From multiplying and dividing to identifying polygons to telling time to naming parts of a whole, this collection can serve as a baseline for third grade math instruction. Each resource in the collection is designed to meet one or more of all 37 Common Core State Standards in third grade mathematics.
Module 6: Connecting Algebra and Geometry
9th - 12th CCSS: Designed
A geometry module connects algebraic reasoning to geometry. It challenges scholars to investigate the slope criteria for parallel and perpendicular lines, prove theorems involving coordinate geometry, and write equations for circles and...
Polygons in the Coordinate Plane
8 mins 6th - 10th CCSS: Adaptable
You'll be ready to plot something after a lesson on coordinate geometry! The video instructor begins by discussing how to plot four points to create a quadrilateral. The second example demonstrates finding the area and perimeter from the...
Area and Perimeter of Triangles: Lesson
3 mins 6th - 10th CCSS: Adaptable
Go from a parallelogram to a triangle. A segment of an extensive playlist on basic geometry shows the derivation of the formula for the area of a triangle. The resource works examples that require finding a missing side or height to...
Area and Perimeter of Rhombuses and Kites: Lesson
4 mins 6th - 10th CCSS: Adaptable
Flip the triangles up and create a parallelogram. Using the idea of transformations, the video develops the area formula for rhombi and kites. The segment of an extensive geometry playlist uses the formula to find the areas of different...
Area and Perimeter of Trapezoids: Lesson
4 mins 6th - 11th CCSS: Adaptable
With a little averaging, a trapezoid becomes a parallelogram. The section of an extensive geometry playlist shows how to derive the formula for the area of a trapezoid by changing it into a parallelogram. Using the formula, the video...
Area and Perimeter of Rectangles: Lesson
3 mins 4th - 9th CCSS: Adaptable
Around and in—take a different look at rectangles. A portion of a basic geometry playlist discusses the area and perimeters of rectangles. Using the formulas, the presentation works perimeter and area examples with rectangles and squares.
Go with Green Triangles—Linking Length, Perimeter, Area, and Volume
6th - 8th CCSS: Designed
Investigate and compare scale factors of perimeter and area. Young scholars use an applet to manipulate the sides of similar rectangles. They then make perimeter and area calculations and compare the ratios to finish the second in a...
