I use the following materials for my unit on angles. Scouring the internet to put these items together to engage your students can be a pain. Hopefully, if you’re a 5th grade teacher, this can be your one-stop-shop. I’ve listed the online resources that I use in my classroom (in the order that I use them) below.
Triggering Prior Knowledge/Review
Before the start of our unit on angles, I ask students to label two pages in their notebooks “Angle Review”. We tape this table (pictured right) onto the second page. For homework, students review the Powerpoint (posted to Kidblog), copy the definitons and angle from Slide 2, and complete the table from Slide 3 of the Powerpoint.
Here is a fun video I like to share to kick off the unit. The kids love it!
Primary focus: Measuring Angles with a Protractor
Math Playground has designed a program that allows students to practice using a protractor and measuring angles online. Click here or on the image to try it out yourself. I particularly like that students are given immediate feedback and are able to remeasure and correct their answers. I use this activity along with the others listed in this section at a math station for extra practice after our first lesson in the angles unit.
Alien Angles is another game by Math Playground. In this game, students must rescue some friendly aliens. The computer will generate a launch angle, and for students to successfully rescue the aliens, they must estimate the launch. Students adjust the angle to launch a rescue ship in the correct direction. Their estimate must be within 5˚ of the degree specified in order to successfully rescue the friendly alien. My class always has a good time with this one.
Primary focus: Estimating Angles
This “Star Gazing” game from PBS Kids challenges students to locate eight planets by estimating the angle needed to point the telescope in their direction.
Primary focus: Drawing Angles
This is a fantastic online resource for drawing angles. Students are given an angle and must line up the protractor and adjust the arms of the angle to create the angle requested. When students are ready, the click “check answer” and receive immediate feedback. I ask my kiddos to solve 5 problems correctly before advancing to the next activity. Each activity increases in difficulty.
Note: You need Java to access this activity.
Sum of Angles in Triangles and Quadrilaterals
Primary Focus: Reinforce sum of angles in triangles and quadrilaterals.
This is a manipulative that allows students to adjust the angles in various geometrical shapes. Students are able to see that regardless of the angles adjustments, the sum of angles is always the same.
Primary Focus: Students must apply the various rules for finding unknown angles.
This is a one or two person game. I like this game because it requires students to apply the various rules learned about angles to find the unknown angle: supplementary angles, vertically opposite angles, sum of angles in a triangle.
Primary Focus: Classify different types of quadrilaterals.
Before learning the the sum angles in a quadrilateral, we first review quadrilaterals. Students need to know the different types of quadrilaterals and how to identify them. This game is great for review and practice.
This is an easy practice activity. An angle in either a triangle or quadrilaterial is missing and students must find the unknown angle by adding the known parts together and subtracting from the appropriate sum of all angles (180˚ or 360˚). If students answer a question incorrectly, they receive a detailed explanation to resolve it correctly. Note: Students can solve 20 problems without an IXL account. Therefore, this activity should not be used at a station with a shared computer.
This an a fantastic interactive review activity for your 5th grade angles unit. This BBC types of angles, finding an unknown angle in a complete rotation or a straight line, Using sum of angles to find an unknown angle, finding unknown angles in a traingle, finding unknown angles in an isosceles triangle, equilateral triangles, angles in a quadrilateral. Note: Java required.
If you find a dead link, please let me know. Clicking on a link that leads you nowhere or to a dead site is the pits! I’d like to keep this as a reliable resource.
