Word scramble
Unscramble the letters and write each key term on the line.
1
EETAINPRG TPANTER
Same steps that appear again and again. Replace them with one loop to make the algorithm shorter, with the same result.
2
EFNIITNI OPLO
A loop that never stops because its stopping condition can never become true. Something inside the loop, like a counter, must change to work towards the condition.
3
EST UNTOC OT 0
Makes a counter. ______ before the loop, ADD 1 TO count inside the loop each time it repeats, then SHOW count after the loop.
4
ERTPEA INLUT NOTCU = 5
A loop that keeps repeating its steps until the counter reaches the chosen number, 5. The counter must change inside the loop, or the loop never stops.
5
GKCIARTN BLATE
A table with a column for each variable and a row for each step or repeat. It shows how the values change, and the first row holds the starting values.
6
RTCAE
To ______ an algorithm, pick starting values, follow each step in order, write down how the values change, and say what it shows at the end.
7
ESPPURO
What the whole algorithm achieves. Follow the steps, check what it SHOWS and read the variable names for clues, then say it in one sentence.
8
ORTLWHAFC
A diagram that uses an oval for start and end, a rectangle for a step and a diamond for a yes or no question, all joined by arrows that show the order.

1EETAINPRG TPANTER → repeating pattern — Same steps that appear again and again. Replace them with one loop to make the algorithm shorter, with the same result.
2EFNIITNI OPLO → infinite loop — A loop that never stops because its stopping condition can never become true. Something inside the loop, like a counter, must change to work towards the condition.
3EST UNTOC OT 0 → SET count TO 0 — Makes a counter. Set count to 0 before the loop, ADD 1 TO count inside the loop each time it repeats, then SHOW count after the loop.
4ERTPEA INLUT NOTCU = 5 → REPEAT UNTIL count = 5 — A loop that keeps repeating its steps until the counter reaches the chosen number, 5. The counter must change inside the loop, or the loop never stops.
5GKCIARTN BLATE → tracking table — A table with a column for each variable and a row for each step or repeat. It shows how the values change, and the first row holds the starting values.
6RTCAE → trace — To trace an algorithm, pick starting values, follow each step in order, write down how the values change, and say what it shows at the end.
7ESPPURO → purpose — What the whole algorithm achieves. Follow the steps, check what it SHOWS and read the variable names for clues, then say it in one sentence.
8ORTLWHAFC → flowchart — A diagram that uses an oval for start and end, a rectangle for a step and a diamond for a yes or no question, all joined by arrows that show the order.
