Source and own response remain separate. Preserve first thinking and actual support before reading this key into feedback. A correct supplied value is not independent discovery.

Question 1: Unit

Look for in this source: Each full strip represents ten objects, verified from its ten cells. Four is the number of strips, not the value of one strip.

Next teaching for this question: Audit a new strip by touching all ten cells; connect one strip to ten singles.

Later invitation: choose a new complete case after that teaching. Record changed quantity/arrangement and prior familiarity; do not repeat this exact answer until memorised.

Question 2: Whole

Look for in this source: Four tens are forty; forty plus six is forty-six.

Next teaching for this question: Use a new two-tens/five-ones model and distinguish strip count from object values.

Later invitation: choose a new complete case after that teaching. Record changed quantity/arrangement and prior familiarity; do not repeat this exact answer until memorised.

Question 3: Replacement

Look for in this source: Remove one original strip and replace it with ten singles: three tens and sixteen ones, or thirty and sixteen. No old strip plus its singles are simultaneously counted.

Next teaching for this question: In a new thirty-one model, exchange one strip while covering/removing the old strip.

Later invitation: choose a new complete case after that teaching. Record changed quantity/arrangement and prior familiarity; do not repeat this exact answer until memorised.

Question 4: Equality

Look for in this source: Thirty plus sixteen still represents forty-six original objects; the replaced ten is matched once.

Next teaching for this question: Match the same ten members to a strip and its replacement, then recount the new whole without duplication.

Later invitation: choose a new complete case after that teaching. Record changed quantity/arrangement and prior familiarity; do not repeat this exact answer until memorised.
