Unit Planning With Backwards Design: Starting With the End Makes Everything Else Easier

Grant Wiggins and Jay McTighe introduced backwards design in their 1998 book "Understanding by Design," and it's become one of the most widely cited frameworks in curriculum development. The idea is disarmingly simple: start with the end, then plan backward to the beginning.

Most teachers plan units the other way around — they start with activities and resources they like, add assessments at the end, and hope the objectives emerge from the accumulation. Backwards design reverses this and, in doing so, produces more coherent and more effective units.

Here's how to actually do it.

Stage 1: Identify Desired Results

The first question in backwards design is not "what will we do?" It's "what do we want students to know, understand, and be able to do by the end of this unit?"

This question has three levels:

Transfer goals — the long-term, transferable understandings that extend beyond this unit. Students will be able to read primary sources critically and evaluate historical evidence. Students will apply proportional reasoning to real-world contexts. These don't get fully assessed in any single unit; they're the targets you keep aiming at.

Understandings — the big ideas of this unit. These are stated as full sentences, often framed as insights that might be surprising or non-obvious. "The same event can be interpreted very differently depending on the perspective of the source." "Mathematical models are always simplifications that lose something."

Knowledge and skills — the specific content and procedures students need to master. The vocabulary, the facts, the technical skills that make the understandings accessible.

Most teachers jump straight to the third level. Backwards design starts at the first, which keeps the unit organized around meaning rather than just coverage.

Stage 2: Determine Acceptable Evidence

The second question: how will you know students have achieved the desired results?

This means designing your assessments before you design your instruction. What performance would demonstrate that a student truly understands the big ideas? What would a sophisticated transfer look like versus a surface application?

Wiggins and McTighe advocate for performance tasks — assessments that require students to apply their understanding in a meaningful, real-world context. Not just "answer these comprehension questions" but "write a letter from the perspective of a citizen during this historical moment" or "design an experiment to test this hypothesis" or "create a presentation explaining this concept to an unfamiliar audience."

Performance tasks reveal the depth of understanding in a way that recall questions don't. A student who can answer factual questions about the French Revolution hasn't necessarily understood it. A student who can construct a coherent argument about its causes from primary sources has.

Stage 3: Plan Learning Experiences and Instruction

Only in stage 3 do you plan the actual lessons. Now the question becomes: "What instruction, practice, and learning experiences will give students the knowledge, skills, and understanding needed to demonstrate on the assessment?"

This ordering prevents the common mistake of teaching interesting activities that aren't actually connected to the learning goals. Every lesson in a backwards-designed unit answers the question: "How does this bring students closer to the assessment?"

Connecting to LessonDraft

When you know where you're going (the assessment) and what it requires (the understandings), building individual lessons becomes more efficient: you're not deciding what to teach, you're deciding how to best prepare students for a known target.

The Practical Challenge

Backwards design requires more up-front planning time than forward planning. You need to design the assessment before you design the lessons. This is uncomfortable for teachers who are used to working one week ahead — backwards design works better at the unit level, which requires several weeks of planning in advance.

The payoff: once the unit is designed, the daily lesson planning becomes much cleaner. You know what you're working toward; the question is just what's the most efficient path there.

Common Backwards Design Mistakes

Writing understanding goals that are actually knowledge goals. "Students will understand the causes of World War I" is really a knowledge goal. "Students will understand that geopolitical events have complex, interacting causes that resist simple explanation" is an understanding goal that transcends the specific content.

Designing performance tasks that don't actually require transfer. A performance task should put students in a novel context that requires them to apply understanding, not just recall. If students could perform the task by copying what was in the notes, it's not a performance task.

Skipping stage 2. Many teachers do stages 1 and 3 but treat assessment as an afterthought. If assessment isn't designed before instruction, the instruction tends to cover content without targeting understanding. Stage 2 is the hinge that connects your goals to your lessons.

One Entry Point

If backwards design feels like too much overhead to implement all at once: start with one unit and one clear performance task. Ask yourself before you plan a single lesson: "What would a student be able to do at the end of this unit that would prove to me they actually got it?" Design that task. Then plan backward from it.

That single shift — assessment before instruction — is the core move. The rest of the framework fills in around it.
