The first grade mathematicians are exploring 3-D shapes.  The Kindergarten mathematicians shared their shape riddles posters.

The first graders have been observing, describing, and comparing 3-D shapes.

They are developing vocabulary to describe the characteristics of 3-D shapes, and name them.  The children are enjoying learning the names triangular prism, rectangular prism, hexagonal prism, and octagonal prism.  They are also beginning to explore pyramids.  The children totally immersed themselves in the exploration of drawing 3-D shapes such as cubes and rectangular prisms.  We read a math adventure book entitled Sir Cumference and the Sword in the Cone.  The book introduced the mathematical "two's test" also known as Euler's Law. The children practiced counting points (vertices), edges, and faces of solids to get ready to test Euler's Law in the coming week.

The kindergarten math students had lots of fun sharing their shape riddles with the first grade students.  The first graders listened with interest and respect.  It was awesome!

It's wonderful to see children bring into free choice time what they learn during lessons.  One first grader made a book about shapes and shared it during math class.  Another child made a sign of 3-D shape drawings, and a third child spent most of her free choice time exploring drawing 3-D shapes.

Here are a few photos of the kindergarten mathematicians sharing their shape riddles.  They are truly experts on sharing - such confidence, poise, and enthusiasm!!!

I'll be adding more posts next week.
Have a peaceful week,
