Translations

Not only did we learn the Translation Hustle Dance . . Do the Hustle, but we manipulated figures before we glued them to our journal.

 

Symmetry

This week we are continuing our geometry unit with testing lines of symmetry and connecting that with our knowledge of transformations (reflections specifically) and congruency.  We also introduced a new math tool.  I just call it the Red Mirror.  It helps us see the reflected figure and to test lines of symmetry.  Really cool!

Look, We are using our journals!

We often refer to our journals when in need.  We are defining 2D and 3D figures based only on attributes.

3D Figures

Our journal entry for 3D figure vocabulary.

More Polygon Attributes

Today we added to our journal.  In fourth grade, we will define and identify 2D figures by their attributes.  We created two journal pages to help us organize the attributes.

Measurement

OK, sorry this has taken so long.  Here it is, all my Measurement materials in one big post.  This will include our class foldables as well as anchor charts.  Sorry if anything is repeated.

Combinations

Points, Lines, and Angles

We started our Geometry unit today by creating our Point, Lines, and Angles foldable.  They will use this throughout the unit.  I explained to the students today, we will not measure angles in fourth grade.  But, we will have to identify angles within a 2D figure.  As well as identify parallel and perpendicular lines within 2D figures.

Converting Measurement

We are learning about Units of Length this week.  We are also learning how to convert customary units of length.  We learned a song to help us.
