Classmates and a shared till

The till is a class agreement, not loot

A shared till is a budget that is not yours. You chip in. An adult watches. Rules say what is M, who writes, what happens when someone does not give, and that W each person carries alone.

With no rules the till is a fight. With rules it is a trip. You are not a bank cashier. You are a member who can do paper.

Ondra takes from the till for lemonade, “I chip in too”. Nela: the rule — the till = entry + a reserve. Lemonade from a pocket. Ondra is in the wrong. The till is not a buffet.

Someone cannot chip in. A teacher handles silence and dignity, not a ranking. Nela does not say it out loud in class.

Rules before a coin

Five points: a ceiling, M lines, a reserve, who writes, what with leftover. With no fifth point, after the trip mood gets stolen.

Does not give: an adult handles that. You do not chase a debt in the corridor. A debt hunt is bullying. A loan into the till from last time still holds: no.

A till record is public in class only as a sum and lines, not as “Ondra gave less”. Riêng tư of the map. A teacher sees names. A noticeboard does not.

Card payments on a trip: a parent or a teacher. Not a classmate’s PIN. Not a QR from a stranger at the station with no name check — Banker can do that. Today: the till ≠ your card.

Nela wants to shorten it to “it will be fine somehow”. Ondra asks what the lesson Classmates and a shared till is for, when a table can do a sum. A sum does not count respect, a PIN, a trap or an envelope. The core is: The till has rules and an adult. It is not a buffet from your folder.

Adults pay the rent. The card, the account and the PIN belong to a parent. A child’s email does not belong here. Pocket-money numbers do not belong on the network. If you break these rules in the lesson “Classmates and a shared till”, you know a word, not the course.

The till: 12×80 = 960 (for practice). Entry 600, a reserve 120, shared food 200. Nela sees it. Ondra’s lemonades 15×20 would eat the reserve. A stop rule.

Leftover 40: return by share, or the next event — a teacher decides in advance. Not “who watched, that one gets it”.

Practice numbers, not a bank statement. Nela has 80 Kč in the want envelope. Ondra pushes a step this lesson can name. When Nela uses the core, either it waits for a parent, or it fits the envelope. If not, anger and a hole are left — proof of pressure, not that the lesson is pointless.

Why this right now

You are in the course Money with Martin, level Planner. You can write numbers in a notebook or a table, but the topic is money and decisions, not Excel formulas. The account, the card and the PIN belong to a parent. A child’s email does not belong here. Do not put pocket-money numbers on the network.

This is not the Sheets with Martin course. A table may help, but the mark of success is a decision, not SUM.

You will know this lesson by one sentence: The till has rules and an adult. It is not a buffet from your folder. When you can say it to a parent or a teacher, you have the core. The rest is practice, not magic.

When it runs out, you will know whose problem it is — the till’s vs. your pocket. With no rules every empty bag is your fault.

If you skip this, the next lesson in level Planner will stand on fog. Five points on paper. Lemonade is a pocket. Debtors’ names are not on the board. It is not a test for marks. It is a safety net, so “Classmates and a shared till” is not only a heading.

Four things you will build from the course

The course has four small projects. You do not have to do them all at once. Today you add only what this lesson can do.

Workshop: five till points

A practice till. Do not write real debtors’ names. It is not a collection.

1. Five points in your own words.

2. One thing that does not belong in the till (W).

3. What you will do when a friend does not give — one sentence: a teacher, not a hunt.

4. The till notebook ≠ your pocket-money notebook.

You count with five points. A bag with no points is Ondra’s lemonade. Lemonade can eat a trip.

Pocket money: Do not mix pocket money with the till in one notebook. Do not write someone else’s amount, a PIN, an IBAN or “how much a classmate gets” next to it. A rule and a practice number are enough — or an honest zero.

Class trip: The trip project: this lesson is the heart. Do not write someone else’s amount, a PIN, an IBAN or “how much a classmate gets” next to it. A rule and a practice number are enough — or an honest zero.

Game shop: A game from the shared till = no, unless it is M and approved. Do not write someone else’s amount, a PIN, an IBAN or “how much a classmate gets” next to it. A rule and a practice number are enough — or an honest zero.

Stall: A stall: a mini-company till has the same five points. Do not write someone else’s amount, a PIN, an IBAN or “how much a classmate gets” next to it. A rule and a practice number are enough — or an honest zero.

Practice: the till, or a pocket?

Where do you reach?

1. Lemonade. The till, or a pocket, when the rule is entry+a reserve?

2. A classmate did not give. Who handles it?

3. Leftover. Why not “who watched”?

4. A board with debtors’ names. Why not?

Now you 💪

Go through three checks. By each one, tick in your head: do I see it, or not?

1. I can say five points.
2. W does not belong in the till with no rule.
3. I do not hunt a debt.

If something is missing, go back to the steps above. It is not a test for marks. It is a safety net, so you go on with certainty, not with a mess.

What to take from this lesson

• The till = rules + an adult.
• Riêng tư of folders.
• Leftover is decided in advance.
• Your card is not the till.
• Têns in the examples (Nela, Ondra) are made up. Do not put your number, email or photo here.
• Next lesson: When you can do this, go to the next lesson in the same level.
