Enheter. Hello Guzzlers.

It is with huge pleasure that I introduce today’s puzzle, which is already a big deal in Japan. It’s called Menseki Meiro, or Area Maze, and I hope you find it as brilliant as I do. Area Maze is the creation of Naoki Inaba, one of the world’s most prolific inventors of logic puzzles. He came up with Area Maze after being asked to come up with a puzzle by the head of a crammer school in Japan. The puzzle is utterly simple to explain: find the missing value, which is denoted by a question mark highlighted in grey. Here’s what makes the puzzle genius: You are NOT allowed to use fractions in the solutions. Now you’ve got the hang of it, try these four.

Naoki Inaba has been devising puzzles since he was a teenager. I asked him about Area Maze. In fact, it is so popular in Japan that now Area Maze problem books are published. Ill be back later today to show you how to solve the more difficult puzzles. Meanwhile, here’s how to solve the very first one.

Metoden som gynnar långtidsminnen – Spaced Learning!

Många faktorer kan påverka vad och hur vi minns. När vi lär oss något kopplas neuronernas synapser samman i ”minnesbanor”. Vi vet att repetition stärker sammanlänkningen mellan hjärncellerna och då får vi ett mer varaktigt minne. Upprepad repetition stärker minnet ytterligare. Relativt nya forskningsrön (Douglas Fields, 2005) visar att långtidsminnen bygger på att våra synapslänkade hjärnceller har tillverkat ett protein, CREB, i anslutning till inlärningen. Vi skulle inte kunna tänka oss gå på gym och träna dag efter dag utan den viktiga uppbyggande vilan emellan. Så hur kan vi då ”gym-träna” elevernas och våra egna hjärnor så det vi vill lära oss hamnar i långtidsminnets avdelning? Spaced Learning är en evidensbaserad metod där undervisningsaktivitet och paus varvas enligt ett optimalt tidsschema (Kelley & Whatson, 2013).

Under samma lektion gås stoffet igenom 3 gånger med 10 minuters paus däremellan. Rektangels area. Articles For Educators - Lesson Plans and Activities. Veckomatte6Web.pdf.

PI. Geometri. Games. Mastering Multiplication Facts - Incentives Your Kids Will Love!!!! A Little Magic to Start the Year off Right. I just finished a Magic Number game/trick I will be playing with my students at the beginning of the year.

A Little Magic to Start the Year off Right

It's a great starter because I make my kids think I am magic and can read their minds! This freaks them out just a little. LOL ***Disclaimer: It's not really magic - Just a number game. Incase some of you were wondering! It's VERY easy, and if your students can add one and two digit numbers they will be able to do it too. Basically, there are 5 magical circles and the children will choose a number and you will ask them questions to figure it out. I have seen a similar math magic trick, but it was hand written and an old, faded copy. Does anyone have a "magic" trick or game to intrigue the kiddos?? Accountable Math Talk Stems for Students. Math by Tori. This year I will be starting "Station Activities" in my math classes (Geometry, Precalc and Math for College Readiness).

Math by Tori

Two of them will be set out for each class each week. Students will take turns working on them during the week. Most, but not all, of them will have accompanying worksheets. This activity is to review the properties of quadrilaterals. It consists of the orange paper, which has 7 quadrilaterals listed, and the business cards, which have the properties printed on them. I found this idea on Pinterest. Here's one that has an inner circle. In this example, I decided to include 3 incorrect answers. Another Pinterest idea...the other side of the chip says "add"... Below is the half-sheet worksheet to go with this station. These are soap containers from Walmart. I will hand these out as students arrive and have them call out what is on their card and the simplified number. Students get one when they come to class.
