Word scramble
Unscramble the letters and write each key term on the line.
1
UITPN, SROPCSE, UTPUOT
Plan before coding: read the problem, list what is input, what must be calculated or decided, and what is output. Then pick variables and spot repeats and decisions.
2
RWFAOCHLT
A diagram that solves a problem using symbols for start, input, process, decision, output and stop, joined by arrows. Label each decision Yes or No and test every path to Stop.
3
EADMN NA HMALRIGTO
Find the part that must change for the new requirement, change only that part, then re-trace the algorithm to check the rest still works.
4
MODMNCA DWOR
The exam word that tells you what to write: state the purpose, describe the processes, identify the error, suggest the correction, each in precise terms.
5
PEPECSARU WEDKYSOR
Cambridge pseudocode writes keywords like IF, FOR and WHILE in capitals and indents the lines inside each structure, so the code is easy to read.
6
ADELRCE ECROS : ENERGTI
Creates a variable called Score with a stated data type. Types: INTEGER, REAL, STRING, CHAR, BOOLEAN. Pick a meaningful name.
7
LOTTA ← 0
The ← arrow stores the value on its right in the variable on its left. ______ sets Total to 0. A new assignment replaces the old value. It is not the same as = used to compare.
8
TIUNP NAD UTPUTO
INPUT stores a value from the user in a variable, e.g. INPUT Number. OUTPUT shows a message or value on screen, e.g. OUTPUT "Total is ", Total. Prompt first so users know what to enter.

1UITPN, SROPCSE, UTPUOT → Input, Process, Output — Plan before coding: read the problem, list what is input, what must be calculated or decided, and what is output. Then pick variables and spot repeats and decisions.
2RWFAOCHLT → flowchart — A diagram that solves a problem using symbols for start, input, process, decision, output and stop, joined by arrows. Label each decision Yes or No and test every path to Stop.
3EADMN NA HMALRIGTO → amend an algorithm — Find the part that must change for the new requirement, change only that part, then re-trace the algorithm to check the rest still works.
4MODMNCA DWOR → command word — The exam word that tells you what to write: state the purpose, describe the processes, identify the error, suggest the correction, each in precise terms.
5PEPECSARU WEDKYSOR → UPPERCASE keywords — Cambridge pseudocode writes keywords like IF, FOR and WHILE in capitals and indents the lines inside each structure, so the code is easy to read.
6ADELRCE ECROS : ENERGTI → DECLARE Score : INTEGER — Creates a variable called Score with a stated data type. Types: INTEGER, REAL, STRING, CHAR, BOOLEAN. Pick a meaningful name.
7LOTTA ← 0 → Total ← 0 — The ← arrow stores the value on its right in the variable on its left. Total ← 0 sets Total to 0. A new assignment replaces the old value. It is not the same as = used to compare.
8TIUNP NAD UTPUTO → INPUT and OUTPUT — INPUT stores a value from the user in a variable, e.g. INPUT Number. OUTPUT shows a message or value on screen, e.g. OUTPUT "Total is ", Total. Prompt first so users know what to enter.
