C-first neutral own job · staff judgement
Actual source reading may familiarise the paper scene neutrally. Record actual instruction/support and teach before using a component. Later is a new offer after a real teaching interval; no universal familiarity or progress is claimed.
Whole neutral source
Fictional label quantities: First archive quantities. First card: 304 labels. Second card: 340 labels. Third card: 403 labels. All three count the same kind of label; these are supplied counts, not actual stock or money. A helper says: “304 and 340 have the same value because their digits are the same.” Use the whole values to represent, compare or order them. Own responses remain open.
C-first-Q1
Represent the first-card quantity with hundreds, tens and ones; name the value of each part.
Criterion
Represents 304 as 3 hundreds, 0 tens, 4 ones; names 300, 0, 4 as their values.
After-own staff possibility
304 = 3 hundreds + 0 tens + 4 ones = 300 + 0 + 4.
Teach this relationship, check actual opportunity and receive own words before staff models. Later requires a real teaching interval, not a day label.
C-first-Q2
Compare the first and second full quantities. Which is greater? Give a place-value reason.
Criterion
Correctly compares 304 and 340, reporting 340 as greater and explaining the highest place where their values differ.
After-own staff possibility
340 is greater; 304 = 3 hundreds + 0 tens + 4 ones = 300 + 0 + 4. 340 = 3 hundreds + 4 tens + 0 ones = 300 + 40 + 0.
Teach this relationship, check actual opportunity and receive own words before staff models. Later requires a real teaching interval, not a day label.
C-first-Q3
Order all three stated quantities from least to greatest and show a checking reason.
Criterion
Orders 304, 340, 403 using full values, with a place-value or correctly placed number-line check; units remain labels.
After-own staff possibility
304, 340, 403; 304 = 3 hundreds + 0 tens + 4 ones = 300 + 0 + 4. 340 = 3 hundreds + 4 tens + 0 ones = 300 + 40 + 0. 403 = 4 hundreds + 0 tens + 3 ones = 400 + 0 + 3.
Teach this relationship, check actual opportunity and receive own words before staff models. Later requires a real teaching interval, not a day label.
C-first-Q4
Is the supplied helper claim supported? Explain the actual value of the relevant places or groups.
Criterion
Rejects equal value from matching digit sets: 304 and 340 assign tens/ones different values and are unequal.
After-own staff possibility
304 and 340 have different place values: 304 = 3 hundreds + 0 tens + 4 ones = 300 + 0 + 4. 340 = 3 hundreds + 4 tens + 0 ones = 300 + 40 + 0.

Answers/criteria/fullNEXT/adult models remain staff-only. Complete source facts/labels and supplied helper claim are neutral input, not prefilled child responses.
