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…
This is a super easy, super fun activity to tie art in with bilateral (mirror) symmetry. These are some samples of third and fourth grade work. CCSS: 4.G.3
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…
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. .
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…
