Unit 5 Standards
Reason with shapes and their attributes.
MGSE2.G.1 Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces. Identify triangles, quadrilaterals, pentagons, hexagons, and cubes.
MGSE2.G.2 Partition a rectangle into rows and columns of same-size squares to find the total number of them.
MGSE2.G.3 Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape.
Represent and interpret data.
MGSE2.MD.10 Draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories. Solve simple put-together, take-apart, and compare problems using information presented in a bar graph.
OVERVIEW
In this unit students will cultivate spatial awareness by:
• further developing understandings of basic geometric figures
• identifying plane figures and solid figures based on geometric properties
• describing plane figures and solid figures according to geometric properties
• expanding the ability to see geometry in the real world
• partitioning shapes into equal shares by cutting, slicing, or dividing
• represent halves, thirds, and fourths using rectangles and circles to create fraction models
• compare fractions created through partitioning same-sized rectangular or circular wholes in different ways
• understand what an array is and how it can be used as a model for repeated addition
• organize and record data using tallies, simple tables and charts, picture graphs, and bar graphs
Students describe and analyze shapes by examining their sides and angles. Students investigate, describe, and reason about decomposing and combining shapes to make other shapes. Through building, drawing, and analyzing two- and three-dimensional shapes, students develop a foundation for understanding area, volume, congruence, similarity, and symmetry in later grades.
Although the units in this instructional framework emphasize key standards and big ideas at specific times of the year, routine topics such as counting, time, money, positional words, patterns, and tallying should be addressed on an ongoing basis through the use of calendar, centers, and games.
To assure that this unit is taught with the appropriate emphasis, depth, and rigor, it is important to study the tasks in this unit early in the planning process. The tasks in this unit illustrates the types of learning activities that should be utilized from a variety of sources in order for students to gain a solid foundation in geometry to meet or exceed grade level standards.
