Session 08 — Budgeting: micro-enterprise and private individual tracks

Course: CALM (PED0770). Topic: CALM-RC-03. ~75 min.

Package: semester_ready\packages\CALM-RC-03\ (flagship).

Spreadsheet optional; paper ledger required as equal.

Two tracks: water/hygiene kiosk and private individual (Jordan). Not financial advice.

Official outcomes / topics

• CALM-R4: knowledge of and commitment to personal financial goals — as a plan that balances or honestly doesn’t.
• CALM-R5: implications of independent/interdependent living — Jordan contributes $120 groceries (interdependent); kiosk is a classroom enterprise, not a lease.
• CALM-R3: aspirations vs resources — if leftover is negative, the aspiration shrinks.
• Canon: income, expenses, budgets, roommates/housing later; this week = one-month model.

Learning targets

1. Complete one monthly budget (Track E or Track P) with given numbers that foot (income − expenses = leftover).
2. Label fixed vs variable; surplus vs deficit.
3. Apply one wellbeing constraint from sessions 03–04 (hours).

Prerequisites

Session 07 matrix. Calculators. Optional laptop.

Diagnostic / retrieval

“If expenses exceed income, the leftover is _____.” Negative / deficit. Not “you failed as a person.”

Instruction

Identity: Income − expenses = leftover. Leftover can fund saving or a want; deficit requires a cut or more income (Jordan’s Saturday is the only extra-income lever we have, and it costs wellbeing).

Track P (Jordan given):

Income 774.

Fixed-ish: bus 71, phone 45, grocery contribution 120.

Variable: lunches 60 packed or 180 café.

Optional want: headphones 90.

Packed, no headphones: 774 − 71 − 45 − 120 − 60 = 478.

Café + headphones: 774 − 71 − 45 − 120 − 180 − 90 = 268.

Track E (kiosk given):

Start cash 800 (classroom grant). Month-1 cash out: table 40, cards 25, 100 soaps × 1.80 = 180, 80 waters × 0.90 = 72.

Outflow = 40+25+180+72 = 317. Cash left before sales = 800 − 317 = 483.

Sales teaching case: 40 soaps × 3.00 = 120; 40 waters × 1.50 = 60; revenue 180.

Cash after sales = 483 + 180 = 663.

Unsold: 60 soaps + 40 waters still on the table — not profit until sold. Gross margin on sold soaps: 3.00 − 1.80 = 1.20 × 40 = 48; waters 1.50 − 0.90 = 0.60 × 40 = 24; product margin 72 before table/cards. Table+cards 65 eat most of that: 72 − 65 = 7 on this volume — honest thin margin.

Wellbeing constraint: do not schedule Jordan Friday 16:00–21:00 at the kiosk; that is the grocery block.

Independent living (R5 light): $120 to household is interdependent. We do not assign a real rent search this week.

CALM-VIS-08-P	After retrieval	80 s	Jordan T-account	774−71−45−120−60=478	Check arithmetic
CALM-VIS-08-E	Minute 22	90 s	Kiosk flow 800→317→483→+180=663	Unsold stock is not cash profit	Don’t treat 663 as “earnings”
CALM-VIS-08-MARGIN	Minute 38	50 s	72 − 65 = 7	“Thin is allowed if honest”	No fake 400% markup

Modelling / worked examples

Show packed 478 on the board with each subtraction. Then kiosk 317 outflow. Then sold 40/40. Then unsold inventory cost: 60×1.80 + 40×0.90 = 108 + 36 = 144 still tied up. Students who call 663 “profit” are corrected.

Paper ledger columns: date, in, out, note, running. Spreadsheet: same columns; formula =C2-D2 on running — optional.

Guided practice + answers

Half the class Track P, half Track E, then swap numbers in the last 8 minutes so everyone sees both.

Track P check: café no headphones leftover = 774 − 71 − 45 − 120 − 180 = 358.

Track E check: outflow 317; if zero sales, cash 483 and inventory on hand.

Independent practice

• FOUNDATION: Copy Jordan packed budget; circle leftover 478.
• CORE: Produce either track with all lines and leftover.
• PROFICIENT: Both tracks on one page; one wellbeing constraint sentence.
• ADVANCED: Shock: zero kiosk sales or Jordan loses 4 job hours (4×15=60 → income 714). Rebalance.

Project connection

This is Milestone 1 budget. Attach to Section C. AI disclosure if formulas were generated.

Checks for understanding

“Is 663 profit?” No. “Can leftover be 478 and still miss a sleep goal?” Yes — money ≠ wellness.

Misconceptions

Wrong	Repair
“Revenue = profit.”	Subtract costs; unsold stock.
“Spreadsheet is mandatory.”	Paper is equal.
“Classroom kiosk is a real CRA business.”	Scenario.
“I have to use my paystub.”	Given 774.

AI Tutor prompts and safeguarding boundaries

Allowed: “Check 40+25+180+72.” “Explain unsold inventory.”

Forbidden: live payroll; opening a real store; “best bank account in Alberta.” Crisis → humans.

Human-tutor handoff

Dyscalculia: fewer lines, same identity. Scribe OK. Shame about money: Track E only.

Exit ticket

Leftover for packed Jordan? 478. Kiosk outflow? 317. One sentence: unsold goods are not profit.

Homework

Finish the chosen ledger. No real account numbers. Optional spreadsheet screenshot without a real bank login visible.

Teacher guidance

Accept paper. If Excel is used, no macros from random web. Do not collect real paystubs. HCS still not copied if someone asks about “working the kiosk safely” — Chem safety card + school rules only.

Materials

Ledger paper; optional sheet file with empty formulas; given-number card.

Preparation

Disable any “link your bank” demo. Write 478, 317, 663, 7 on a hidden answer card.

Timing

Min	Move
0–6	Deficit is a number
6–22	Track P model 478 / 268
22–42	Track E model 317 / 663 / margin 7
42–62	Independent (paper or sheet)
62–70	Swap tracks / shock teaser
70–75	Exit
