Hierarchy

Polygon Attributes

We have been identifying attributes of polygons and using that information to sort them.

Polygon Attributes

Triangles

Triangles can be sorted into categories.  Watch the Study Jams video to explore the different types of triangles and their attributes.  Be sure to test yourself at the end.

Polygons

We have begun identifying and sorting polygons into categories.  I hope are having fun because math is fun! Click on the link below to learn more about polygons.  Scroll down to the middle of the page and look for "Play With Them!" to play with interactive polygons.  You can create all the different types of polygons we have been learning about.

Rounding decimals to nearest whole number using number line

In the past week, we have been working with decimals.  We have learned to understand decimals using base ten pieces, base ten grids, place value charts and number lines.  We have learned to read and write decimals in standard form, and expanded form.  Watch this video to learn how to round decimals to the nearest whole number using a number line.
