Our Geometric Work

The second graders have closely investigated geometry in the unit, Shapes, Blocks, and Symmetry. The unit developed the second graders ideas about 2-dimensional and 3-dimensional shapes and their characteristics and attributes.  They worked on different ways to sort, categorize, name and think about the relationships between them. They've worked closely with rectangles and rectangular prisms and also investigated symmetry.

They spent several days looking, sorting, thinking and drawing with geoblocks. They particularly enjoyed building small constructions with the geoblocks  and then taking it a step further to draw their 3-d design accurately. The children were encouraged to carefully identify the shapes of the faces on the individual blocks, as well as how the blocks come together. This was a challenging task, but the end result was great!

The geoboard is a popular math tool amongst the second graders, that allows them to explore geometric shapes and designs. These excited mathematicians built rectangles on the geoboard, paying close attention to the angles and length of each side and carefully created geometric designs on their geoboards. You can tell in the pictures how eager and proud they were of their masterpieces!

After much investigation of the rectangle and rectangular prism, the children worked with a partner to make boxes using rectangular pieces.  This activity allowed them to solidify the idea of how rectangles can be used to create rectangular prisms and further develop their sense of its structure. The children worked ever so carefully to build two boxes. They were given materials and first had to plan which pieces would fit together like a puzzle to make a box with a top, bottom and sides.  They each were enthusiastic and worked well with their buddy. Not surprisingly, they all pulled it off in no time!

Here's a glimpse into our geometric world.
