Exploring Volume: A FREE Hands-On Activity

I feel like I’ve been filling my blog with so many geometry activities lately, and today will be no exception.  #sorrynotsorry  This is seriously one of my favorite units.  This week, we were finally ready to dive into three-dimensional objects! I partnered up my students, passed out a handful of blocks, and gave them a shape to cut out.  Even though we were working in groups of two, we all had the same shape.  I wanted to explore what volume was, and how to calculate it with a common example. After filling their shape with cubes, I asked them to…

Using Nets to Find Surface Area: A Free Math Activity

Why does surface area have to be so intimidating?  My kids are excellent at calculating the areas of squares, rectangles, and triangles.  Buuuuuut, the second you throw multiple parts and pieces together, it becomes instantly overwhelming.

They folded up their shapes, and named the solid figure that they had created. Then, they assigned a measurement or measurements to their shapes. Students with more complex shapes loved the opportunity to…

Area of a Triangle: Discovering the Formula

My area and perimeter unit is seriously one of my favorite things to teach in fifth!  I love the formulas, the real life math experiences, and the hands on learning that can happen.  This week, I did a simple, yet totally powerful demonstration to help my students discover, and most of all remember, the formula for the area of a triangle. I gave each student a 5 inch by 5 inch square.  We used our rulers to measure five rows and five columns to show the area of our square. Last year, I used a 4 inch by 4 inch…

Unwrap a Gift from ME!

I am going to make a crazy generalization here and say that you have about two weeks left before Christmas Break and you are EXHAUSTED with a HUGE list of things you’d like to get done before break…..am I close?  Now, I can’t make the to-do list disappear, but I can help provide you with a super fun set of brain teasers that my kids enjoyed for FREE! I truly love blogging, chatting, statusing (….will that be added to Webster’s Dictionary soon?), and sharing with you all!  I have loved the resources, ideas, and support that I have gotten from…
