Math: 2019-2020

STEM + Multicultural Integration = STEMM!

The components of STEM (science, technology, engineering design and math) are by nature centered around the history, culture, curiosities and challenges of people from across the globe and time periods. Since the beginning of time people have used science, technology, engineering and design and math to analyze, explain and enhance the comings and goings of their communities.

The integration of cultural studies into our look at STEM components serves to broaden student perspective and global awareness thus preparing students to be creative, innovative, culturally aware 21st century citizens and leaders.

2nd Grade Gifted MATH COMPONENTS

DYNAMATH Supplemental Monthly Periodical: The Dynamath periodical provides cross-curricula exploration and integration of how math is used in current events around the world including non-fiction text features, geography and supplementing math skills.

NOETIC Math Competition: The International NOETIC Math Competition develops critical thinking skills, problem solving, reading and solving word problem strategies.

Students explore Common Core Standards and Objectives in the following domains:

FIRST SEMESTER

Numbers and Base Ten
Extending student understanding of the base-ten system including counting in fives, tens, and multiples of hundreds, tens and ones. This study also includes number relationships involving these units, including comparing and ordering numbers. Students understand multi-digit numbers (up to and beyond 1000) written in base-ten notation, recognizing that the digits in each place represent amounts of thousands, hundreds, tens or ones. Throughout the semester, students compare the Hindu Arabic base ten system with other ancient math systems including the ancient Chinese number system, the Roman numerals system, the ancient Mayan number system.

Operations and Algebraic Thinking
Students use their understanding of addition to develop fluency with addition, subtraction, multiplication and division within 100. Students also solve word problems by applying their understanding of models for addition, subtraction multiplication and division.

SECOND SEMESTER

Measurement and Data
Linear Measurement: Student recognize the need for standard units of measure and use rulers and other measurement tools with the understanding that linear measure involves an iteration of units. They recognize that the smaller unit, the more iterations they need to cover a given length.

Measuring Time: Beginning with the Earth’s revolution and rotation around the sun, students explore how that movement results in how we measure the passing of time in years, seasons, months, weeks, days, hours and minutes as well as how the passing of time has been the source of cultural celebrations, stories and holidays. Students explore measuring time using the Chinese lunar calendar based on the cycles of the moon and solar calendars based on the rotation and revolution of the earth around the sun, Students also explore instruments that measure time such as sand times, stopwatches, timers, analog and digital clocks.

Money: Students solve word problems involving dollar bills, quarter, dimes, nickels, and pennies.

Data: Students survey and create class data, draw picture,pie, bar and line graphs to represent a data set with up to four categories.

Geometry: Students recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces. Students Identify polygons including triangles, quadrilaterals, pentagons, hexagons and cubes. Study also includes finding perimeter and area of regular polygons. Students begin our study of geometry by looking at architecture and design from various cultures around the world including the Ndebele African tribe’s traditional use of geometric shapes on the outside of their homes. Students also look at the design and the use of geometric shapes in country flags around the world as well as the cultural meanings behind flag designs and colors.
