The programs to trace

Directions: Trace each program line by line without a computer. Keep a note of every variable as it changes, then write exactly what the program prints or the final value.

1 What is printed?
1 mark = 58
2 if mark >= 90:
3 print("gold")
4 elif mark >= 70:
5 print("silver")
6 elif mark >= 50:
7 print("bronze")
8 else:
9 print("keep practicing")
2 What is printed?
1 nums = [8, 16, 19, 3, 12, 17]
2 total = 0
3 for n in nums:
4 if n > 8:
5 total += n
6 print(total)
3 What is printed?
1 def bigger(a, b):
2 if a > b:
3 return a
4 return b
5 print(bigger(3, 14) * 3)
4 What is printed?
1 age = 7
2 height = 126
3 if age >= 8 or height >= 134:
4 print("ride")
6 print("wait")
5 What is printed?
1 total = 0
2 for i in range(1, 6):
3 if i % 2 == 0:
4 total += i
5 print(total)
6 What is big at the end?
1 a = 15
2 b = 16
3 if a > b:
4 big = a
6 big = b

What your child practices

Your child builds careful code tracing. The skill is “Conditions”: use if/else to respond to situations.

How to use it

Work through the first program together, one line or arrow at a time. Then let your child work through the rest, showing their thinking on the page. It is one of the easier sheets for Grade 7, good as a warm-up or a first look at the skill.

An answer key comes with it as a separate page that grown-ups download after signing in.

Tip for grown-ups: Have your child write each variable's value beside its line as they trace.

Done on paper? A grown-up can record it on the child's page in PlayOwl; downloading alone doesn't count as finished.
