The mission

Getting the story right means following the evidence, not the rumor.

The Mystery puts your fourth graders on a committee investigating who tampered with the school time capsule. They read interview transcripts, news articles, and documents, weigh what each source actually proves, and write a report. On Day 3 a sensational news headline tempts the whole school toward the wrong answer. It is close reading that has a verdict riding on it.

The Mystery Day 3 student file with the news article

A worksheet cannot do what a real decision does.

Your fourth graders are not answering questions about a passage. They are an investigative committee, reading transcripts and documents to figure out who tampered with the time capsule. On Day 3 a dramatic news headline sweeps the school toward an easy answer, and the team has to decide whether the evidence actually supports it. The teams who read carefully separate what a source proves from what it merely suggests. That is reading for evidence, with a real conclusion on the line.

The grading note: graded on reasoning, not the verdict

They are graded on their thinking, not on the verdict.

Here is the part teachers do not expect. A team that named the right culprit is not graded higher than a team that did not. Getting it right is not the point. Students are graded on the quality of their reasoning, written in their own reflection. A team that reached the wrong conclusion but weighed the evidence honestly scores higher than a team that guessed correctly. That is how a fourth grader learns that how you reason matters more than whether you guessed right.

The student workbook logging sources and evidence

Let the workbook keep the evidence straight.

The Mystery comes with a workbook that tracks every source, every clue, and what each one actually establishes. The team logs what they read, and the record builds itself. Their attention stays on the hard part, deciding which evidence is solid and which is just a rumor dressed up as a fact, instead of on keeping track of it all.

The teacher guide daily playbook

Five days, already scripted. You just run the room.

You do not need a system for teaching evidence-based reading. The guide scripts every day, tells you what students will likely say, and hands you exactly how to respond. The transcripts, the misleading headline, the committee report, and the Day 5 reveal are all written for you. You bring the facilitation. The mission brings everything else.
