Help students reveal the math behind the words: “I don’t get what I’m supposed to do!” This is a common refrain from students when asked to solve word problems. Solving problems is about more than computation. Students must understand the mathematics of a situation to know what computation will lead to an appropriate solution. Many students often pluck numbers from the problem and plug them into an equation using the first operation they can think of (or the last one they practiced). Students also tend to choose an operation by solely relying on key words that they believe will help them arrive at an answer, which without careful consideration of what the problem is actually asking of them. Mathematize It! Going Beyond Key Words to Make Sense of Word Problems, Grades 3-5 shares a reasoning approach that helps students dig into the problem to uncover the underlying mathematics, deeply consider the problem’s context, and employ strong operation sense to solve it. Through the process of mathematizing, the authors provide an explanation of a consistent method—and specific instructional strategies—to take the initial focus off specific numbers and computations and put it on the actions and relationships expressed in the problem. Sure to enhance teachers’ own operation sense, this user-friendly resource for Grades 3û5: Offers a systematic mathematizing process for students to use when solving word problems; Gives practice opportunities and dozens of problems to leverage in the classroom; Provides specific examples of questions and explorations for all four operations; (addition, subtraction, multiplication, and division) with whole numbers, fractions, and decimals; Demonstrates the use of concrete manipulatives to model problems with dozens of short videos; Includes end-of-chapter activities and reflection questions.
