The Cold Case

Five problems, chosen so each one leans on a different part of solving. The point is not her score. The point is to hear exactly where her thinking stalls, so the next nine weeks aim at the right thing.

How to run it
  1. Print or send Kelcy's sheet to GoodNotes. She gets the questions and space, nothing else.
  2. Voice memo on. Tell her: "Talk out loud the whole time, even the messy bits. I want to hear you thinking, not just the answer."
  3. No help. This one time, you do not prompt, hint, or rescue, even if she is stuck. If she stalls, "do what you can, talk me through what is making it tricky" and move on. Being stuck is the data.
  4. Let her skip and come back. Note the order she does them in.
  5. Afterwards, listen to the memo with the observation sheet below and mark where each blocker showed up.

Why no help, just this once

Every other week you scaffold hard. Here you deliberately do not, because you are measuring her unaided starting point. You will do the identical no-help run in Week 5 and Week 10, so the three become a clean before, middle, and after.
The six blockers you are listening for

Solving a word problem is a chain. It can snap at any link. These are the six links, what a snap sounds like, and where to push if it is the culprit.

๐Ÿ” 1 ยท Decode
Snaps like

Doesn't work out what is being asked. Grabs every number including irrelevant ones. Answers a different question than the one asked.

Then lean into: read-it-twice, hunt-the-question, spotting the distractor.
๐Ÿ—‚๏ธ 2 ยท Connect
Snaps like

Treats every problem as brand new. Doesn't notice two problems are the same shape. Can't say what "type" it is.

Then lean into: naming case types, "have I seen one like this?", building the journal archive.
๐Ÿงฐ 3 ยท Strategy
Snaps like

Stares, no idea where to start. Doesn't reach for a table or diagram. Tries random operations hoping one works.

Then lean into: Pick Your Gadget, drawing it, working backwards, smaller-case-first.
๐Ÿšช 4 ยท Monitor
Snaps like

Picks a path and never checks it. Doesn't catch a wrong step. Stops one step early and answers half the question.

Then lean into: the Three Knocks, multi-step problems, "did you answer what it asked?"
๐Ÿงฎ 5 ยท Fundamentals
Snaps like

Decodes fine, but the arithmetic is the wall: percentages, fractions, negatives, or rearranging an equation.

Then lean into: shoring up that exact skill in sessions, drop the chilli level until it is solid.
๐Ÿ‘ƒ 6 ยท Evaluate
Snaps like

Writes a number and moves on. Never asks if it is reasonable. Wrong units, or an impossible size, left unchallenged.

Then lean into: the Sniff Test as a hard stop on every single problem.
The five questions, and what each is probing

Kelcy sees only the questions (on her sheet). You see the intent, what to watch for, and the worked answer. Every one has been solved and checked.

Q1๐Ÿ” Decode (with a distractor)๐ŸŒถ๏ธ

Liam is filling a 45 litre fish tank using a bucket. The tank already has 9 litres in it. Each time he tips the bucket in, it adds 4 litres. He started at 3pm. How many bucket-loads until the tank is full?

Watch for: Does she ignore "started at 3pm" (irrelevant)? Does she use the 9 litres already there, or divide 45 by 4 straight away? This is a friendly Tank problem on purpose, so any wobble here is about decoding, not maths.

๐Ÿ”‘ Worked answer

Start 9 L, target 45 L, rate 4 L per bucket. To go: 45 โˆ’ 9 = 36. Buckets: 36 รท 4 = 9. 9 bucket-loads. Check: 9 + 4ร—9 = 45. The 3pm is a red herring.

Q2๐Ÿ—‚๏ธ Connect (same shape, new dress)๐ŸŒถ๏ธ๐ŸŒถ๏ธ

A candle is 20 cm tall when it is lit. It burns down by 3 cm every hour. After how many hours will it be 5 cm tall?

Watch for: Does she notice this is the same shape as Q1 (a start value and a steady rate), just going down instead of up? Recognising the structure across the sign change is the schema skill. If she restarts from scratch with no sense of dรฉjร  vu, that is a Connect snap.

๐Ÿ”‘ Worked answer

Start 20 cm, target 5 cm, dropping 3 cm per hour. To lose: 20 โˆ’ 5 = 15. Hours: 15 รท 3 = 5. 5 hours. Check: 20 โˆ’ 3ร—5 = 5.

Q3๐Ÿงฐ Strategy (no obvious operation)๐ŸŒถ๏ธ๐ŸŒถ๏ธ๐ŸŒถ๏ธ

At a market stall, one large jar of honey costs the same as three small jars. Maya buys two large jars and four small jars and spends $50 in total. How much does one small jar cost?

Watch for: There is no single sum to reach for. Does she find a strategy, swapping everything into "small jars", or a table, or trial and improvement? Flailing with random operations is a Strategy snap. Picking any sensible representation, even slowly, is a win.

๐Ÿ”‘ Worked answer

One large = three small. So two large = six small. Total in small jars: 6 + 4 = 10 small jars = $50, so one small = 50 รท 10 = $5. Small jar $5 (large jar $15). Check: 2ร—15 + 4ร—5 = 30 + 20 = 50.

Q4๐Ÿšช Monitor (multi-step)๐ŸŒถ๏ธ๐ŸŒถ๏ธ

A jacket costs $80. In a sale it is reduced by 25%. At the till, Kelcy also uses a member card that takes a further $5 off. How much does she pay?

Watch for: Two steps, in order: the percentage first, then the flat $5. Does she do both? Does she stop after the 25% and forget the $5? Does she wrongly treat the $5 as another percentage? Stopping early or losing track is a Monitor snap. (A shaky 25% is a Fundamentals note, see Q5.)

๐Ÿ”‘ Worked answer

25% of 80 = 20, so sale price 80 โˆ’ 20 = 60. Then the card: 60 โˆ’ 5 = 55. She pays $55. Common slip: answering $60 (stopped early) or taking 25% off after the $5.

Q5๐Ÿงฎ Fundamentals (decode is easy)๐ŸŒถ๏ธ๐ŸŒถ๏ธ

The perimeter of a rectangle is 30 cm. The length is twice the width. Find the length and the width.

Watch for: The words are simple, so a snap here is almost certainly fundamentals: setting up length = 2 ร— width, using the perimeter, and solving 3 ร— width = 15. If she understands the situation but can't do the algebra, that tells you the wall is earlier skills, not word-problem reading.

๐Ÿ”‘ Worked answer

Perimeter = 2 ร— (length + width) = 30, so length + width = 15. Length = 2 ร— width, so 2w + w = 15, giving 3w = 15, w = 5. Width 5 cm, length 10 cm. Check: 2 ร— (10 + 5) = 30, and 10 is twice 5.

๐Ÿ‘ƒ The seventh thing: Evaluate, across all five

Evaluate doesn't get its own question, you assess it everywhere. On each one, does she pause and check the answer makes sense, or write a number and move on? Mark it in the last column of the sheet.
