THE FOURSTEP PROBLEM SOLVING PLAN

Overview of “FourStep Problem Solving”
The “FourStep Problem Solving” plan helps elementary math students to employ sound reasoning and to develop mathematical language while they complete a fourstep problemsolving process. This problemsolving plan consists of four steps: details, main idea, strategy, and how. As students work through each step, they may use “graphic representations” to organize their ideas, to provide evidence of their mathematical thinking, and to show their strategy for arriving at a solution.
Main Idea
In this step, the student is a reader, a thinker, and an analyzer. First, the student reads over the problem and finds any proper nouns (capitalized words). If unusual names of people or places cause confusion, the student may substitute a familiar name and see if the question now makes sense. It may help the student to reread the problem, summarize the problem, or visualize what is happening. When the student identifies the main idea, he or she should write it down, using words or phrases; that is, complete sentences are unnecessary. Students need to ask themselves questions such as the ones shown below.
 “What is the main idea in the question of this problem?”
 “What are we looking for?”
 “What do we want to find out?”
Details
The student reads the problem again, sentence by sentence, slowly and carefully. The student identifies and records any details, using numbers, words, and phrases. The student looks for extra information—that is, facts in the reading that do not figure into the answer. In this step, the student should also look for hidden numbers, which may be indicated but not clearly expressed. (Example: The problem may refer to “Frank and his three friends.” In solving the problem, the student needs to understand that there are actually four people, even though “four” or “4” is not mentioned in the reading.) Students ask themselves the following kinds of questions.
 “What are the details needed to answer the question?”
 “What are the important details?”
 “What is going on that can help me answer the question?”
 “What details do I need?”
Strategy
The student chooses a math strategy (or strategies) to find a solution to the problem and uses that strategy to find the answer/solve the problem. Possible strategies, as outlined in the Texas Essential Knowledge and Skills (TEKS) curriculum, include the following.
 use or draw a picture
 look for a pattern
 write a number sentence
 use actions (operations) such as add, subtract, multiply, divide
 make or use a table
 make or use a list
 work a simpler problem
 work backwards to solve a problem
 act out the situation
The preceding list is just a sampling of the strategies used in elementary mathematics. There are many strategies that students can employ related to questions such as the following.
 “What am I going to do to solve this problem?”
 “What is my strategy?”
 “What can I do with the details to get the answer?”
How
To make sure that their answer is reasonable and that they understand the process clearly, students use words or phrases to describe how they solved the problem. Students may ask themselves questions such as the following.
 “How did I solve the problem?”
 “What strategy did I use?”
 “What were my steps?”
In this step, students must explain the solution strategy they have selected. They must provide reasons for and offer proof of the soundness of their strategy. This step gives students the opportunity to communicate their understanding of math concepts and math vocabulary represented in the problem they solved and to justify their thinking.
Responses on these four parts need not be lengthy—a list of words and numbers might be used for the details, and phrases might be used for the “Main Idea” and “How.”
Benefits of Using “FourStep Problem Solving Plan”
One of the method's major benefits to students is that it forces them to operate at high levels of thinking. Teachers, using the triedandtrue Bloom’s Taxonomy to describe levels of thinking, want to take students beyond the lower levels and help them reach the upper levels of thinking. Doing the multiple step method requires students to record their thinking about three steps in the process, in addition to actually "working the problem."
A second benefit of extending the process from three steps to four is that having students think at these levels will deepen their understanding of mathematics and improve their fluency in using math language. In the short term, students' performance on assessments will improve, and confidence in their mathematical ability will grow. In the long term, this rigor in elementary school mathematics will prepare students for increased rigor in secondary mathematics, beginning particularly in grade 7.
Another benefit of using “FourStep Problem Solving” is that it will increase teachers’ ability to identify specific problems students are having and provide them with information to give specific corrective feedback to students.
Extracting and writing the main idea and details and then showing the strategies to solve problems should also help students establish good testtaking habits for online testing.
