Halloween Bilateral Symmetry Art Project: CCSS 4.G.3
Super simple, and super fun. Great way to introduce bilateral/mirror symmetry. I usually do this with fourth graders but I think third graders could probably do it, too. CCSS: 4.G.3
The Artistic Side of Math – Line Design
I love asking my upper elementary students to draw a curved line using only straight lines that are at least five inches in length. It stumps them. And that’s part of the fun. Because now I get to show them how to do it! This is a super easy lesson and great to keep in their desks to work on when they finish other work. Mounted on black construction paper, these look awesome on a bulletin board. Students use a…
Teaching Polygons Using Rubber Bands
Here’s a super easy and fun way to reinforce attributes of polygons. Using a rubber band that is not too small or thick, students create shapes using their fingers. It’s a great multi-sensory activity. Ideas: -show me a triangle -show me a triangle with one obtuse angle -show me an iscoceles triangle -show me a quadrilateral -show me a trapezoid -etc. Shapes larger than a quadrilateral (4 sides) are more difficult to make. Students can partner up to make pentagons…
Multiplication of Fractions. What Does it Mean?
So that’s what it means to multiply fractions! Visual representations make all the difference! I acutally have students first do this using a geoboard. Then we transfer to grid paper (see above photo). After collecting a number of samples, students look for patterns and discover that multiplying across gives them the same answer. But now it makes sense! CCSS: 5.NF.4; 5.NF.5
Sum of Interior Angles of Triangles
This is a super easy, super fun activity where students discover the interior angle measurements of different polygons. I start with the triangle (see photo) and then have them work in groups to prove other interior angle measurements. Collaboration and communication in the math classroom is so important and this is an easy way to do it. Teams can then do a 1-2 minute presentation which helps develop their public speaking skills.
