Introduction to Angle Measure

Students are introduced to angles, learn their definitions, how to name them, and the idea of measuring angles. They also learn the number of degrees in a circle, a half-circle and a quarter circle.

Investigating Tessellations Filling 2-D Space

Students explore tessellating, the arrangement of shapes that can fill a plane with no overlaps or gaps.

Lines, Angles, and Figures

This video from WOUB Athens and WVIZ Cleveland takes you step by step through a review of the math concepts of lines, angles, and figures.

Measuring Area

Students calculate the areas of polygonal figures. They use hash marks to create square units and to count the units, including half-units.

Measuring Different Lanes on the Track

In this video segment from Cyberchase, Bianca competes in her first track meet, but doubts the fairness of starting further back in the inside track lane for a 200 meter race.

Perimeter and Area Together

Students recognize that rectangles can have the same perimeters but different areas. They are asked to calculate the perimeters and areas of different rectangles and understand the concept of maximum area.

Plotting Pairs of Coordinate Points in All Four Quadrants to Construct Lines

Students learn about and practice graphing, plotting points, drawing line segments, and finding the coordinates of points of intersection.

Points of Origin

This KET animation illustrates positive and negative measurement on a straight line and on a flat plane using a point of origin.

Predicting the Angle of a Bouncing Ball

In this Cyberchase video segment, the CyberSquad is trapped in an icy cave. In order to escape, they must use the principles of a bouncing ball to transport a key from one side of the icy cave to the other.

Properties of Circles

Students practice circle geometry by learning to draw a perfect circle using a radius and finding the center of a circle by folding it into quarters.

Relating to Metric Measurement

Students become more familiar and proficient at metric unit measurement by examining measurement and predictions concerning indoor tracks (200 m) and outdoor tracks (400 m).

Skate-Off: Final Round, Inez vs. Rimm
