C-later 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: Later display quantities. First card: 620 labels. Second card: 602 labels. Third card: 260 labels. All three count the same kind of label; these are supplied counts, not actual stock or money. A helper says: “620 and 602 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-later-Q1
Represent the first-card quantity with hundreds, tens and ones; name the value of each part.
Criterion
Represents 620 as 6 hundreds, 2 tens, 0 ones; names 600, 20, 0 as their values.
After-own staff possibility
620 = 6 hundreds + 2 tens + 0 ones = 600 + 20 + 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-later-Q2
Compare the first and second full quantities. Which is greater? Give a place-value reason.
Criterion
Correctly compares 620 and 602, reporting 620 as greater and explaining the highest place where their values differ.
After-own staff possibility
620 is greater; 620 = 6 hundreds + 2 tens + 0 ones = 600 + 20 + 0. 602 = 6 hundreds + 0 tens + 2 ones = 600 + 0 + 2.
Teach this relationship, check actual opportunity and receive own words before staff models. Later requires a real teaching interval, not a day label.
C-later-Q3
Order all three stated quantities from least to greatest and show a checking reason.
Criterion
Orders 260, 602, 620 using full values, with a place-value or correctly placed number-line check; units remain labels.
After-own staff possibility
260, 602, 620; 260 = 2 hundreds + 6 tens + 0 ones = 200 + 60 + 0. 602 = 6 hundreds + 0 tens + 2 ones = 600 + 0 + 2. 620 = 6 hundreds + 2 tens + 0 ones = 600 + 20 + 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-later-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: 620 and 602 assign tens/ones different values and are unequal.
After-own staff possibility
620 and 602 have different place values: 620 = 6 hundreds + 2 tens + 0 ones = 600 + 20 + 0. 602 = 6 hundreds + 0 tens + 2 ones = 600 + 0 + 2.
Teach this relationship, check actual opportunity and receive own words before staff models. Later requires a real teaching interval, not a day label.
Answers/criteria/fullNEXT/adult models remain staff-only. Complete source facts/labels and supplied helper claim are neutral input, not prefilled child responses.
