Problem Solving : Problem Solving A situation that confronts an individual or group that requires resolution, and for which the individual sees not apparent or obvious means or path to obtaining a solution.
(Stephen Krulik and Jesse Rudnick)
Math Reasoning : Math Reasoning The part of thinking that goes beyond the recall level. It includes basic, critical, and creative thinking. It does not include recall.
Research on Problem Solving and Reasoning : Research on Problem Solving and Reasoning 1. Math reasoning is both nurtured and natural in collaborative communities
2. Math reasoning needs to occur in real contexts
3. Reasoning and higher order thinking often yield multiple solutions
4. Young children and lower-ability students can learn and use the same reasoning strategies and higher-order thinking skills that are used by high-ability students
5. Teachers’ emphasis on specific problem solving strategies as an integral part of instruction does significantly impact their students’ problem solving performance
6. Students solving a math problem in small groups use cognitive behaviors and processes that are essentially similar to those of expert math problem solvers
7. A reasonable amount of of tension and discomfort improves the problem solving performance of students
Elements of Problem Solving and Reasoning : Elements of Problem Solving and Reasoning 1. Students need to work the 5 steps of problems solving
2. George Polya's 10 problems solving strategies
3. Math reasoning skills for problems that contain too much information or not enough information
4. Open-ended problem experience
5. Students need to see examples of actual student work so they understand rubrics and standards (“Why I did what I did.” Not “What I did.”
6. Problem solving in groups a majority of the time
What’s Out There? : What’s Out There? NCS Mentor
The Exemplars

Problem Solving and Reasoning in the Elementary Classroom
K-4 and 5-7 Math Toolkit
“Minute Math” from Everyday Math
Teacher to Teacher Materials
Internet Sites
NCS Mentor : NCS Mentor Computer-based application for WASL questions in math, reading, and writing
Advantages
Students and teachers learn exactly what WASL questions look like.
Sample papers are available to practice rubric grading and thus students understand what a “4” looks like.
Disadvantages
Many school servers have a difficult time running the program smoothly.
There is a limited bank of questions.
If you want to give instruction, you need an overhead projection system for the computer.
Slide8 : Advantages
Math Problems for Kindergarten
Rubrics and sample papers to assist in grading
Problems are organized by grade level and math strand
New problems come out twice a year
Disadvantages
Problems need to be placed on the school server (many of CD-ROM’s have been lost by individuals)
The grading rubric does not align exactly with the Washington State EALR’s
Slide9 : Advantages
Teaches the 10 problem solving strategies
Has blackline masters for students to practice
Provides solutions Disadvantages
Provided problems do not include ones with superfluous information amd not enough information (does not teach reasoning)
There is too much flowery language which make it difficult for students, especially ESL students, to read
Too teacher directed The Problem Solver
Slide10 : Disadvantages
Requires more time to understand lessons and concepts than other resources Advantages
Teaches reasoning skills like superfluous information or not enough information
Has open-ended Problems
Provides blackline masters for students
Lessons for grades 1-6
K-4 and 5-7 Toolkits : K-4 and 5-7 Toolkits Advantages
Classroom-based assessments aligned with EALR’s and Kent School District SLO’s
Gives a good picture of how students are doing to meet Washington State benchmarks
Has activities from all math strands
Includes teacher directions
Good Preparation for the WASL
Disadvantages
Activities are not presented by grade level
Slide12 : Advantages
Takes very little time
Builds number sense and concepts by providing real world applications
Included in Everyday Math Kits grades K-3 Disadvantages
Only available for lower grades
Teacher to Teacher : Teacher to Teacher Advantages
Contains warm-up activities
Sample papers for assessment
Aligns with Washington State EALR’s and Benchmarks
Similar format to WASL
Disadvantages
Contains only about 15 total problems
