Common Core State Standards in Mathematics – Geometry

Comments 0 Comment

Why give students the definitions? Why not give them enough information so that they can create the definitions on their own? The Common Core state Standards in Mathematics along with the National Council of Teachers of Mathematics Standards emphasize allowing students to be actively involved in creating their learning. Through this, they will learn to: -reason abstractly and quantitatively -construct viable arguments and critique the reasoning of others -attend to precision -look for and make use of structure Besides, the…

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…

Math Around Us: Parallel Lines

Math Around Us: Parallel Lines

One of the best ways to teach students geometry vocabulary is to simply look around our environment. For example, if you want students to understand parallel lines, pair them up and hand them an individual white board and take a stroll around the school. Have them write down all the parallel lines they see. Here are two examples of parallel lines in our environment. Check out all the parallel lines in the door, the windows, the bookshelf, even the light…
