Money Jars

Money Jars

Learning to save money is an important life skill. During America Saves Week (February) or Financial Literacy Month (April), I like to have small groups of students rotate through the Money Jar Center. I’ve also done it as a whole class activity with second grade and up. Students do have the option of using a hot glue gun. I go over the rules very carefully. Even so, there are usually a handful who choose not to use the glue gun….

Project-Based Learning – Target Practice: Teaching the Area Formula for a Circle

Project-Based Learning – Target Practice: Teaching the Area Formula for a Circle

Meaningful math with a purpose! This great hands-on lesson gets students doing math while designing targets. Students become comfortable using the area formula for circles. And the best part is, their targets are set up and used during the school’s fall carnival. Watch the video below for the entire lesson plan. CCSS: 7.G.4 TEKS: 6th grade 6C, 8A, 8B Link to video. .

The Artistic Side of Math – Area

The Artistic Side of Math – Area

This is one of my favorite math and art activities. That’s because it involves a mathematical pattern. Using centimeter graph paper, we start with the basic unit which, in this case, is simply one square. I then ask students what they think the area would be if we doubled the size of the square. The first thing they blurt out before thinking is “two”. I then use the graph paper to show them that if I double the square (double…

3-D Geometry

3-D Geometry

Kids love geometry. It’s so hands-on. At least, it should be. I can’t imagine trying to teach kids geometry without letting them draw, cut, design, build. 3-D geometry taught on paper? I don’t think so! Unless, of course, you’re designing nets. And that’s exactly what I did with a group of sixth graders. We were working on volume and I thought it would be fun to re-design the soda can. It required a lot of hands-on work that involved graph…

Beginning Multiplication: Circling Multiples

Beginning Multiplication: Circling Multiples

Here is a super easy activity to do with student who are learning multiplication. I use patterned paper or wrapping paper cut into 8.5 x 11. I place them in sheet protectors and students use wet erase markers to circle groups of a given number. In this example, groups of 4 are being circled. Then students write the equation. An example could be: 4 x 8 = 32. This is a great activity for younger students who are learning to…
