Hunting for Buried Treasure: Angles and Angle Measurement

Hunting for Buried Treasure: Angles and Angle Measurement

Comments 0 Comment

Aye, matey, it’s time to hunt for buried treasure. In this fun and creative activity, students will be designing their very own treasure map. As they design their map and hide their treasure, students will get plenty of practice using a protractor while reinforcing mathematical vocabulary such as acute, obtuse, and right angles, parallel and perpendicular lines. Tying in social studies and writing skills, students will be using a compass rose to write directions in order for their classmates to…

Identify, Describe, Analyze, Create, and Reason with Shapes and their Attributes

Here’s something super easy to do with kindergartners and first graders that covers a lot of the Common Core geometry standards. You will need one geoboard per student and some geobands. Working in small groups, ask students to design different shapes on their geoboards. Discuss the attributes of the shapes and compare different shapes such as rectangles and triangles. Next, have students create different shapes within specific parameters. For example, design a triangle that touches exactly 4 pegs. See photo…

We’re surrounded by line segments. These line segments create parallel and perpendicular lines, and acute, obtuse and right angles. Looking for them in our environment is a great way to reinforce them. Ask your kids: Who can find a set of parallel lines? …perpendicular lines? …an acute angle? Pretty soon, they’ll be seeing nothing but lines and angles in the tiles on the floor, the branches of the trees, the way an ice hockey puck hits the wall… For older…

Project-based Learning: Soda Can Redesign, a Lesson on Volume

Project-based Learning: Soda Can Redesign, a Lesson on Volume

Comments 0 Comment

This is a fun lesson I do with sixth graders where students redesign the soda can. After reviewing volume of rectangular prisms, students determine the volume of a can of soda in cubic inches. They use this volume to re-design the soda can so that their can has the same volume. Students will need to use the area of polygons such as rectangles, triangles, parallelograms, and trapezoids in the design of their new can. They begin by creating a net…

CCSS: Teaching Area in Third Grade

CCSS: Teaching Area in Third Grade

Comments 0 Comment

My son came home with this project in the third grade and I thought it was brilliant! But then, I was reminded of his third grade teacher, Mrs. Durbin, and it made sense. She understands how to teach mathematics effectively and is always doing fun, hands-on activities and projects with her students. For this project, Mrs. Durbin was working with her students on the concept of area. Students created a design on inch graph paper and then indicated the total…
