Callan Method Teacher Book' title='Callan Method Teacher Book' />Modeling Word Problems Sci. Math. MNUsing models is a critical step in helping students transition from concrete manipulative work with word problems to the abstract step of generating an equation to solve contextual problems. By learning to use simple models to represent key mathematical relationships in a word problem, students can more easily make sense of word problems, recognize both the number relationships in a given problem and connections among types of problems, and successfully solve problems with the assurance that their solutions are reasonable.

What is the Callan Method How it words and how do you use it for improving english speaking. We have been giving you information about Rules. You can remember. Mr. Alexander and teachers from his grade level team were talking during their Professional Learning Community PLC meeting about how students struggle with word problems. Everyone felt only a few of their students seem to be able to quickly generate the correct equation to solve the problem. Many students just seem to look for some numbers and do something with them, hoping they solve the problem. Mr. Alexander had recently learned about using modeling for word problems in a workshop he had attended. He began to share the model diagrams with his teammates and they were excited to see how students might respond to this approach. They even practiced several model diagrams among themselves as no one had ever learned to use models with word problems. Since part of their PLC work freed them up to observe lessons in each others rooms, they decided they would watch Mr. Alexander introduce modeling to his students. So, two days later they gathered in Mr. Alexanders room for the math lesson. Mr. Alexander presented the following problem Lily and her brother, Scotty, were collecting cans for the recycling drive. One weekend they collected 5. How many cans were collected in all Mr. Alexander went over the problem and drew a rectangular bar divided into two parts on the board, explaining that each part of the rectangle was for the cans collected on one of the weekends and the bracket indicated how many cans were collected in all. Reviewing the problem, Mr. Alexander asked students what was not known, and where the given numbers would go and why. This resulted in the following bar model The class then discussed what equations made sense given the relationship of the numbers in the bar model. This time many students wrote the equation, 5. In their discussion after the lesson, Mr. Callan Method Teacher Book' title='Callan Method Teacher Book' />Alexanders teammates mentioned that they noticed a much higher degree of interest and confidence in problem solving when Mr. Alexander introduced the bar model. Everyone noticed that many more students were successful in solving problems once modeling was introduced and encouraged. As the class continued to do more word problems, the diagrams appeared to be a helpful step in scaffolding success with word problems. Word problems require that students have the skills to read, understand, strategize, compute, and check their work. Thats a lot of skills Following a consistent step by step approach and providing explicit, guided instruction in the beginning can help our students organize their thoughts and make the problem solving task manageable. Forsten, 2. 01. 0, p. Students often have regarded each word problem as a new experience, and fail to connect a given problem to past problems of a similar type. Students need to sort out the important information in a word problem, and identify the relationships among the numbers involved in the situation. A model can help students organize their thinking about a given problem, and identify an equation that would be helpful in solving the problem. Models are a kind of graphic organizer for the numbers in a word problem, and may connect to students work with graphic organizers in other subjects. The failure to capture the mathematics being taught with a picture that helps students visualize what is going on is one of the most serious missed opportunities I observe. Leinwand, 2. Modeling can begin with young learners with basic addition, subtraction, multiplication, and division problems. Modeling can be extended to ratio, rate, percent, multi step, and other complex problems in the upper grades. Utilizing modeling on a routine basis in early grades can lay an important foundation for later work, including the transition to algebra, by stressing patterns, generalizations, and how numbers relate to each other. Knowledge can be represented both linguistically and nonlinguistically. An increase in nonlinguistic representations allows students to better recall knowledge and has a strong impact on student achievement Marzano, et. Section 5. In classic education research, Bruner 1. The iconic stage, using pictures and diagrams, is an important bridge to abstracting mathematical ideas using the symbols of an equation. Powerquest Drive Image 2002 Free Download on this page. Research has also validated that students need to see an idea in multiple representations in order to identify and represent the common core Dienes, undated. For word problems involving the operation of addition, students need to experience several types of problems to generalize that when two parts are joined they result in a total or a quantity that represents the whole. Whether the items are bears, balloons, or cookies no longer matters as the students see the core idea of two subsets becoming one set. Dienes discovered that this abstraction is only an idea therefore it is hard to represent. Diagrams can capture the similarity students notice in additionjoining problems where both addends are known and the total or whole is the unknown. Diagrams will also be useful for missing addend situations. Like Bruner, Dienes saw diagrams as an important bridge to abstracting and formalizing mathematical ideas. Along with Bruner and Dienes, Skemp 1. While students need to experience many real life situations they will get bogged down with the noise of the problem such as names, locations, kinds of objects, and other details. It is the teachers role to help students sort through the noise to capture what matters most for solving the problem. A diagram can help students capture the numerical information in a problem, and as importantly, the relationship between the numbers, e. Do we know both the parts, or just one of the parts and the wholeAre the parts similar in size, or is one larger than the other Once students are comfortable with one kind of diagram, they can think about how to relate it to a new situation. A student who has become proficient with using a part part whole bar model diagram when the total or whole is unknown, as in the collecting cans problem in Mr. Alexanders class, cannot only use the model in other part part whole situations, but can use it in new situations, for example, a missing addend situation. Given several missing addend situations, students may eventually generalize that these will be subtractive situations, solvable by either a subtraction or adding on equation. The work of Bruner, Dienes and Skemp informed the development of computation diagrams in some elementary mathematics curriculum materials in the United States. Interestingly, it also informed the development of curriculum in Singapore, as they developed the Thinking Schools, Thinking Nation era of reforming their educational model and instructional strategies Singapore Ministry of Education, 1.
