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 bundle interpretation. First card: 508 labels. Second card: 580 labels. Third card: 805 labels. All three count the same kind of label; these are supplied counts, not actual stock or money. The supplied alternative first-card model is 4 hundreds, 10 tens and 8 ones. One hundred has the value of ten tens; one ten has the value of ten ones. A helper says: “508 means five hundreds and eight tens.” Use the whole values to represent, compare or order them. Own responses remain open.

D-later-Q1

Use the complete supplied alternative first-card model to find and represent its whole quantity. Explain why its grouping keeps that value.

Criterion

The full model [4, 10, 8] gives 508; ten of its tens replace one hundred without adding or losing value. A valid complete equivalent model is accepted.

After-own staff possibility

4 hundreds + 10 tens + 8 ones = 400 + 100 + 8 = 508; 508 = 5 hundreds + 0 tens + 8 ones = 500 + 0 + 8.

Teach this relationship, check actual opportunity and receive own words before staff models. Later requires a real teaching interval, not a day label.

D-later-Q2

Compare the first and second full quantities. Which is greater? Give a place-value reason.

Criterion

Correctly compares 508 and 580, reporting 580 as greater and explaining the highest place where their values differ.

After-own staff possibility

580 is greater; 508 = 5 hundreds + 0 tens + 8 ones = 500 + 0 + 8. 580 = 5 hundreds + 8 tens + 0 ones = 500 + 80 + 0.

Teach this relationship, check actual opportunity and receive own words before staff models. Later requires a real teaching interval, not a day label.

D-later-Q3

Order all three stated quantities from least to greatest and show a checking reason.

Criterion

Orders 508, 580, 805 using full values, with a place-value or correctly placed number-line check; units remain labels.

After-own staff possibility

508, 580, 805; 508 = 5 hundreds + 0 tens + 8 ones = 500 + 0 + 8. 580 = 5 hundreds + 8 tens + 0 ones = 500 + 80 + 0. 805 = 8 hundreds + 0 tens + 5 ones = 800 + 0 + 5.

Teach this relationship, check actual opportunity and receive own words before staff models. Later requires a real teaching interval, not a day label.

D-later-Q4

Is the supplied helper claim supported? Explain the actual value of the relevant places or groups.

Criterion

Rejects the actual helper claim and recovers 508 from all stated groups; the numeral/model place values, including the zero, support the explanation.

After-own staff possibility

508 means 5 hundreds,0 tens,8 ones=500+0+8. Five hundreds and 8 tens would be 580. The alternative 4 hundreds+10 tens+8 ones also gives 508.

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.
