Back To School Tasks
We have chosen this collection of K-12 tasks as they engage students actively in mathematical thinking, reasoning, convincing and other great ways of being mathematical, to help set norms for the year. We have also set out our recommendations and strategies for positive norm setting in our accompanying document. Moving Colors (Grades K-2) Here’s a really nice task sent to us by Deb Morton, a K-1 teacher, in Vista Unified.

Why Is Teaching With Problem Solving Important to Student Learning? Brief
Problem solving plays an important role in mathematics and should have a prominent role in the mathematics education of K-12 students. However, knowing how to incorporate problem solving meaningfully into the mathematics curriculum is not necessarily obvious to mathematics teachers. (The term “problem solving” refers to mathematical tasks that have the potential to provide intellectual challenges for enhancing students’ mathematical understanding and development.) Fortunately, a considerable amount of research on teaching and learning mathematical problem solving has been conducted during the past 40 years or so and, taken collectively; this body of work provides useful suggestions for both teachers and curriculum writers.

math progressions by domain
The Common Core State Standards in mathematics were built on progressions: narrative documents describing the progression of a topic across a number of grade levels, informed both by research on children's cognitive development and by the logical structure of mathematics. These documents were spliced together and then sliced into grade level standards. From that point on the work focused on refining and revising the grade level standards.

When you hear a teacher's stories of classroom instruction, you hear the wisdom of practice through those stories. Classroom stories are a valuable repository of practical knowledge. At LessonSketch we believe that those representations of practice may also provide context for developing capacity for instruction. The LessonSketch collections, tools, and online community are devoted to the creation, examination, and discussion of stories of instructional practice.

Featured Topic: Back-to-School Glyphs Glyphs are a pictorial form of data collection. You might be reminded of the term "hieroglyphics" and think about early picture writing. Different forms of glyphs are used in many medical situations to quickly record data about a patient in pictorial form.

SMART Boards and the Tips-and-Tricks Phenomenon
A really awesome phenomenon about the Internet is the viral nature of sharing information. In other words, good information spreads quickly throughout niche areas. A case in point...yesterday, I ran across a relatively new blog called elearnr (cool name!) that had a post called Ten Ways to Use Your Interactive Whiteboard More Effectively. It is a very well written post by Doug Belshaw that expands on a Google Docs presentation called Thirty-Seven Interesting Ways to Use Your Interactive Whiteboard (see below).
Standards for Mathematical Practice
"Does this make sense?" Mathematically proficient students start by explaining to themselves the meaning of a problem and looking for entry points to its solution. They analyze givens, constraints, relationships, and goals. They make conjectures about the form and meaning of the solution and plan a solution pathway rather than simply jumping into a solution attempt. They consider analogous problems, and try special cases and simpler forms of the original problem in order to gain insight into its solution.
