Videos, examples, solutions, and lessons to help Grade 4 students learn how to use right angles to determine whether angles are equal to, greater than, or less than right angles.
Common Core Standards: 4.G.1
The following diagram shows a worksheet to distinguish between right, acute, and obtuse angles.
Problem 1: Creating right angles through paper folding activity.
Problem 2: Determine whether angles are equal to, greater than, or less than a right angle.
Problem 3: Draw right, acute, and obtuse angles. Lesson 2, Problem Set
1. Use the right angle template that you made in class to determine if each of the following angles is greater than, less than, or equal to a right angle. Label each as greater than, less than, or equal to, and then connect each angle to the correct label of acute, right, or obtuse. The first one has been completed for you. This video shows how to distinguish between the 3 types of angles: acute, right and obtuse.
Lesson 2, Problem Set
3. Construct each of the following using a straightedge and/or the right angle template that you created. Explain the characteristics of each by comparing the angle to a right angle. Use the words greater than, less than, or equal to in your explanations.
a. acute angle
b. right angle
c. obtuse angle Grade 4, Module 4, Lesson 2, Exit Ticket, Question 2
Use a right angle template to determine which of the following angles are greater than, less than, or equal to a right angle. (obtuse, acute, right or straight angles) Grade 4, Module 4, Lesson 2, Homework
1. Use the right angle template that you made in class to determine if each of the following angles is greater than, less than, or equal to a right angle. Label each as greater than, less than, or equal to, and then connect each angle to the correct label of acute, right, or obtuse. The first one has been completed for you.
2. Use your right angle template to identify acute, obtuse, and right angles within this painting. Trace at least two of each, label with points, and then name them in the table below the painting.
