 ### Fifth Grade Math

Our math curriculum supports all students in acquiring mathematical knowledge and skills, and the confidence to become active learners who can reason about and represent mathematical ideas and relationships. Grade 5 mathematical topics cover the broad mathematical areas of: whole number place value and number theory, whole number multiplication and division, adding and subtracting fractions and mixed numbers, multiplying and dividing fractions and mixed numbers, decimal place value and operations, 2-D geometry focusing on properties of triangles and four-sided figures, 3-D geometry focusing on volume, and algebra through growing patterns and graphing. We draw primarily on the TERC Investigations 3rd Edition as well as Math in Focus resources to support our teaching of the Common Core content and mathematical practices.

Our work in fifth grade will focus on three critical areas:

1. developing fluency with addition and subtraction of fractions, and developing understanding of the multiplication of fractions and of division of fractions in limited cases (unit fractions divided by whole numbers and whole numbers divided by unit fractions)

2. extending division to 2-digit divisors, integrating decimal fractions into the place value system and developing understanding of operations with decimals to hundredths, and developing fluency with whole number and decimal operations

3. developing understanding of volume

Throughout the units of study, students will develop content understanding concurrently with Common Core Math Practice Standards. These practice standards require students to understand concepts deeply and use higher order thinking skills to communicate their ideas clearly.

Specifically, students will work on eight skill areas:

• Making sense of problems and persevering in solving them
• Reasoning abstractly and quantitatively
• Constructing viable arguments and critiquing the reasoning of others
• Modeling mathematically
• Using appropriate tools strategically
• Attending to precision
• Looking for and using structure
• Looking for and expressing regularity in repeated reasoning

Finally, we spend time each week in Adventure Math tackling interesting and tough math challenges that allow students to experience the adventure and excitement of solving problems. looking for patterns, making meaningful decision and discoveries. Developing strong teamwork skills is an important aspect of this project.
