Multiplication Arrays with Stickers, Rubber Stamps and Dice

Multiplication Arrays with Stickers, Rubber Stamps and Dice

Super easy way to have 2nd or 3rd graders physically make each of the multiplication facts. They roll two dice (two different colors, one color for rows and the other color for columns) and create the array using stickers or rubber stamps. Sometimes having them use graph paper helps keep the rows and columns lined up. Also, since a regular die only goes up to 6, you can use dice that has 10 faces. Another options would be to cover…

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…
