## Grade 5 Overview: Fractions, Rounding and Data Analysis

In Grade 5, students start to combine familiar and new math skills for problem-solving. Happy Numbers includes many exercises with interconnection of different skills so that students learn to fluently operate their knowledge. You’ll also find tasks in which they can choose the next step in problem-solving, which reinforces their independence in math.

The curriculum covers general skills of working with fractions and decimals: addition and comparison of fractions with different denominators, solving word problems, long multiplication and division, finding a fraction of a number, extraction of the whole part and fractional part by long division, and a lot more. Students expand their skills of rounding (started in Grade 3) to decimal fractions. They discover fractions as division and master fraction reduction. This leads to expanding their knowledge with fraction division and grasping the connection between division by a fraction and multiplication by its denominator. In the meantime, they have much work to do with place value, including working to the thousandths place.

Moreover, students develop the skill of translating word problems into mathematical notation. They advance to more complex composition and analysis of data including engaging tasks with line plots, which is perfect practice for data analysis. In addition, they become familiar with the concept of an exponent and build fluency with powers of 10.

Sounds heavy? Not at all, if there is a teacher and a good digital assistant! Explore the Happy Numbers Grade 5 curriculum with this overview and its concrete examples and pedagogy notes. Use of multiple representations, manipulatives, and interactive exercises with an opportunity to choose the next steps can make your lessons more interesting and effective!

## Decimal Fractions

#### Introduction of Thousandths

Happy Numbers introduces thousandths by the familiar model of the Place Value Chart. Students can drag disks through the chart and get a tangible experience of the number composition. In addition, they complete patterns in the word form to build a complex understanding of this new concept.
