Grade 4 - Geometry Unit
Standards covered:
- 4.6 Geometry and measurement
-
4.6A
Identify points, lines, line segments, rays, angles, and perpendicular and parallel lines.
-
4.6B
Identify and draw one or more lines of symmetry, if they exist, for a two-dimensional figure.
-
4.6C
Apply knowledge of right angles to identify acute, right, and obtuse triangles.
-
4.6D
Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines or the presence or absence of angles of a specified size.
The Geometry Unit involves analyzing the defining attributes of 2-dimensional shapes and 3-dimensional solids in order to answer questions such as:
- What is the relationship between the sides of this shape/solid?
- How is this relationship used to define the shape/solid?
Summative Assessment Task
Given various clues, students determine which shapes can represent each set of clues.
Instructional Tasks/Formative Assessments
Using a set of clues, students determine what shapes will represent the clues and satisfy the answers to four questions.
Given the fair value of a square, students determine the fair values of at least three other shapes within the square.
Given first initial of five girls, students list the letters in order from the letter that has the least number of angles to the letter that has greatest number of angles.
Students determine which triangles and quadrilaterals Kyle can make with sticks and glue, and the total amount of time it will take to make all the shapes.
Using pentominoes, students determine which pentominoes will fit a series of clues.
The N/A classification refers to TEKS Standards that cannot be assessed through problem solving.
For this reason, tasks have not been included for these particular standards.
