Sierpinski Triangle: A Family Math Night Fractal Activity

Sierpinski Triangle: A Family Math Night Fractal Activity

    Here’s a fun Family Math Night collaborative project where participants create a Sierpinski Triangle. The project includes three activity levels all which result in creating self-similar triangles which are them put together to make the large Sierpinski Triangle. I also talk about the Father of Fractal Geometry, Benoit Mandlebrot, Chaos Theory, and the connection between fractals and our cell phones. Click on the image to the left to get the lesson plan. .

Family Math Night ‘What Do You Notice?’ Poster

Family Math Night ‘What Do You Notice?’ Poster

As I was thinking about my ‘What Do You Notice?’ poster for my Nifty Numbers Family Math Night event last night, it seemed natural to tie it in with numbers. So here’s the poster I created. As with all my ‘What Do You Notice’ posters, they can be “answered” on a variety of levels. This one can go all the way to algebraic equations. And that’s what makes them so much fun. Everyone can do them! What I loved about…

Family Math Night ‘What do you notice’ Posters

I love the idea of having at least one What do you notice? posters at our Family Math Night events.   I started it last year when I did an event at an IB school and the two teachers I was working with wanted to tie in some of the IB inquiry philosophy.  It was really fun to watch the kids standing in front of the posters trying to ‘notice’ things.  Besides, they got an extra Estimation Jar slip for…

Set Model of Multiplication

Set Model of Multiplication

This is an easy activity to do with students that shows the set model of multiplication: number of groups x number of objects in each group. Students (or the teacher) chooses the number of groups/circles to work with. Then they choose how many they want in each group and use stickers, rubber stamps or actual object to place in each circle. Students can glue their circles onto construction paper and record the multiplication equation underneath. Makes a great bulletin board!…
