# Q3W5 Honors 6th Grade Math

Teacher Kimberlie Hymes Honors Math 6th 23 Geometry
Standard(s) Taught

6.G.1.1

Find area of right triangles, other triangles, special quadrilaterals, and polygons by composing into rectangles or decomposing into triangles and other shapes; apply these techniques in the context of solving real-world and mathematical problems.

6.G.1.3

Draw polygons in the coordinate plane given coordinates for the vertices; use coordinates to find the length of a side joining points with the same first coordinate or the same second coordinate. Apply these techniques in the context of solving real-world and mathematical problems.

Learning Targets and Learning Criteria

• use absolute value to determine distance between integers on the coordinate plane to find side lengths of polygons.
• draw polygons in the coordinate plane and find the area enclosed by a polygon by composing or decomposing using polygons with known area formulas.
• find the perimeter of irregular figures using coordinates to find the length of a side joining points with the same first coordinate or the same second coordinate.
• determine distance, perimeter, and area in real-world contexts.

• show the area formula for a parallelogram by composing it into rectangles.
• justify the area formula for a right triangle by viewing the right triangle as part of a rectangle composed of two right triangles.
• show the area formula for a triangular region by decomposing a triangle into right triangles. For a given triangle, the height of the triangle is the length of the altitude. The length of the base is either called the length base or, more commonly, the base.
• understand that the height of the triangle is the perpendicular segment from a vertex of a triangle to the line containing the opposite side. The opposite side is called the base.
• understand that any side of a triangle can be considered a base and that the choice of base determines the height.
• deconstruct triangles to justify that the area of a triangle is exactly one half the area of a parallelogram.
• find the area for a trapezoid by decomposing the region into two triangles. I can decompose rectangles to determine the area of other quadrilaterals.
• determine the area of composite figures in real-life contextual situations using composition and decomposition of polygons.
• determine the area of a missing region using composition and decomposition of polygons.

Classroom Activities

This week we started out Geometry Unit. We will be diving right in and learning about area and volume this week.

Assignments Due

“Geometry Homework” Due 2/8/17 (Mathspace)

We will be taking our DIA 3 next week Thursday, 2-15-18

This covers all of Expressions and Equations as well as Geometry standards.

If additional help is needed, students are encouraged to view a lesson regarding a given topic on Khan Academy. This website is free and provides both video instruction as well as practice problems.

Students are able to complete additional practice on both MathSpace and IXL.
