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: A ten-strip stands for ten actual objects; five is the strip count.

Next teaching for this question: Audit a different strip, then show two strips are twenty objects.

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: Five tens are fifty; fifty and eight make fifty-eight.

Next teaching for this question: Connect three verified strips and four singles to thirty-four using actual values before a new larger sample.

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: Four tens and eighteen ones, or forty and eighteen; remove the original fifth strip as ten singles replace it.

Next teaching for this question: On a new twenty-four model, remove one strip when its ten singles arrive.

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: Forty plus eighteen equals fifty-eight; member matching shows the original whole is preserved.

Next teaching for this question: Use the same new twenty-four members before/after exchange and verify no duplicate representation.

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.