Educational Research Supporting “FourStep Problem Solving”
Although scholarly articles do not mention “FourStep Problem Solving” by name, most educational experts do advocate the use of multistep problemsolving methods that foster students’ performing at complex levels of thinking. The number of steps often ranges from four to eight.
Conclusions drawn from studying the work of metaresearcher Dr. Robert Marzano published in the book Classroom Instruction That Works (Marzano, Pickering, Pollock) as well as numerous other research studies, indicate that significant improvement in student achievement occurs when teachers use these strategies.

All Steps
The National Council of Teachers of Mathematics endorses the use of such strategies as those appearing in “FourStep Problem Solving”—particularly the step requiring students to explain their answers—as effective for producing students’ math competency, as described in NCTM publications such as Principles and Standards for School Mathematics. Excerpts from NCTM documents validate the district's problemsolving strategy. Some of the key ideas and teaching standards identified include the following.
 Teachers need to investigate how their students arrive at answers. Correct answers don't necessarily equate to correct thinking.
 Students need to explore various ways to think about math problems and their solutions.
 Students need to learn to analyze and solve problems on their own.
 Students' discourse in a mathematics classroom should focus on their thinking process as they solved a problem.
Relationship of “FourStep Problem Solving” and the TEKS
Although the TEKS for elementary math do not mention a graphic organizer for problemsolving, they do require that students in grades 15 learn and do the following things in the area of “Underlying Processes and Mathematical Tools.”
 The student applies mathematics to solve problems connected to everyday experiences and activities in and outside of school.
 Identify the mathematics in everyday situations.
 Solve problems that incorporate understanding the problem, making a plan, carrying out the plan, and evaluating the solution for reasonableness.
 Select or develop an appropriate problemsolving plan or strategy, including drawing a picture, looking for a pattern, systematic guessing and checking, acting it out, making a table, working a simpler problem, or working backwards to solve a problem.
 Use tools such as real objects, manipulatives, and technology to solve problems.
 The student communicates about mathematics using informal language.
 Explain and record observations using objects, words, pictures, numbers, and technology.
 Relate informal language to mathematical language and symbols.
 The student uses logical reasoning to make sense of his or her world.
 Make generalizations from patterns or sets of examples and nonexamples.
 Justify why an answer is reasonable and explain the solution process.
Instructional Methods Behind “FourStep Problem Solving”
Teachers will use a variety of techniques as they instruct students regarding “FourStep Problem Solving.” They will
 model use of the “FourStep Problem Solving Plan” with graphic representations as they guide students through the fourstep problemsolving process;
 use a thinkaloud method to share their reasoning with students;
 employ questioning strategies that provoke students to higher levels of thinking; and
 foster rich dialogue, both in wholeclass discussions and for partner/table activities.
For success with “FourStep Problem Solving,” talking must occur prior to writing. Students will be shown how to bridge the span between math and language to express their reasoning in a way that uses logical sequences and proper math vocabulary terms. Once students have mastered the ability to communicate out loud with the teacher and with peers, they can transition to developing the skill of conducting an “internal dialogue” for solving problems independently.
Students Using “FourStep Problem Solving”
Use of a common graphic organizer at all schools would greatly benefit our evershifting population of students—not only those whose families move often, but also those affected by boundary changes we continue to experience as we grow. Districtwide staff development has focused on acquainting all elementary math teaching staff with “FourStep Problem Solving,” and outlining expectations for students’ problemsolving knowledge and skills outlined in the TEKS at each gradelevel.
Because it is the steps in the problem that are important, not the graphic representation itself, vertical math teams on each campus, working with the building principal, have the option of selecting or designing a graphic organizer, as long as it fulfills the fourstep approach. Alternatives to “The Q” include a fourpane “window pane” or a simple list of the four steps. Another scheme adopted by some schools is being called SQRQCQHQ, which uses the old three steps plus a new fourth step—the “HQ” is the "how" step. Schools using SQRQCQHQ should consider how the advent of online testing will impact its use.
Putting “The FourStep Problem Solving Plan” into Action
In class, students will use “FourStep Problem Solving” in a variety of circumstances.
