Spring SAVY 2015, Week 2 – Discovering the Third Dimension (Kindergarten)

Posted by on Tuesday, February 17, 2015 in SAVY blog.

It was another great week of SAVY! The students eagerly attacked the different challenges and problems that were presented. We continued exploring how different shaped could be decomposed and re-composed. We cut up square pieces of paper into triangles, rectangles and smaller squares. Then students used the smaller pieces of paper to compose pentagons, hexagons, and quadrilaterals. There was such rich discussion about this and how to count lines and vertices in the new shapes! Students also played games where they explored shapes through drawing or constructing with pattern blocks.

We also learned about angles and explored angles with straw protractors. We were particularly interested in right angles. As we explored our classroom, we found so many right angles! Students were also introduced to acute and obtuse angles. We will continue to explore angles as we classify shapes that have right angles.

One of our favorite activities was looking at a shape book, Which One Doesn’t Belong by Christopher Danielson. A free pdf can be accessed at http://talkingmathwithkids.com/2015/01/07/building-a-better-shapes-book/. On each page are four shapes, and we discussed which one did not belong on the page. The great thing about this book is that the author created it with the idea that a case could be made for any shape to be excluded. We had some great discussions about our reasons, and students enjoyed the challenge of coming up with different ideas. The author’s website, www.talkingmathwithkids.com, is worth exploring. It is a great resource for teachers and parents alike.
