Math Manipulatives: About Virtual Manipulatives Math Manipulatives contains three pages of resources: About Virtual Manipulatives What is a virtual manipulative? In What are Virtual Manipulatives?, Patricia Moyer, Johnna Bolyard, and Mark Spikell (2002) defined a virtual manipulative as "an interactive, Web-based visual representation of a dynamic object that presents opportunities for constructing mathematical knowledge" (p. 373). Static and dynamic virtual models can be found on the Web, but static models are not true virtual manipulatives. Virtual manipulatives have a range of characteristics, such as pictorial images only, combined pictorial and numeric images, simulations, and concept tutorials, which include pictorial and numeric images with directions and feedback (Moyer-Packenham, Salkind, & Bolyard, 2008). Back to top What role can virtual manipulatives play in learning mathematics? According to Douglas H. Christopher Matawa (1998, p. 1) suggested many Uses of Java Applets in Mathematics Education: Applets to generate examples.
The Harmonious Mathematics of Music | Science4All According to legend, the Ancient Greek Pythagoras was once walking on the streets of Samos, when the sounds of blacksmiths’ hammering suddenly gave him an epiphany. Pythagoras rushed into the shop and, as he analyzed mathematically the shapes of the blacksmiths’ hammers, he laid the foundations of music that today’s Rihanna, Shakira and others are building upon. Wait a minute… Are you talking about the guy from the Pythagorean theorem? I am. I’ve been a bit reluctant about writing this article at first because I’m very, very bad in music. The Perfection of Octaves As the story goes, when Pythagoras started to play with hammers, he noticed that two of them were particularly harmonious with respect to one another. What did he find out? The heavier of the two hammers was exactly twice the weight of the lighter one! Exactly twice? I know! Okay, actually, this beautiful story is probably apocryphal… But is there a Pythagoras’ story that’s not apocryphal? That is very surprising… and intriguing!

I never really liked math. I played the school game well so I received pretty good grades, but after I passed the test (even after receiving an A in most cases), those rules, theorems and facts didn’t stick around for very long. The problem was everything was drilled into me, or as I like to think now, drilled out of me. I’m so excited that now, as an adult, I have the time and opportunity to get to know math all over again with my kids. Over the next few weeks, I’m going to take subjects traditionally taught in schools, one subject each week, and show you how they can be looked at in unusual ways. Here’s a list of ten unusual ways to look at math. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. Do you have any ideas about how math is connected in unusual ways to your world? Did you like this post?

Yummy Math BASE Cinque light - Appunti di Matematica ricreativa 1 agosto 2023 Un articolo da ricordare per investigazioni future. Turner H. A., Humpage M., Kerp H., Hetherington A. Science. 2023, Jun 16. La maggior parte delle piante esistenti oggi mostra schemi fillotattici descritti matematicamente dalla sequenza di Fibonacci. Gli autori hanno scoperto che la fillotassi nei fossili del licopode del Devoniano inferiore, Asteroxylon mackiei non seguiva la sequenza di Fibonacci. I risultati della ricerca fanno luce sulle origini delle foglie e dimostrano l'antichità delle spirali non di Fibonacci nelle piante. 25 luglio 2023 Beh, ho imparato che scissor congruence è un termine tecnico. 26 giugno 2023 Ultimamente ho potuto confrontare l'edizione inglese con quella italiana del libro sugli insiemi di Abian: Alexander Abian, The Theory of Sets and Transfinite Arithmetic, Saunders, 1965. L'edizione inglese di questo libro è di circa 400 pagine mentre l'edizione italiana citata è di circa 800 pagine. E' lunga il doppio. 22 giugno 2023 Alexander Abian (1923-1999)
Algebra I - UTeach Austin: PBI The following projects were created by UTeach PBI students following content guidelines of either the second or fifth 6th weeks of the Austin Independent School District's scope and sequence. *** Design a neighborhood: The students will be working in groups throughout a four-week PBI unit centered around designing a block for a new neighborhood being built in a city. In the final artifact the students will create a blueprint design of a block of this new neighborhood, consisting of four buildings. These four buildings will have set specifications defined in the attached rubric for the final artifact. *** Car Trip: The students are planning for a senior road trip to five different cities across the United States. *** Fun Vacation: The goal of the project is to plan financially for an international trip. *** Let's Make Some Money!
The right spin: how to fly a broken space craft June 2006 On the 25th of May 1997 an unmanned cargo ship named Progress crashed into the Russian space station Mir, tearing a hole into Mir's side and sending it hurtling through space. In his desperate attempt to save Mir and its crew, NASA astronaut Michael Foale had no choice but to get right down to the maths that governs space flight. Crunch The space station Mir, manned by NASA astronaut and scientist Michael Foale, Flight Engineer Alexander "Sasha" Lazutkin and Commander Vasily Tsibliev, had been put in orbit around Earth to test for the first time the feasibility of long-term human habitation in space. The space station Mir. But this wasn't a routine docking manoeuvre. "Why were we taking this risk? If you imagine guiding a seven ton truck into a narrow parking slot by remote control, only with the help of a small black-and-white monitor and subject to a time delay, you get some idea of the difficult task that was facing Vasily Tsibliev, who was to execute the docking manoeuvre.
