Applications of Properties of Quadrilaterals in the Coordinate Plane
Students explore the concept of quadrilaterals. In this quadrilaterals lesson, students use the slope formula, midpoint formula, and distance formula to justify that a given quadrilateral is a parallelogram.
Curated OER
Translations
Students perform translations on different polygons. In this geometry lesson, students create figures that will be used as an assessment to represent transformation. They perform hands on creation and relate it to the real world.
Curated OER
Discovering Pi
Students investigate the math concept of Pi (specifically, what pi is, the significance and how it is used in the real world). This is a hands on lesson in which the students actively participate with their investigations.

Square Numbers Closure Activity
Students discuss square numbers. In this math lesson, students find square numbers and support their answers. Students find sums and products that are square numbers.
Curated OER
Investigating the Idea of Cos
Fifth graders use cos to solve problems involving right-angled triangles. They solve equations of the form cos(++) = a, for a between -180 and 360 degrees. They state the value of cos(++) in special cases and graph y = cos(++).
Curated OER
Bisecting Angles and Segments
Learners bisect angles and segments using a mira. They measure the original angles and segments and the angles and segments formed by bisecting to better see the relationship between them.
Curated OER
Foil Fun
Second graders be having hands-on experiences with three-dimensional solid shapes. They investigate the features of solid shapes and examine the names for them. They are introduced to making nets for 3D shapes.
Curated OER
A Game of Chance
Students explore probability through cooperative group activities and interactive video technique.
