The programs to trace

Directions: Read each program from top to bottom, one block at a time. Keep track of every box (variable) as it changes, then write the answer.

1 What does Olly say?
set count to 0 for each n in [10, 1, 8, 7, 5] if n > 5 then change count by 1 say count
2 What does Olly say?
set total to 0 for each n in [2, 9, 5, 1] change total by n say total
3 What does Olly say?
set count to 0 for each n in [6, 10, 8, 10, 4] if n > 4 then change count by 1 say count
4 What does Olly say?
set total to 0 for each n in [6, 1, 8, 2] change total by n say total
5 What does Olly say?
set count to 0 for each n in [8, 2, 8, 4, 6] if n > 4 then change count by 1 say count

What your child practices

Your child builds careful code tracing. The skill is “Loops”: use repetition to shorten programs.

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 5, 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.
