Most weak lesson plans don't fall apart because of a bad activity — they fall apart because the objective was never really an objective. "Students will learn about the water cycle" describes a topic. It doesn't describe anything you could check for, walk around the room and observe, or put on an exit ticket. A real objective is a single sentence you could hand to another teacher and they'd know exactly what to look for by the end of the period.
Here's how to write one that actually works — the framework, the verbs that make it measurable, and the ones to avoid.

The ABCD Framework
Instructional designers use a simple four-part structure to check whether an objective is complete: Audience, Behavior, Condition, Degree.
- Audience — who's doing the learning. Usually just "students," but can be more specific ("small group readers," "the class").
- Behavior — the observable action, expressed as a measurable verb (more on this below).
- Condition — the circumstances or tools available while doing it ("given a map," "using a calculator," "in a group of three").
- Degree — how well, how much, or how accurately ("with 80% accuracy," "in at least two sentences," "correctly").
You don't need all four in every objective — Condition and Degree are often optional — but Audience and Behavior are non-negotiable. Behavior is where most objectives quietly fail.
Bloom's Taxonomy Action Verbs
The "behavior" part of the objective lives or dies on the verb. Bloom's Taxonomy groups verbs into six levels of thinking, from simple recall up to creating something new. Picking a verb from the right level is what makes an objective both measurable and appropriately challenging for where students actually are.
| Level | What it asks for | Example verbs |
|---|---|---|
| Remember | Recall facts | define, list, label, name, identify |
| Understand | Explain ideas | summarize, describe, classify, explain |
| Apply | Use in new situations | solve, demonstrate, calculate, use |
| Analyze | Draw connections | compare, contrast, categorize, examine |
| Evaluate | Justify a stance | argue, defend, critique, judge |
| Create | Produce something new | design, compose, construct, generate |
A quick sanity check: every verb in that table describes something a student does, not something that happens inside their head where you can't see it. That's the entire point.
Verbs to Avoid
These show up constantly in draft objectives, and every one of them is a sign the objective isn't finished yet — because none of them describe anything observable.
- Understand — how would you check? Replace with "explain," "summarize," or "identify."
- Know — same problem. Replace with "state," "list," or "define."
- Learn — describes the process, not the outcome. Replace with what they'll be able to do once they've learned it.
- Appreciate — common in art and music objectives, but unmeasurable. Replace with "describe why," "identify examples of," or "compare."
- Be aware of / be familiar with — vague enough to mean almost anything. Replace with a specific, checkable action.
Examples by Grade and Subject
Elementary (K–5)
Middle School (6–8)
High School (9–12)
Common Mistakes
- Writing the activity instead of the outcome. "Students will complete a worksheet on fractions" describes what they'll do during the lesson, not what they'll be able to do afterward. The worksheet is how you'll practice the objective, not the objective itself.
- Objectives that are really just the standard, copied verbatim. Standards are often written broadly enough to cover a whole unit. A daily objective should be the specific slice of that standard you're teaching today.
- Objectives too big for one lesson. If it would genuinely take three days to teach and assess, it's a unit goal, not a daily objective — break it down.
- No way to check it. If you can't picture the exit ticket or quick check that would confirm students hit the objective, the objective probably isn't specific enough yet.
The formula, one more time
Students will be able to [measurable verb] + [specific content] + [condition or degree, if useful]. Write this sentence first, before anything else in the plan — the rest of the lesson (materials, activities, assessment) should all trace back to making that one sentence true by the end of class.