 Students will participate in wholeclass discussion and completion of “FourStep Problem Solving” pages as the teacher explains math problems to the group. To guide students through the steps, teachers may place a “FourStep Problem Solving Organizer” transparency on the overhead, affix a “FourStep Problem Solving Organizer” visual aid to the white board, use a “FourStep Problem Solving Organizer” poster, or simply draw a “FourStep Problem Solving Organizer” on the board to fill in the areas of the graphic organizer so that students observe how to solve the problems.
 Students will work in pairs to complete daily work with a partner using fourstep problem solving. Having a partner allows the students to discuss aspects of the problemsolving process, a grouping arrangement which helps them develop the language skills needed for completing the steps of the problemsolving process.
 Students will complete assignments on their own using the four steps, allowing teachers to gauge their ability to master the steps needed to complete the problemsolving process.
Students can expect to see “FourStep Problem Solving” used in all phases of math instruction, including assessments. Students will be given problems and asked to identify the main idea, details, and process used, as well as solve for a calculation.
The district’s expectation is that students will ultimately use “FourStep Problem Solving” for all story problems, unless directed otherwise. When students clearly understand the process and concepts they are studying, teachers may choose to limit the writing of the “how.” Improved student achievement comes in classrooms that routinely and consistently use all four steps of the process.
Using this approach should reduce the number of problems students are assigned. Completing the “FourStep Problem Solving” should take only a few minutes. As students become familiar with the graphic organizer, they will be able to increase the pace of their work. Students can save time by writing only the main idea (instead of copying the entire question) and by using words or phrases in describing the “how” (instead of complete sentences).
For years, researchers of results on the National Assessment of Educational Progress ( NAEP ) and the Trends in International Mathematics and Science Study ( TIMSS ) have cited curricular and instructional differences between U.S. schools and schools in countries that outperform us in mathematics. For example, Japanese students study fewer concepts and work fewer problems than American students do. In Japan , students spend their time in exploring multiple approaches to solving a problem, thereby deepening their understanding of mathematics. Depth of understanding is our goal for students, too, and we believe that the fourstep problemsolving plan will help us achieve this goal.
The ultimate goal is that students learn to do the four steps without the use of a preprinted form. This ability becomes necessary on assessments such as TAKS, since security rules prohibit the teacher from distributing any materials. In 2007, when students may first be expected to take TAKS online, students will need a plan for problemsolving on blank paper to ensure that they don’t just, randomly select an answer—they can’t underline and circle on the computer monitor’s glass.
Assessment and Grading with “The FourStep Problem Solving Plan”
Assignments using “The FourStep Problem Solving Plan” may include daily work, homework, quizzes, and tests (including districtdeveloped benchmarks). CFISD’s gradeaveraging software includes options for all these categories. As with other assignments, grades may be taken for individuals or for partners/groups. Experienced teachers are already familiar with all these grading scenarios.
Teachers may use a rubric for evaluating student work. The rubric describes expectations for students’ responses and guides teachers in giving feedback. Rubrics may be used in many subjects in school, especially for reviewing students’ written compositions in language arts.
A range of “partial credit” options is possible, depending on the teacher’s judgment regarding the student’s reasoning and thoroughness. Students may be asked to redo incomplete portions to earn back points. Each campus makes a decision about whether the process will be included in one grade or if process will be a separate grade.
Knowledge of students’ thinking will help the teacher to provide the feedback and/or the reteaching that will get a struggling student back on track, or it will allow the teacher to identify students who have advanced understanding in mathematics so that their curriculum can be adjusted. Looking at students' work and giving feedback may require additional time because the teacher is examining each student's thought processes, not just checking for a correct numeric answer.
Because students’ success in communicating their understanding of a math concept does not require that they use formal language mechanics (complete sentences, perfect spelling, etc.) when completing “The FourStep Problem Solving Plan,” the rubric does not address these skills, leading math teachers to focus and assign grades that represent the students’ mastery of math concepts.
