Use these short texts in the teacher sequence. They are invented SubjectNest examples, not accounts of an actual exhibition, community, accessible route or child. Read aloud where helpful; independent reading must be observed separately.
Text A · an invitation
“Come and explore our little paper exhibit. Choose a book cart, maker shelf, game display or garden model. You can look, point, ask or pass. The rail is a model from 0 to 1. It does not tell you how far to walk.”
Text B · instructions for a model visitor
“Start at 0 on the paper rail. Put a broad marker at 0.30. Look for the next card at 0.65. Ask the maker what the numbers mean. If a label is unclear, point to it or say which step needs a change.”
Text C · how the model works
“The left end of the strip is 0 and the right end is 1 whole. Ten equal spaces show tenths. A hundred equal spaces can show hundredths. The marks 0.3 and 0.30 have the same position because three tenths is thirty hundredths. A dot at 0.65 sits halfway between 0.6 and 0.7 on this evenly divided strip. These are number positions, not measured walking distances.”
Text D · a visitor's opinion
“I liked the wide labels because I could find the first card quickly. I wanted the maker to explain why the marker sat there. My view might differ from another visitor's.”
Source questions: Text A invites; B orders actions; C explains a mathematical model; D reports one fictional opinion. A label copied from D is not independent evidence that a real visitor liked it. A real visitor's feedback can be recorded only with consent and an exact note. A model does not establish physical access, and fictional routes must never be used as school evacuation instructions.
Equal-whole model facts for Week 4
Use five equal-size paper panels as one whole and a ten-part strip of the same total length. Marking two of five equal panels corresponds to four of ten equal parts: 2/5 = 4/10 = 0.4 = 0.40. Marking three of five corresponds to six of ten: 3/5 = 6/10 = 0.6 = 0.60. Marking four of five corresponds to eight of ten: 4/5 = 8/10 = 0.8 = 0.80. These equivalences depend on keeping the whole fixed. Five uneven panels do not show fifths, and a larger number of shaded pieces from a different-size whole does not prove a greater share.
