Calder Mobiles with a Math twist

student work
teacher example
I was cruzing on pinterest a few weeks ago and spotted this pin where straws were being used to create a 3D shape.  Fourth grade teachers in the past have mentioned to me that students need to understand shapes better for the state test.  I have done many different projects where I have had students create a 2D piece of work that is then folded to create a 3D pyramid or cube.  This shape using straws and string struck me as intriguing and I immediately knew I was ready to try this out with a  group of students.  I decided to try my idea with 3rd grade and since I already had the needed materials in my classroom began immediately with the idea of creating a 3 sided pyramid.  The materials were simplistic:  plastic straws, string, plastic needles, paper clips, scissors and a ruler.  The first week was dedicated to having student measure and cut the straws into 2" pieces.  This turned out to be a full lesson in itself as they need reinforcement on how to use the ruler to measure.  We wasted a few straws but success with measurements far outweighed the cost of the straws. (I was able to obtain some donated straws as the weeks went buy so that was off set anyway.)  The needles were used to allow for ease of putting the straws onto the strings.  Next step was knot tying.  With Velcro shoes, kids aren't very good at this anymore and I knew I did not want to be taxed with tying all the knots.  I challenged the students to create the pyramid, a cube and a rectangular cube.  After a visit with the 3rd grade Math teachers, I knew what vocabulary I needed to concentrate on to make connections to their classroom work.  I encouraged making a minimum of four shapes.  They view the works of Alexander Calder and his work with both mobiles and stables.   The final step was to actually create their own mobiles with

 attention to balancing on a fulcrum.  All the vocabulary they had been exposed to in 2nd grade Science was review during this process.  I must say, much of this project was a very painful experience.  Often, I doubted whether the students would actually achieve my goal and complete a Calder mobile.  Witnessing the pride of accomplishment when completed was so worth it!
Oh, and this is my 300th post!!! I never knew I had that much to say.

Symmetry and Monarch Butterflies

With the Fiesta dance just a few days away, first graders needed to create a decoration that also incorporated some of the elements and principals of art.  Symmetry seemed to be a good focus along with color and color mixing to create these dynamic Monarch butterflies.  Students began the lesson by review knowledge achieved in Science class when they learned about the life cycle of the Monarch and it's migration habits with winters in Mexico.  The monarch seemed to be a good focus for a Fiesta decoration in that these butterflies spent a good portion of their life in Mexico as well as most parts of the U.S.  Students used red and yellow paint to make a symmetrical print. Week two, sharpie markers were used to add detail and eyes.  Pipe cleaners became the antenna for the butterflies.  These will also double as eye catching decorations for the upcoming dance.

Shape Dinosaurs in habitats

This is a follow-up to a post a few weeks ago I was leaving for a sub.  Here is the previous post.  I had wanted Kindergarten students to practice cutting skills and then form a dinosaur of their choice out of the shapes.  I didn't think they would have time to complete everything in one session and I was correct.  The substitute worked with student on cutting out their shapes and that is all they accomplished.   The next week I talked with students about habitats and specifically, what the habitat for a dinosaur might look like.  The discussions included foods and other things that might be necessary for survival.  Students set to work drawing a habitat and adding color.  Once these were completed, I handed out their envelopes of shapes from the previous class and had them play with them to form a dinosaur of their choice.  It could resemble a dinosaur they knew about or it could be a fantasy dino.  I had them play for awhile and then allowed them to glue the dinosaur onto the habitat.  The project was a hit and students were excited to take them home.  I wanted to save them for the hall bulletin board because they really are "just that cute"!  So here are a few photos.
Two Dinosaurs because the student wanted one to fly

This one looks like a prehistoric porcupine.

This student wanted to make sure her Dino had water

Another pair of dinosaurs

Lots of scales or lots of legs...not sure

Lots of detail added to this one using crayon after the glue down.
