity and consistency room by room, and her system is simple: purge, design, organize, and maintain. In person she likes to get down to business (less talking, more organizing!), and her book is the same way - less fluff, just straightforward solutions. She begins with a brief chapter introducing her system, the "ten commandments of organizing," and tips on tools of the trade. Then, you are ready to transform your home. Each chapter deals with a different room/space of your home, which you can tackle spaces in any order. Furthermore, each chapter is broken down into smaller sections by common or troublesome items specific to that space, so Barbara does a thorough job taking every single area through her four-step process. From clothes to lighting, furniture to digital documents and pictures, and toys to toiletries used once a week or less, no object will be left unevaluated! Chapters cover the entryway and front closet, master bedroom, children's bedrooms and play areas, nursery, bathroom and linen closet, utility closet, kitchen and pantry, family and living rooms, home office, storage areas, and a bonus chapter on organizing for holidays. Every section is full of no-nonsense advice and appealing, workable solutions. Even if you don't take all her advice on minimizing, or have different decor ideas, you will greatly benefit from her thoughtful design and organization tips. Hardcover, 242 pages. - Steph
