PCCL | Physique Chimie Collège Lycée : soutien gratuit en animations pédagogiques de cours et exercices corrigés de sciences physiques. EPI | nouveau programme réforme rentrée 2016. C'est la nouvelle adresse de physiquecollege.free.fr. Denne matte-oppgaven for 14-åringer skaper hodebry over hele verden Matteoppgaven øverst i denne saken er ment for 14-, 15-åringer. I følge engelske The Guardian har den skapt hodebry for folk over hele verden. Det inkluderer organisasjonen i Singapore som står bak den. Greier du å løse den? Står du helt fast, finner du en link til løsningen nederst i denne saken. Løsbar Oppgaven kan ved første øyekast virke uløselig, men det dreier seg faktisk om ren - om enn temmelig finurlig - logikk. Såpass vanskelig er oppgaven, at organisasjonen som står bak den har skrevet et brev som i dag ble publisert på nettstedet mothership.sg, for at foreldre «ikke skal bekymre seg unødig». I brevet går det fram at det ikke er slik noen trodde da oppgaven spredte seg på nettet i går, at den er ment for skolebarn i ti-årsalderen. Derimot er den hentet fra en konkurranse i en «matte-olympiade», Singapore and Asian Schools Math Olympiad (SASMO), som ble holdt den 8 april i år. Lettet? «Dette er et vanskelig spørsmål som er ment å skille ut de beste studentene.
qbyte: Nick's Mathematical Puzzles Welcome to my selection of mathematical puzzles. What's new? See puzzle 160. The math puzzles presented here are selected for the deceptive simplicity of their statement, or the elegance of their solution. Explaining how an answer is arrived at is more important than the answer itself. Each puzzle is assigned a level of difficulty of between one and four stars, with four being the most difficult. The source for each problem is given at the bottom of the solution page. I welcome feedback of any kind. Some brief biographical information. Nick Back to top

The 10 Best VR Apps for Classrooms Using Merge VR’s New Merge Cube Recently, the world of virtual reality was shaken up when the popular Merge Cube by Merge VR dropped in price from $15 to just a dollar at many Walmart stores. When using specific apps, these cubes showcase different experiences as you rotate the block around with your hands. If you haven’t held a Merge Cube yet, they're made of a soft rubber material that’s comparable to a stiffer stress ball. The Merge Cubes work with most mobile phones and tablets, and the apps are found in the Google Play and App Store. While educators are flocking to scoop up hot deals at their local store, many are now wondering how to use them in the classroom. 10. The Th! App Store | Google Play 9.

Stier og kretser - Matematikksenteret Skrevet av Mike Naylor, 1. juni 2015 Grafteori og topologi er to områder i matematikken som handler om hvordan punkter i rommet er relatert til hverandre. Mange av ideene fra disse områdene er tilgjengelige for elever - og ikke bare er de temaene morsomme og spennende, men de bygger også romforståelse, logisk resonnement og problemløsningsferdigheter. En oppgave jeg husker godt fra min barndom er å tegne dette bildet av en konvolutt med en strek – uten å løfte blyanten fra papiret og uten å krysse streken. Denne klassiske oppgave har utfordret folk i generasjoner. Hvor skal vi starte? Her er flere oppgaver som du og elevene kan prøve. Broene i Königsburg Dette er et berømt historisk problem. Kan elevene finne en vei som krysser alle broene gang og bare én gang uten å svømme over elva? Nå er oppgaven lik dem vi har nettopp gjort! Leonard Eulers artikkel på dette problemet startet hele feltet av grafteori!
