Sample class · Block 2 — Vowel Teams probe

This is what Orthos shows you.

Give a spelling probe, mark it in a few taps, and Orthos turns the misspellings into a class heat map, the exact pattern to teach next, and the resource that teaches it — no Sunday-afternoon color-coding.

Vowel Team Pattern Teach

15 errors across 5 students
The pattern
Students reach for the wrong spelling of a long-vowel sound — "reson" for "reason", "beech" for "beach" — because the vowel team isn't mapped yet.
Try this
Vowel-team sort: put ea / ee / ai side by side, sort 12 words into team columns, then have the student spell each back. The sort does the work.
