## What is Math Expressions?

Math Expressions is a research-based math curriculum that was developed by Dr. Karen Fuson, a professor emeritus of learning sciences at Northwestern University. It is based on the idea that students learn best when they can express their mathematical thinking in multiple ways, such as using words, symbols, models, drawings, and manipulatives. Math Expressions also incorporates the latest findings from cognitive science, such as how students develop number sense, problem-solving skills, algebraic reasoning, and conceptual understanding.

Math Expressions covers all the domains and standards of the Common Core State Standards for Mathematics (CCSSM), such as operations and algebraic thinking, number and operations in base ten, number and operations-fractions, measurement and data, and geometry. It also integrates mathematical practices, such as making sense of problems, reasoning abstractly and quantitatively, constructing viable arguments, modeling with mathematics, using appropriate tools strategically, attending to precision, looking for and making use of structure, and looking for and expressing regularity in repeated reasoning.

Math Expressions consists of several components that work together to provide a coherent and rigorous math education for students. These include:

Student Activity Book: This is where students complete their daily lessons, activities, games, explorations, investigations, projects, writing prompts, vocabulary cards, etc. It contains colorful illustrations, examples, scaffolds, hints, tips, reminders, checkpoints, self-assessments, etc.

Homework and Remembering: This is where students practice and review what they learned in class. It contains two pages per lesson that include homework problems, remembering problems (spiral review), and math boxes (additional practice). It also contains unit reviews, unit tests, cumulative reviews, and cumulative tests.

Teacher Edition: This is where teachers find the lesson plans, objectives, standards, materials, differentiation, assessment, and professional development resources. It contains detailed instructions, explanations, examples, questions, prompts, suggestions, etc.

Online Resources: This is where students and teachers can access digital versions of the Student Activity Book and Homework and Remembering, as well as interactive tools, games, videos, animations, e-books, assessments, reports, etc.

Math Expressions is divided into two volumes per grade level. Volume 1 covers the first half of the school year, and Volume 2 covers the second half. Each volume has six or seven units that focus on a specific domain or topic. Each unit has several lessons that are organized into three phases: Launch (introduction and exploration), Learn (instruction and practice), and Land (reflection and assessment).

To use Math Expressions Grade 4 Homework and Remembering Volume 2 effectively, you should follow these steps:

Complete the homework problems for each lesson: After each lesson in the Student Activity Book, you will find a corresponding page in the Homework and Remembering book that has homework problems. These problems are similar to the ones you did in class, but they may have different numbers or contexts. You should complete these problems on your own or with a partner, using the strategies and methods you learned in class. You should also check your answers with the answer key at the end of the book or online.

Complete the remembering problems for each lesson: After the homework problems, you will find another page in the Homework and Remembering book that has remembering problems. These problems are spiral review questions that cover previous concepts and skills from earlier units or lessons. You should complete these problems on your own or with a partner, using your prior knowledge and notes. You should also check your answers with the answer key at the end of the book or online.

Complete the math boxes for each lesson: After the remembering problems, you will find another page in the Homework and Remembering book that has math boxes. These are additional practice problems that extend or enrich your learning of the current concept or skill. You should complete these problems on your own or with a partner, using your creativity and curiosity. You should also check your answers with the answer key at the end of the book or online.

Complete the unit review before each unit test: Before each unit test in the Student Activity Book, you will find a unit review in the Homework and Remembering book that has review problems. These problems are comprehensive questions that cover all the concepts and skills from the current unit. You should complete these problems on your own or with a partner, using your notes and resources. You should also check your answers with the answer key at the end of the book or online.

Complete the unit test after each unit review: After each unit review in the Homework and Remembering book, you will find a unit test in the Student Activity Book that has test problems. These problems are similar to the ones you did in class, but they may have different numbers or contexts. You should complete these problems on your own or with a partner, using your best effort and strategies. You should also check your answers with the answer key at the end of the book or online.

