Mrs. Walls' Math Blog (Week of 4.29.19)We will begin Chapter 11: Geometry and Fraction Concepts. In this chapter, students will learn about three-dimensional and two-dimensional shapes. They will also learn about equal parts of a whole.Lessons this week include identifying three-dimensional shapes, identifying and describing three-dimensional shapes according to the number of faces, edges, and vertices, building three-dimensional shapes using cubes and other objects, naming 3-, 4-, 5-, and 6-sided shapes according to the number of sides and vertices, and identifying angles in two-dimensional shapes. Why teach this?A tally chart provides an efficient way to record data collected in a survey. One tally mark is made in the chart for each response given in the survey. There is, therefore, a one-to-one correspondence between responses and tally marks. Every fifth tally mark is made as a diagonal mark over the four preceding marks. This convention makes it easier to count by fives instead of ones to find a total. Children use a variety of skills as they read and interpret data in a picture graph. THey must first be able to read and understand the elements of a picture graph: the title, the categories, the key, and the pictures indicating the data contained in the graph. Once children understand how to read a picture graph, they will then be able to find and use information in the graph to answer questions and solve problems. Children will solve problems involving addition and subtraction. In this chapter, the keys for the picture graphs are limited to pictures that represent one unit. THe use of a key builds a foundation for using keys in which each picture represents multiple units, which are taught in later grades. Chapter 11 Vocabulary-For each chapter, I will be providing a list of important vocabulary words related to our in class learning. Developing student's math language is a great way to improve their problem solving skills (think of complex word problems!). **angle-**a shape formed by two line segments that share the same endpoint**cone-**a three-dimensional shape with a circular base and a point at the top**cube-**a three-dimensional shape with six square faces**cylinder-**a three-dimensional shape with two circular parallel bases and a curved surface**edge-**where two faces of a three-dimensional shape meet**face-**a polygon that is a flat surface of a three-dimensional shape**fourths-**four equal parts**halves-**two equal parts**hexagon-**a polygon with six sides**pentagon-**a polygon with five sides**quadrilateral-**a polygon with four sides**rectangular prism-**a three-dimensional shape with six faces that are rectangles**side-**one of the line segments that forms a polygon**thirds-**three equal parts**vertex-**the point where 2 sides of a polygon meet or 3 or more edges of a three-dimensional shape meet
