# Thirty participation choices

Pick one, combine them, or ask for a different comfortable route. These are invitations, not ability, diagnosis or fixed-style groups. Adult reading/scribing follows child choices; mathematical hints are recorded separately. Neither touch, movement, speech, handwriting, printing nor a device is required.

## Day 41

- **A · One useful part:** Choose one safe question and two named options; tell why the answer would help.
- **B · Make or direct:** Draw/direct a question card with a one-choice rule and a way to pass.
- **C · Another check:** Test whether a pretend reply fits exactly one category; revise an unclear option.

## Day 42

- **A · One useful part:** Sort the first three MODEL1 replies, retaining the full list and naming your subset.
- **B · Make or direct:** Read/direct all MODEL2 replies into named groups; keep unavailable records separate.
- **C · Another check:** Trace one record ID through list→group to check it was neither lost nor duplicated.

## Day 43

- **A · One useful part:** Make one row then another; include an intended option with zero replies.
- **B · Make or direct:** Create/direct a complete table and source-total check for MODEL2.
- **C · Another check:** Make an equal-symbol display with a key; compare what it and the table show.

## Day 44

- **A · One useful part:** Choose between two claims and point/direct the source evidence.
- **B · Make or direct:** Make one bounded statement plus one question still unknown from MODEL2.
- **C · Another check:** Compare two recorded groups, including a tie; explain why missing replies cannot resolve it.

## Day 45

- **A · One useful part:** Make a three-line data-help sign: question, counts, one careful statement.
- **B · Make or direct:** Create/direct an own table or representation and test one reader question.
- **C · Another check:** Revise one useful feature from actual self/reader use; call untried use a plan.

## Day 46

- **A · One useful part:** Compare305 and350 with named places; use a supplied line before an own choice.
- **B · Make or direct:** Order408,480,804 and draw/direct meaningful line references.
- **C · Another check:** Place990 and1000 on a one-unit strip; explain the new thousand, not an invented three-digit form.

## Day 47

- **A · One useful part:** Show405 in standard form; zero records no tens.
- **B · Make or direct:** Choose236 and direct an actual exchange while preserving total value.
- **C · Another check:** Find a second nonstandard partition and check it independently; no all-partitions quota.

## Day 48

- **A · One useful part:** Use counted broad marks or direction for19+6, explaining the joined quantity.
- **B · Make or direct:** Choose a tens bridge or partition for32−8; label each part.
- **C · Another check:** Compare two methods on another ordinary one/two-digit problem and use the inverse to check.

## Day 49

- **A · One useful part:** Choose needed/ready/more in one fictional project and explain the missing part.
- **B · Make or direct:** Make/direct an own representation and answer with its units for C20.
- **C · Another check:** Change one ordinary quantity, predict which solution changes and actually check it.

## Day 50

- **A · One useful part:** Select one actual ordinary choice and say what helped or what still needs teaching.
- **B · Make or direct:** Use an appropriate unseen full held source with your usual communication and pauses.
- **C · Another check:** After capture, choose a new ordinary next question; keep supported changes separate.

Private, untimed participation, rest and return are welcome. Adapt quantity/range after prerequisite checks and name that scope. Longer responses, polished art and fast facts are not automatically better mathematical evidence.
