Complete source
Original fictional label numbers: 507, 570, 750. Chosen amount to represent: 507. Two
pretend card groups contain 38 and 27 cards. A separate pretend project needs 73 labels
and has 29 ready. These are supplied mathematical quantities, not actual stock, price,
creation or a child result. All quantities can be read aloud; no object handling is required.

“Try your own way. You can pause.” Point, draw, say, sign, type, use familiar AAC or direct
an adult to record exactly your choice. An adult may read every source word/question.
Mathematical hints and calculated answers are separately named. Private, untimed
participation and wanted support are welcome; writing/handling is not required.
Put 507, 570, 750 in numerical order. Show or direct a labelled number
line and explain one comparison.
