During a unit on 2-dimensional geometry I use art to tie in the polygons we’ve been studying. I share a variety of paintings by the artist Pablo Picasso and we talk about the shapes they see. Then, using the idea of straight lines and hard edges, students create their own work of Cubism out of construction paper.
Mathematics and nature often go hand-in-hand. In this lesson, students study the spirals of the nautilus and tie it in to a numerical sequence called the Fibonacci sequence. They use the sequence to re-design the nautilus using home-made compasses. I begin the lesson by showing the first few terms of the Fibonacci sequence and have students work together to see if they can figure out the pattern and the next few numbers in the sequence: 1, 1, 2, 3, 5,…
Ancient Africans in Egypt enlarged pictures by using nets of squares. In this fun project, students re-construct a smaller picture into a very large picture. In mathematics, we call this dilation which is a type of trasformation studied in geometry. This is an activity I do with fourth graders and above. I first begin with a picture that I know the students will have fun re-constructing. Hence…Sponge Bob. Depending on the number of students who will be working on one…
Partners traced each other’s feet. Then we used Unifix cubes to determine the area. (Partial squares got a little tricky but we did a little fraction work.) Then table teams grouped their Unifix into tens and ones for some place value practice. The kids LOVED that they got to take off their shoes. (Okay, there was one who wasn’t so keen on it…and there were a lot of laces that needed to be tied before recess!)
Okay, that was fun! I handed my group of kindergartners and first graders tape measures (the non-metal kind) and told them they could measure whatever they wanted. What a hit! On so many levels. First, I showed them how they could measure how far they jumped. After being stuck inside all day due to rain, this was the perfect way to get them to move around a bit and still sneak in some great math. Once I showed them how…
