Capstone checkpoint 3:budget and unit-cost evidence

Objective. Capstone checkpoint 3:budget and unit-cost evidence:apply the stated method to a concrete case,produce the requested evidence,and justify safe,private,and accessible choices.

About 25–50 minutes. The due date is chosen by a parent.

Split across sittings as needed;no timer or required date.Adult approval remains required even for independent work.

Materials: paper, pencil, optional calculator.

Fictional capstone case:four people share a 90-minute meal-and-home-reset event. One needs a seated workspace and one avoids milk; an adult must verify ingredients. The paper budget is$60:reserve$10 for savings, up to$20 for food, $8 for care supplies, $12 for transport, and the rest as buffer. Use paper tools/food by default; no purchases, real guests, or actual care are required. A capstone budget must reconcile the whole$60, not only a recipe's portion cost. Use invented prices and label them as assumptions. Distinguish package cash cost from the amount used. Keep reserves and a buffer visible. “No purchase”remains the real-world rule; the budget is a calculation. A lower sticker price does not justify an unsafe or unsuitable ingredient. Safety and boundaries: All capstone evidence can be paper/simulation. Adult approval/direct supervision for any optional food, heat, sharp-tool, cleaning, or sewing activity. No real care subjects, transactions, public posting, or private household information. Family-only evidence;use fictional details,no faces or private records.No purchases are required.

Worked example

Unscored model for discussion;use the assignment case for your own work.

A fictional meal table might use beans$2.40, tortillas$2.80, vegetables$3.20, and fruit$1.60; the total is checked separately from other budget categories.

Capstone checkpoint 3:budget and unit-cost evidence — evidence and reflection

  1. 1. Build the full$60 category plan from the case and identify its initial buffer.
  2. 2. Price your meal with invented costs at or below 20 and show actual planned food total.
  3. 3. Compare two fictional package sizes using equal units and usable yield.
  4. 4. Explain how unused food allowance affects the overall unassigned amount.
  5. 5. Spiral review — A message demands a password within 5 minutes. What are three safe responses? Spiral review.

Acceptance checks

An adult supervises. This stays in the family. Spending is a simulation, not real money.

For any optional food,adult verifies all ingredients and established allergy needs;avoid cross-contact,no tolerance tests,and use paper food if uncertain.For clothing/cleaning,adult checks sensitivities and labels;no chemical mixing.

All capstone evidence can be paper/simulation. Adult approval/direct supervision for any optional food, heat, sharp-tool, cleaning, or sewing activity. No real care subjects, transactions, public posting, or private household information.

Complete the entire task using paper diagrams,fictional data,empty/inactive tools,and parent-observed explanation.

  • No unsupervised heat,sharp tools,cleaners,or appliances.
  • No raw-meat handling,unsafe food tasting,chemical mixing,flame/smoke experiments,or electrical repair.
  • No real childcare/medical/intimate care,financial transactions,credentials,private records,or public posting.

If this is still shaky. Use this lesson’s worked model to make a three-box process card.Label the goal,one safety/constraint check,and the evidence you would show.Explain it to a parent before trying the main task again.

Optional extra. Change one fictional constraint in this lesson,such as available time,access,ingredient restriction,or pretend cost.Revise one artifact and show what must change and what safety/privacy rule stays fixed.
