What is Problem Solving? Solving problems is not only a goal of learning
mathematics but also a major means of doing so… Problem solving is an integral part of all mathematics learning, and so it should not be an isolated part of mathematics program. Problem solving in mathematics should involve all the five content areas described in these standards … Good problems will integrate multiple topics and will involve significant mathematics.
-NCTM, Principles and Standards for School Mathematics. (2000), p.52

Mathematical Practices Make sense of problems and persevere in
solving them Reason abstractly and quantitatively Construct viable arguments and critique the
reasoning of others Model with mathematics Use appropriate tools strategically Attend to precision Look for and make use of structure Look for and express regularity in repeated
reasoning

Questions…. How are you providing an opportunity for
your students to apply and explain the mathematical practices?
How are you including writing in your math program?
![Page 13: Problem solving strategies IN GRADES K - 2](https://reader033.vdocuments.us/reader033/viewer/2022052704/56816764550346895ddc4287/html5/thumbnails/13.jpg)
Writing for Problem Solving in Math Class
“When students write, their papers provide a window into their understandings, their misconceptions, and their feelings about the content.”
M. Burns, “Writing in Math,” Education Leadership, 62(2)(October 2004), p.30
![Page 14: Problem solving strategies IN GRADES K - 2](https://reader033.vdocuments.us/reader033/viewer/2022052704/56816764550346895ddc4287/html5/thumbnails/14.jpg)
Rationale Organize and consolidate their
mathematical thinking through communication
Communicate mathematical thinking coherently and clearly to others
Analyze and evaluate mathematical thinking and strategies of others
Use the language of mathematics to express mathematical ideas precisely.
NCTM, Principles and Standards for School Mathematics. (2000)

Selecting the Problem Solving Task
Does this problem promote application of the mathematical ideas presented in the current instructional focus or unit of study?
Does this problem match students’ current instructional level?
Is this problem accessible to all students? Is the problem relevant and engaging to
students? Does this problem require students to
“stretch” their mathematical reasoning abilities?
![Page 17: Problem solving strategies IN GRADES K - 2](https://reader033.vdocuments.us/reader033/viewer/2022052704/56816764550346895ddc4287/html5/thumbnails/17.jpg)
Selecting the Problem Solving Task (cont)
Does this problem involve more than one strand or standard of mathematics?
Is there more than one way to solve the problem?
Could the problem be extended or enriched?
Do I fully understand the mathematics in this problem, so that I can better facilitate student understanding?
![Page 18: Problem solving strategies IN GRADES K - 2](https://reader033.vdocuments.us/reader033/viewer/2022052704/56816764550346895ddc4287/html5/thumbnails/18.jpg)
Goal for Problem Solving at the Primary Grade Levels
Ultimate goal for primary grade students is for them to be able - by the end of the school year – to solve a multistep problem and to communicate verbally and in writing the process they used.
![Page 19: Problem solving strategies IN GRADES K - 2](https://reader033.vdocuments.us/reader033/viewer/2022052704/56816764550346895ddc4287/html5/thumbnails/19.jpg)
Scaffolds to Meet Goal Model the process for the whole class
until familiar Student solve the selected problems in
cooperative groups or selected teams Partner students to solve a given
problem together We expect students to be able to
complete the entire process independently
![Page 20: Problem solving strategies IN GRADES K - 2](https://reader033.vdocuments.us/reader033/viewer/2022052704/56816764550346895ddc4287/html5/thumbnails/20.jpg)
Whole Class Instruction Teacher and students read the problem
together. The teacher makes sure the student understands what the problem is asking
Students work 5 to 10 minutes to solve the problem individually, with manipulatives (recording work on paper)
Students share possible strategies for solving the problem
Teacher and students decide on a solution(s) to the problem
![Page 21: Problem solving strategies IN GRADES K - 2](https://reader033.vdocuments.us/reader033/viewer/2022052704/56816764550346895ddc4287/html5/thumbnails/21.jpg)
Whole Class Instruction (cont) Teacher creates a class Data Sheet Students copy the Data Sheet Teacher and students compose a few
sentences to describe how the problem was solved
Teacher records the sentences on chart paper to be posted in the classroom
Students copy the class-written explanation
![Page 22: Problem solving strategies IN GRADES K - 2](https://reader033.vdocuments.us/reader033/viewer/2022052704/56816764550346895ddc4287/html5/thumbnails/22.jpg)
Cooperative Teams Teacher arranges the students into small
cooperative groups Guided by teachers, students attempt to
solve a new problem Using words, pictures, and/or numbers,
the students complete the Data Sheet The students then complete then work
onto Chart Paper Students share out to the rest of the
class
![Page 23: Problem solving strategies IN GRADES K - 2](https://reader033.vdocuments.us/reader033/viewer/2022052704/56816764550346895ddc4287/html5/thumbnails/23.jpg)
Benefits of Cooperative Teams Different teams will describe their
process differently and thus add to everyone’s understanding of the problem
Examples around the room will provide references for the next solving activity
Math team posters are updated regularly which keeps student interest in the problem solving process
