Trace the binary search for 42 and colour-code sequence, selection and iteration in the flowchart.

Use the parent guidance on page 2. Print on A4 paper at actual size or fit to printable area, then encourage careful colouring and discussion of the learning topic.

Use the guidance and answer key on page 2. Answer or assessment rubric: On sorted data [3,8,12,17,23,31,42,56], compare with 17, then 31, then find 42. Binary search repeatedly discards half the remaining range. Sequence follows ordered steps; selection chooses a branch; iteration repeats steps while a condition holds.
