Math is GREAT!  This year we have a new math series called Math Investigations. 

^{Investigations is based on experience from research and practice, including field testing that involved documentation of thousands of hours in classrooms, observations of students, input from teachers, and analysis of student work. As a result, the curriculum addresses the learning needs of real students in a wide range of classrooms and communities. The investigations are carefully designed to invite all students into mathematics – girls and boys; members of diverse cultural, ethnic, and language groups; and students with a wide variety of strengths, needs, and interests.}

^{Based on this extensive classroom testing, the curriculum takes seriously the time students need to develop a strong conceptual foundation and skills based on that foundation. Each curriculum unit focuses on an area of content in depth, providing time for students to develop and practice ideas across a variety of activities and contexts that build on each other. Daily guidelines for time spent on class sessions, Ten Minute Math (3-5) reflect the commitment to devoting adequate time to mathematics in each school day.}

Parents & Students: This handbook is used in class, through a paper copy, as well as this online version for use at home. Use it as a reference for classwork, homework, and while playing math games.  Parents:  Since Investigations doesn't necessarily use the strategies that you and I were taught when we were in school, please use this handbook as a reference and guide to the math that your child is doing in class as well as the strategies being taught.

Factors, Multiples, and Arrays:  Workbook pages

Unit 1:  Factors Multiples and Arrays:  In this first unit in the multiplication and division strand, students deepen their understanding of the operation of multiplication. Students use rectangular arrays to represent the relationship between factors and multiples, use what they know to solve problems that increase in size, and focus on solving problems efficiently. They continue to develop fluency with multiplication combinations (facts up to 12 x 12).      

Unit 2:  Describing the Shape of the Data: Data Analysis:  This unit develops ideas about collecting, describing, and representing data. Students collect data through counting and measuring and use bar graphs and line plots to represent their data involving one group and compare data of two groups. They interpret the data and draw conclusions based on the data using terms such as mode, median, range, and outlier.

Unit 3: Multiple Towers and Division Stories:  Students develop strategies for solving multiplication problems with two-digit numbers and deepen their understanding of the operation of division by focusing on the relationship between multiplication and division. Using story contexts and multiple towers, students continue their investigation of the relationship between numbers and their factors. Students practice multiplying by 10 and multiples of 10, break problems into smaller parts that can be multiplied easily, and find the multiples of two-digit numbers. They gain fluency with all multiplication combinations to 12 x 12. Students solve, represent, and discuss division story problems, including some that have remainder.

 Unit 4: Size, Shape and Symmetry:   This first geometry and measurement unit focuses on classifying two dimensional shapes, comparing the size of angles, and working with linear and area measurement. Students define and categorize polygons by identifying sets of shapes that have a common attribute and use 90 degrees as a reference for finding the measurement of other angles. They continue their measurement work from earlier grades by measuring distance and perimeter, using both U.S. and metric units and finding the area of polygons in square units. It allows students to explore geometrical relationships, especially focusing on angle, length, and perimeter, patterns in sides and angles, and characteristics of specific shapes.

Unit 5: Landmarks and Large Numbers  Students extend their knowledge of the number system by examining the structure of 10,000 and practice and refine strategies for adding and subtracting whole numbers up to 10,000. They continue to study place value by adding and subtracting multiples of 10 and 100 to numbers in the thousands, and they consolidate their understanding of the operation of addition by studying a variety of addition strategies and algorithms, including the U.S. algorithm for addition. Students continue their study of subtraction by solving, representing, and discussing their strategies for a variety of subtraction problems

Unit 6: Fraction cards and Decimals Squares    Students develop ideas about fractions by identifying fractions of an area (3/4 of a rectangle), fractions of a group of objects (3/4 of 24), and decimal fractions (.75). They compare fractions of different wholes (1/3 of a 6 x 4 rectangle and 1/3 of a 10 x 10 rectangle), and combine fractions using models and reasoning. Students use 10 x 10 grids to represent, compare, and combine common decimals in the tenths and hundredths.

Moving between Solids and Silhouettes

 Unit 7:  Moving between solids and silhouettes:  Students examine the relationships between 3-D solids and their 2-D representations. They learn and use the mathematical terminology for these solids and their attributes. They translate between 3-D shapes and their 2-D representations as they build cube configurations from pictures and mental images and investigate silhouettes of solids from several different perspectives. Students build an understanding of measuring volume as they examine the structure of rectangular prisms and determine the number of cubes that fit inside given box patterns

Unit 8: How many Packages?  How many Groups?  In this last multiplication and division unit in Grade 4, students continue to develop efficient strategies for solving multiplication problems by breaking problems into smaller parts or changing one or both numbers to create an easier problem. Students also focus on recording their work with clear and concise notation. Students develop strategies for solving division problems (three-digit divided by two-digit), which involve making groups of the divisor. These problems are presented both in story contexts and numerically.

Basic Math Fact Worksheet:  Mad Math Minutes is a great way to practice basic math skills in addition, subtraction, multiplication, and division. You pick the number of and types of problems that you want to practice.
