Demos

אלון מראה לנועם את כל מה שיש כאן: השולחן, המחברות, הלוח, התצוגות, החדרים והמורים - ומה הוא יודע לעשות, מגרף שנבנה מול העיניים ועד הבה נגילה בגיטרה.

AlonModern classroom

Bella trains Noam, a new agent, on the software itself: verifying callers, privacy, booking and referrals - then three practice calls, from a calm customer to one who shouts.

BellaModern classroom

Noam asks Alon to search the web for 5-unit maths exams. The search runs live on the board, Noam opens the first result - and they start on question 1 together.

AlonModern classroom

Noam is stuck on a quadratic equation. He writes his working on the board with the "Formula" button, adds a note and an arrow, and asks "can you check it?" - Alon reads what he wrote, finds the forgotten minus, and Noam checks it himself: as a graph too.

AlonModern classroom

Noam attaches exam 35582 and gets stuck on question 1. Completing the square, a tangent to a circle, "wait, I didn't get it" - and in the end he solves it himself.

AlonModern classroom

Bella notices Noam is lost in division. On the board, step by step: 735 divided by 5 - and then Noam picks what comes next.

BellaModern classroom

Berthold, in the classic classroom: 358 times 38 - a row per digit, a zero that shifts, carries crossed out, and then the sum.

BertholdClassic classroom

Eti, in the classic classroom: addition with two carries and subtraction borrowing from the neighbor - and Noam answers the last digit of each one himself.

EtiClassic classroom

Yoni and Noam take on the times table: half of it gone thanks to order, the nines trick, the squares on the diagonal - until only ten facts are left, and 7 times 8 falls to 5, 6, 7, 8.

YoniModern classroom

Alon shows why you do the same to both sides: 3x + 5 = 20 as a balance - take five from each side, divide by three, and Noam finds x himself.

AlonModern classroom

Berthold, in the lecture hall: a point travels the unit circle - cosine is how far right, sine how far up - and Noam reads sin 90 off the drawing.

BertholdAuditorium

Alon and Noam study a function by the checklist: domain, intercepts, derivative, the rise-and-fall table - and only then draw it. The minimum sits right on the axis.

AlonModern classroom

Alon, in the space classroom: the derivative is the tangent's slope - Noam finds it is 2x - and the integral is the area underneath, from rectangles to eight thirds. Then how the two connect.

AlonSpace classroom

Eti, in the classic classroom: arithmetic and geometric sequences in one table - until the geometric one runs away - the hundredth term without counting, and young Gauss's trick.

EtiClassic classroom

Bella and Noam count the ways: a tree of two coin tosses, then why seven wins with two dice - six ways out of thirty-six.

BellaModern classroom

Berthold, in the lecture hall: two vectors on the graph, adding head to tail, Noam finds the length with Pythagoras - and multiplying by a number stretches it.

BertholdAuditorium

Alon, in the lecture hall: row times column - Noam does the second row - and the arrow on the graph turns a quarter turn. That's how characters move in video games.

AlonAuditorium

Berthold, in the lecture hall: the area under x squared, in rectangles from above and below - Noam suggests thinner slices, and the two sums meet at a third. The Riemann integral, from the drawing.

BertholdAuditorium

Noam added a half and a third and got two fifths. Eti shows with pizzas why that can't be - and how cutting into sixths solves it. Then Noam adds a third and a quarter himself.

EtiClassic classroom

An age problem Noam is stuck on: Bella draws it as bars - x, three times as much, and ten years on - and the drawing becomes an equation. Noam reads the answer off it.

BellaModern classroom

Noam wrote "I live here for five years" - word for word from Hebrew. Eti, in the classic classroom, shows the tense Hebrew doesn't have: the present perfect, an arrow from the past to now, for and since. And Noam builds a sentence of his own.

EtiClassic classroom

Time travel? Berthold, in the space classroom: Einstein's twin paradox, the gamma curve shooting up near the speed of light - Noam works out his brother comes back five years younger - and the GPS in your phone that corrects for it every day.

BertholdSpace classroom

Alon, in the space classroom: how much Noam would weigh on Mars - he works it out himself - and the same jump on Earth, Mars and the Moon: three parabolas, and on the Moon he floats for almost four seconds.

AlonSpace classroom

Eti, in the lecture hall: the secret of the black keys - C is always left of the pair - the scale from C to C, then a children's song: Eti sings the first line and Noam plays it himself on the board's keys - one note slips, and she hears exactly which.

EtiAuditorium

Alon, in the classic classroom: Noam bought a guitar and can't hold a chord. E minor with two fingers - Noam strums it himself on the board's neck, and Alon hears exactly which string rang open - then A minor, and switching between them like in a song.

AlonClassic classroom

Berthold, in the modern classroom: three opening rules, then a game - and Noam falls for chess's famous trap. One move back, Noam sees the threat on f7 and guards it, and the rule: don't bring the queen out too early.

BertholdModern classroom

Berthold takes Noam back in time: the partition vote and the dancing in the streets, the declaration in Ben-Gurion's voice, the war in the window - and the Green Line.

BertholdModern classroom

The evening before the Passover Seder, Berthold tells Noam the story: the slavery, Moses, the ten plagues, that night and the sea - and why it is told anew every year.
