## UOI 3: How The World Works

**Transdisciplinary Theme:**

An inquiry into the natural world and its laws; the interaction between the natural world (physical and biological) and human societies;** how humans use their understanding of scientific principles; the impact of scientific and technological advances on society and on the environment.**

**Central idea:** Engineers innovate to solve problems.

**Key concepts**: causation, form, connection

**Related concepts:** patterns, cause & effect, cycles, engineering, inventions

**Lines of inquiry**

- The need for inventions (Causation)
- The design cycle (Form)
- The impact of design and technology on daily life (Connection)

## UOI Field Trip - Maryland Science Center on February 1, 2018

Students will need to wear their formal uniform and have a brown bag lunch (more details and permission slips will be sent home in the coming weeks).

Students will be attending **The Engineered by Design **enrichment program at the Maryland Science Center. They will further explore the engineering design process, and be challenged to follow the design process in order to design a solution for a given task.

The students will also watch **Dream Big**, an IMAX film, in which engineering will be discussed as a heroic and creative field. They will also learn about young engineers that have created life-saving and world-altering marvels. This film will inspire the students to become the innovators of the 21st century.

## What Are We Learning This Unit?

## Math

Students begin to conceptualize area as the amount of two-dimensional surface that is contained within a plane figure. They come to understand that the space can be tiled with unit squares without gaps or overlaps (3.MD.5). Students decompose paper strips into square inches and square centimeters, which they use to tile 3 by 4, 4 by 3, and 2 by 6 rectangles. They compare rectangles tiled with like units and notice different side lengths but equal areas. Topic A provides students’ first experience with tiling from which they learn to distinguish between length and area by placing a ruler with the same size units (inches or centimeters) next to a tiled array. They discover that the number of tiles along a side corresponds to the length of the side (3.MD.6).

Students progress from using square tile manipulatives to drawing their own area models. Anticipating the final structure of an array, they complete rows and columns in figures such as the example shown to the right. Students connect their extensive work with rectangular arrays and multiplication to eventually discover the area formula for a rectangle, which is formally introduced in Grade 4 (3.MD.7a).

Students manipulate rectangular arrays to concretely demonstrate the arithmetic properties in anticipation of the lessons that follow. They do this by cutting rectangular grids and rearranging the parts into new wholes using the properties to validate that area stays the same, despite the new dimensions. They apply tiling and multiplication skills to determine all whole number possibilities for the side lengths of rectangles given their areas (3.MD.7b). These activities create an opportunity for students to solve problems involving area (3.MD.7b). Students decompose or compose composite regions, such as the one shown to the right—into non-overlapping rectangles, find the area of each region, and then add or subtract to determine the total area of the original shape. This leads students to find the areas of rooms in a given floor plan (3.MD.7d).

**Purple Group**

Students extend and deepen Grade 2 practice with equal shares to understanding

fractions as equal partitions of a whole (2.G.3). Their knowledge becomes more formal as they work with area models and the number line. Throughout the module, students have multiple experiences working with the Grade 3 specified fractional units of halves, thirds, fourths, sixths, and eighths. To build flexible thinking about fractions, students are exposed to additional fractional units such as fifths, ninths, and tenths.

Students begin this module with actively partitioning different models of wholes into equal parts (e.g., concrete models and drawn pictorial area models on paper). They identify and count unit fractions as 1 half, 1 fourth, 1 third, 1 sixth, and 1 eighth in unit form. In Topic B, students are introduced to the fraction form (3.NF.1) and understand that fractions are numbers. Just like any number, they can be written in different forms.

Students compare and make copies of unit fractions to build non-unit fractions. They understand unit fractions as the basic building blocks that compose other fractions (3.NF.3d), which parallels the understanding that the number 1 is the basic building block of whole numbers (e.g., 1 and 1 and 1 make 3 just as 1 third and 1 third and 1 third make 1). In Topic C, students practice comparing unit fractions using fraction strips. They

specify the whole and label fractions in relation to the number of equal parts in that whole (3.NF.3d).

Students then transfer their work to the number line. They begin by using the interval from 0 to 1 as the whole. Continuing beyond the first interval, they partition, place, count, and compare fractions on the number line (3.NF.2a, 3.NF.2b, 3.NF.3d). Next, they notice that some fractions with different units are placed at the exact same point on the number line, and therefore, are equal (3.NF.3a). For example, 1/2, 2/4, 3/6, and 4/8 are equivalent fractions (3.NF.3b); they are different ways of naming the same number.

Students recognize that whole numbers can be written as fractions, as exemplified on the number lines to the left (3.NF.3c). The module concludes with comparing fractions that have the same numerator. As students compare fractions by reasoning about their size, they understand that fractions with the same numerator and a larger denominator are actually smaller pieces of the whole (3.NF.3d). These activities leaves students with a new method for precisely partitioning a number line into unit fractions of any size without using a ruler.