Complete the cumulative review before each cumulative test: Before each cumulative test in the Student Activity Book, you will find a cumulative review in the Homework and Remembering book that has review problems. These problems are comprehensive questions that cover all the concepts and skills from all the previous units. You should complete these problems on your own or with a partner, using your notes and resources. You should also check your answers with the answer key at the end of the book or online.

Complete the cumulative test after each cumulative review: After each cumulative review in the Homework and Remembering book, you will find a cumulative test in the Student Activity Book that has test problems. These problems are similar to the ones you did in class, but they may have different numbers or contexts. (2 x 1) - (2 x 100) + (4 x 10) + (6 x 1) = (5 x 100) + (2 x 10) + (12 x 1) - (2 x 100) + (4 x 10) + (6 x 1) = 500 + 20 + 12 - 200 - 40 - 6 = 286 This is the correct answer.

To avoid this mistake, you should always regroup or borrow when subtracting two numbers when the digit in the subtrahend is larger than the digit in the minuend in the same place value. You can also use a place value chart or base-ten blocks to help you visualize and perform regrouping or borrowing. For example:

#### Mistake: Not simplifying fractions

Simplifying fractions means reducing a fraction to its lowest terms by dividing both the numerator (the top number) and the denominator (the bottom number) by their greatest common factor (the largest number that can divide both numbers evenly). Sometimes, you may forget or ignore simplifying fractions when working with fractions. This will lead to incorrect answers and misunderstandings.

For example, consider this problem from Math Expressions Grade 4 Homework and Remembering Volume 2:

Write an equivalent fraction for: 8/12

If you do not simplify fractions, you may write any fraction that has the same value as 8/12 by multiplying or dividing both numbers by the same factor. For example: 8/12 = (8 x 2) / (12 x 2) = 16/24 8/12 = (8 x 3) / (12 x 3) = 24/36 8/12 = (8 x 4) / (12 x 4) = 32/48 However, these are not equivalent fractions in their lowest terms. According to simplifying fractions, you should divide both numbers by their greatest common factor, which is 4. This will give you: 8/12 = (8 / 4) / (12 / 4) = 2/3 This is an equivalent fraction in its lowest terms.

To avoid this mistake, you should always simplify fractions when working with fractions. You can also use a fraction bar or a number line to help you visualize and perform simplifying fractions. For example: 2/3 has a bar divided into three equal parts, with two parts shaded.">

#### Mistake: Not converting units of measurement

Converting units of measurement means changing a measurement from one unit to another unit of the same type or dimension. For example, converting inches to feet, or grams to kilograms. Sometimes, you may forget or ignore converting units of measurement when working with measurements. This will lead to incorrect answers and misunderstandings.

For example, consider this problem from Math Expressions Grade 4 Homework and Remembering Volume 2:

Amy's pencil is 18 centimeters long. Ben's pencil is 7 inches long. Whose pencil is longer?

If you do not convert units of measurement, you may compare the numbers without considering the units. For example: 18 > 7 Amy's pencil is longer. However, this is incorrect. According to converting units of measurement, you should change both measurements to the same unit before comparing them. One possible way to do this is to use a conversion factor, which is a fraction that shows the relationship between two units. For example: 1 inch = 2.54 centimeters 1 centimeter = 0.39 inches To convert Ben's pencil from inches to centimeters, we can multiply by the conversion factor that has centimeters in the numerator and inches in the denominator. This will give us: 7 inches x (2.54 centimeters / 1 inch) = 17.78 centimeters To convert Amy's pencil from centimeters to inches, we can multiply by the conversion factor that has inches in the numerator and centimeters in the denominator. This will give us: 18 centimeters x (0.39 inches / 1 centimeter) = 7.02 inches Now we can compare the measurements in the same unit and see that: 17.78 > 18 Ben's pencil is longer.

To avoid this mistake, you should always convert units of measurement when working with measurements that have different units. You can also use a ruler or a scale to help you measure and convert units of measurement. For example:
