Family Math Night What Do You Notice? Poster

September 27, 2015 Karyn Comments 0 Comment

Here’s my latest What Do You Notice? poster from a recent Family Math Night event. The nice thing about these posters is that they’re open-ended which allows for anyone to respond. For this one, I decided to make a venn diagram. But I didn’t draw the usual circles. Instead I drew two hexagons. This created the rhombus (parallelogram) in the center. The categories I used for the numbers were even numbers and multiples of 5. That said, anything appropriate would have…

When that die settles, a quick glance tells you…

One of my goals for the beginning of the new school year was to get my students excited about math from the moment they walked in the door. To do this I started our math lessons in the area (no pun intended!) of geometry through hands-on activities and projects. I discovered that through allowing kids to design, create, and build – something all kids love – I could sneak in important ideas in math. But the other thing I discovered…
