Polygons

What makes a polygon? 

Have you read this book?  It's a terrific story about a triangle who changes into other polygons.

Here's a right triangle

Quadrangle (specifically a trapezoid)

Regular Hexagon

another hexagon (six-sided figure)

one more hexagon

a CONVEX polygon

a CONCAVE polygon



If the sides are CURVED it CANNOT be a polygon:

If the sides INTERSECT it CANNOT be a polygon:

(In addition, if the sides are OPEN it cannot be a polygon)

Year of the Panda

Have you read the book Year of the Panda by Miriam Schlein?
It's a terrific chapter book about a boy named Lu Yi who cares for an orphaned daxiong mao (giant panda).  Here's one book review about the story...

Quadrangles

Squares & rhombus...how are they alike/different?

Why is a square a special type of rectangle?

Can a kite be a parallelogram?



Compare/contrast trapezoids and rectangles

Sentences

In Language class we've been learning basic sentence structure. 
Nouns, verbs, subjects, predicates...
Here are some photos of us playing a subject/predicate game.
The little slips of paper have phrases (some have subjects; others have predicates).
Match two together and see if it makes a complete sentence.
We had a good time, and sometimes we made some silly sentences! :)

Geometry

What can you make with straws and twist-ties?

In math class, the possibilities are endless!

Triangle

Square

Trapezoid

rhombus

Here's a few pictures of our classroom. 

I'm looking forward to starting school with you.

Let's make it a great year together!
