Really, Texas? No calculators?

Really, Texas? No calculators?

I just read that the Texas State Board of Education is getting rid of calcuators in the elementary grades. It’s a good thing, too, because I’ve no doubt that every kindergarten through fifth grade teacher hands their students calculators so that these teachers can get out of doing what they love doing…teaching. Honestly. Although not approved yet, it’s only a matter of time. Because, as we all know, politicians know best. And, yes board members, you are politicians. I remember…

The Artistic Side of Math – Tessellations

The Artistic Side of Math – Tessellations

I love M.C. Escher! I have a whole book on his work and love to share it with my students when we’re studying angle measurement. That’s because we’re going to tie math and art together through modifying polygons similar to how M.C. Escher did it in some of his paintings. It’s all about tessellating shapes and angles. Using pattern blocks, I show students how shapes tessellate. See photo below. Then, I have students determine the angle measurement of each of…

The Two Most Important Questions to Ask Your Kids

The Two Most Important Questions to Ask Your Kids

Okay, so I’m talking about the two most important questions you can ask your kids to help develop mathematical thinking. Wait! Don’t go. Math often receives short shrift. It’s unfortunate because math, taught correctly, teaches us how to effectively problem solve. It’s also the perfect subject to teach our kids persistence. Research has shown that kids who are persistent tend to do better academically. And doing well academically has great benefits in life. The two most important questions: #1: WHY?…

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…
