## Math

Note: The outline and order shown here is to help you get a general idea of what we learn in fifth grade. However, please be aware that the exact topics, order and materials used may vary in order to best meet the needs of the 5CK learners.

Welcome to 5CK Math! Please note that students are assigned different math classes. Be sure to look for homework listings, announcements and other information that’s specific to 5CK Math if your learner has Mr. Cook for math.

Also please note that the exact order of missions and lessons is subject to change. Some lessons are also skipped.

Below is a brief outline of the math missions for fifth grade along with these resources:

• Homework Helpers: A good place to start if you’re stuck on homework. Please note we do not have versions for the latest editions of our math program, so there may be cases where there are slight differences.
• Tip Sheet: An illustrated guide to help you understand math concepts quickly.
• Homework: All homework pages for each module. This is helpful if your learner accidentally leaves his or her binder at school. You can download the file, find the lesson you need and print those pages for your learner to complete.

5CK Math uses these online learning tools:

### Mission 1: Place Value with Decimal Fractions

This opening Mission is a culmination of 2nd, 3rd and 4th grade. Additionally, students extend their understanding of decimal fractions to the thousandths place and more sophisticated patterns of our base ten system.

### Mission 2: Base Ten Operations

Mission 1 introduced students to decimal fractions, and Mission 2 will introduce them to similar conceptual work (mental math, reasoning, conceptual models, and algorithms), but with whole numbers. Students will multiply multi-digit whole numbers in the first part of the Mission and divide them in the end. Each operation concludes with application work and measurement word problems.

### Mission 3: Add and Subtract Fractions

In this Mission, students will develop flexibility with addition and subtraction of fractions so they can mentally or numerically solve, reason, and estimate their calculations. The Mission begins with concrete and pictorial work (using area models and number lines) and moves to numeric work with word problems by the end.

### Mission 4: Multiply and Divide Fractions and Decimals

Students tackled equivalency in adding and subtracting fractions in Mission 3, and now they’re ready to focus on multiplying and dividing fractions. Their understanding will be deeply rooted in multiple concrete examples and pictures before they generalize to more abstract methods.

### Mission 5: Volume, Area and Shapes

This mission kicks off with a deep focus on cubic units and counting them to find area. Students will look for efficient ways to count and derive the formula for volume! The second half of the mission asks students to apply their understanding of multiplying and dividing fractions (from Mission 4) to determine area.

### Mission 6: The Coordinate Plane

We build on students’ familiarity with a number line to construct an understanding of a coordinate system. With this new understanding, students explore relationships between points, patterns, and the rules that generate lines. Ultimately students connect this exploration to real world applications.
