Browse Elementary Puzzles Stars indicate particularly interesting answers or good places to begin browsing. Selected answers to frequently posed puzzles: A hen and a half... Measuring with two containers. Heads, legs: how many animals? How many different ways can you make change for a dollar? We discovered that there are 204 squares on a chessboard and found that you would add the different squares - 1 + 4 + 9 + 16 + 25 + 36 + 49 + 64. There are three more people in front of Clancy than in front of Nancy, and twice as many in front of Mary Ellen as in front of Nancy. If you take a two-digit number, add the digits, and subtract the sum from the original number, why is the answer always a multiple of 9? I am looking for some information on a math game called Petals around the Rose. How many rectangles can you make with 10 small squares? I have been given a list of numbers without any plus or minus signs and I have to place the signs between the digits. Leave the numerals in this order.

Tarsia
With this software you will easily be able to create, print out, save and exchange customised jigsaws, domino activities and a variety of rectangular card sort activities. The activities created using this software can be presented in printable form, ready to cut out. Formulator Tarsia known earlier as Formulator Jigsaw is an editor designed for Teachers of Mathematics creating the activities in a form of jigsaws or dominos etc for later use in a class. It includes the powerful equation editor for building the math-expressions for the activities. An advanced feature of text placement along the side of the shape makes this tool irreplaceable software for fast activity creation. Formulator Tarsia became a powerful tool for learning activities since it supports the activity templates. Formulator Tarsia installation package contains samples kindly offered by: Hermitech Laboratory highly appreciates these contributions.

Demystifying Math Struggles
Introduction Since the YCDC website began in 2007, we have received many requests about how best to help dyslexic students struggling with math. We reached out to Chris Woodin, the head of the Math Department at Landmark School, a respected school that specializes in teaching students with language-based learning issues, to help us find alternative methods for mitigating common math struggles that seem to accompany dyslexia. Woodin offered many helpful strategies to help address them, and we hope that it will help other teachers and parents who are looking for ways to support dyslexic children with math. Breaking Down Math Excelling at math, or just even being able to pass the requirements, draws on many different skills and ways of thinking—it calls on conceptual, logical, and spatial reasoning, but it also often requires neatness, exactness, and computational skills.

Take a Penny and Take Regrouping Out of Subtraction
"Take a Penny" is a 2 step strategy that allows students to subtracting across zeros without having to go through the complicated steps of regrouping. In fact with "Take a Penny", students can subtract across zeros without regrouping at ALL! I learned the "Take a Penny" strategy last summer, and it has transformed the way my students subtract. I was at one of those workshops that you really don't want to be at but are required to go to, and boy was I amazed. The man that came to talk to us knew exactly how it felt to be in our shoes and did not waste one second of our time. And it works every time, no matter how many zeros you have. I created a 23 slide PowerPoint presentation to help students and teachers master this innovative strategy.

La découverte d'une "tuile" historique secoue le monde des mathématiques
SCIENCES - Une équipe de mathématiciens a bouleversé le monde des maths en découvrant un nouveau type de pentagone capable de "paver un plan", c'est-à-dire que les tuiles peuvent s'assembler sur une surface plane sans qu'elles ne se chevauchent ni ne laissent de trous. Seuls quinze pentagones de ce type ont été découverts jusqu'ici. On n'en avait pas découvert depuis trente ans. C'est presque aussi impressionnant que de découvrir un nouvel atome, a déclaré Dr. Casey Mann, maître de conférences en mathématiques à l'université de Washington Bothell et membre de l'équipe. L'équipe a fait cette découverte grâce à un programme informatique conçu pour l'occasion. "Nous avons découvert la tuile en faisant une recherche exhaustive sur un ordinateur grâce à un ensemble de possibilités très large mais fini", a expliqué Casey Mann au journal Le Guardian, en ajoutant que l'équipe avait été "un peu surprise" de découvrir un nouveau type de pentagone. Le nouveau pentagone.
