# D-first neutral own job ## Id D-first ## Family D ## Title D-first neutral own job ## Source Fictional label quantities: First bundle comparison. First card: 507 labels. Second card: 570 labels. Third card: 470 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 7 ones. One hundred has the value of ten tens; one ten has the value of ten ones. A helper says: “The first alternative has value 417.” Use the whole values to represent, compare or order them. Own responses remain open. ## Source data ### Source Fictional label quantities: First bundle comparison. First card: 507 labels. Second card: 570 labels. Third card: 470 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 7 ones. One hundred has the value of ten tens; one ten has the value of ten ones. A helper says: “The first alternative has value 417.” Use the whole values to represent, compare or order them. Own responses remain open. ### Values - 507 - 570 - 470 ### Alternative first parts - 4 - 10 - 7 ### Claim The first alternative has value 417. ### Models - 507 = 5 hundreds + 0 tens + 7 ones = 500 + 0 + 7. - 570 = 5 hundreds + 7 tens + 0 ones = 500 + 70 + 0. - 470 = 4 hundreds + 7 tens + 0 ones = 400 + 70 + 0. ### Ordered - 470 - 507 - 570 ## Questions #### Id D-first-Q1 #### Prompt 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, 7] gives 507; ten of its tens replace one hundred without adding or losing value. A valid complete equivalent model is accepted. #### Worked possible response 4 hundreds + 10 tens + 7 ones = 400 + 100 + 7 = 507; 507 = 5 hundreds + 0 tens + 7 ones = 500 + 0 + 7. #### Own response #### Next id N13 #### Eligibility Teach this relationship, check actual opportunity and receive own words before staff models. Later requires a real teaching interval, not a day label. #### Id D-first-Q2 #### Prompt Compare the first and second full quantities. Which is greater? Give a place-value reason. #### Criterion Correctly compares 507 and 570, reporting 570 as greater and explaining the highest place where their values differ. #### Worked possible response 570 is greater; 507 = 5 hundreds + 0 tens + 7 ones = 500 + 0 + 7. 570 = 5 hundreds + 7 tens + 0 ones = 500 + 70 + 0. #### Own response #### Next id N14 #### Eligibility Teach this relationship, check actual opportunity and receive own words before staff models. Later requires a real teaching interval, not a day label. #### Id D-first-Q3 #### Prompt Order all three stated quantities from least to greatest and show a checking reason. #### Criterion Orders 470, 507, 570 using full values, with a place-value or correctly placed number-line check; units remain labels. #### Worked possible response 470, 507, 570; 470 = 4 hundreds + 7 tens + 0 ones = 400 + 70 + 0. 507 = 5 hundreds + 0 tens + 7 ones = 500 + 0 + 7. 570 = 5 hundreds + 7 tens + 0 ones = 500 + 70 + 0. #### Own response #### Next id N15 #### Eligibility Teach this relationship, check actual opportunity and receive own words before staff models. Later requires a real teaching interval, not a day label. #### Id D-first-Q4 #### Prompt Is the supplied helper claim supported? Explain the actual value of the relevant places or groups. #### Criterion Rejects the actual helper claim and recovers 507 from all stated groups; the numeral/model place values, including the zero, support the explanation. #### Worked possible response 4 hundreds+10 tens+7 ones =400+100+7=507, not 417. #### Own response #### Next id N16 #### Eligibility Teach this relationship, check actual opportunity and receive own words before staff models. Later requires a real teaching interval, not a day label. ## Own routes - Whole neutral source initially closed in native same-page details; no criterion/worked/teacher content in that disclosure. - Four genuine empty own fields matching these four exact prompts; no preset answer or required typed completion. - Matched V13–20 paper/full alternative repeats this exact whole neutral source and four prompts, with four genuinely empty response regions. Ordinary seven-heading Desk paper is a different task. ## Staff handoffs - matching complete neutral source - matching own four-response page - matched held SVG - matched full alternative - N13 complete next teaching page - N14 complete next teaching page - N15 complete next teaching page - N16 complete next teaching page ## Eligibility 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. ## Held roles Answers/criteria/fullNEXT/adult models remain staff-only. Complete source facts/labels and supplied helper claim are neutral input, not prefilled child responses. ## Grant Original © NeuroForgeIO Pty Ltd 2026, SubjectNest, CC BY4.0.
