Procyon is the seventh brightest star in the sky

Procyon is a binary star system, composed of a white main sequence star and a white dwarf star.

1.6A Audience: First Grade. Behavior: Classify 2-dimensional shapes using informal geometric language. Condition: Ancho Chart. I would introduce some familiar 2D shapes and ask the students to identify how many sides and vertices using an anchor chart.

Photo made at a very elegant facade of a building in Portobuffolè in the province of Treviso in the Veneto (Italy). In the image you see three windows with closed wooden shutters. they form the vertices of a triangle with the base at the top and center of which is a painted coat of arms. Under the pitch of the roof and in the shade band you see two ovals lying.

Triangle Measurement Interactive Notebook Page - showing proof that the interior angles of a triangle have a sum of 180 degrees. So much better than just telling students. Show the proof.

Triangle Measurement Interactive Notebook Page. Rip off the angles and put all the vertices together to show why they add to equal 180 degrees!
