# Mystery Problem

This strategy is a biweekly problem solving investigation on recently learned content. Typically students will be given sample scanned answers that I have hand selected. These problems have been previously solved. Students meet on the carpet for the mystery problem reveal. We also cover what the goal of our session will be using a checklist/success rubric. They are then dismissed to investigate in teams. The students select manipulatives to discuss, develop an agreed upon idea, and critique which student(s) response they agree with/why. If a team finishes early they can work on they "Step ahead" which is harder differentiated task. Finally they use the checklist to self reflect if they were successful during the mystery problem session.

Lesson Plan

The Checklist/Rubric is an assessment tool students use to convey where they are with their task for the lesson or team task. The checklist has indicators students select from: starting to [understand], not yet, and Yes! The rubric is checked off as the team progresses through the lesson and at the conclusion they evaluate how they did. Using this rubric with student friendly language allows students to determine what there next steps may be during a lesson, provide constructive feedback to one another, or consider what they need work on to be ready for the next lesson.
Student Work Sample

The sample slides show the progression of the mystery problem. We start by revealing and reviewing the self-assessment checklist, consider what we know about the topic and move on to the mystery. Within the mystery problem slide, students determine which student written solution from their math journals is correct by solving the problem in their teams. Students are free to select any manipulatives we have available during the mystery problem team time.

Assessment & Data

Assessment and data play a crucial role in a blended teacherâ€™s classroom. Blended learning gives teachers an opportunity to assess consistently throughout a class, in a way that drives instruction, impacts grouping, and assignments. Blended educators have to develop capacity to sift through multiple sources of data and synthesizes quickly into action. Check out how Freddy utilizes Assessment and Data here.

Independent Student Learning

Each of my students is given the option to use different notepads, lined or grid paper, and scratch paper we have. This strategy is implemented to develop students' ability to convey understanding using models or ideas that they have when using our math software. Students in this clip are given ideas about how to express their thinking using our math strategies card along the computer. Students use the notepads or paper to refer back to their previous notes, and to also help one another by referring back to notes where applicable.

Stakeholder Collaboration

At our blended school, we value data in all forms, whereby we seek to meet both the academic and behavioral needs of our students. In the elementary school setting, where we assess reading levels every six weeks, we also assess student growth and mastery in each studentâ€™s blended learning every quarter and assess behavioral trends on a monthly basis.
