Skip counting – Multiples of 2

Skip counting – Multiples of 2

Students use sticky dots to create a caterpillar with a head and 10 body parts. They add eyes, a mouth, and antennae to the head. Then they add two legs to each body part. Finally, they skip count by 2s and write in the number. For the younger ones, I provide a 0-110 number chart for them to use as they write in the numbers. . . . Oops…I didn’t catch this one in time. Her caterpillar is skip counting…

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….

The Artistic Side of Math – 180-degree Rotational Symmetry

The Artistic Side of Math – 180-degree Rotational Symmetry

Crossword puzzles are symmetrical?! That’s usually the response I get after students have been given a chance to look through blank crossword puzzles I’ve cut from the paper. Then I show them how all crosswords are designed with 180-degree rotational symmetry. Starting with 90-degree rotational symmetry, we rotate an object 1/4 the way around the circle. See photo below. Then we rotate an additional 90 degrees so that we end up with a turn of 180-degrees. (We’ve done work in…

There is No Math Gene

There is No Math Gene

Remember when I said there is no math gene? I meant it. But to underscore it, I’m going to share my son’s artwork. What does art have to do with math genes? Take a look at the photo. These are some of the art pieces that are hanging on my wall created by my oldest son. (My youngest son has an art wall, as well.) I’ll have to admit, these pieces are pretty good. The longboard piece (Gustave Caillebotte’s Paris…

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. .
