Episodes:

• Math Shorts: Additive Inverse

  This animated Math Shorts video from the Utah Education Network explains the term additive inverse and provides several examples that demonstrate the concept. In the accompanying classroom activity, students create equations and solve problems that involve adding groups of negative and positive integers that sum to zero. To get the most out of this activity, students should be familiar with plotting positive and negative integers on a number line.

• Math Shorts: Reflection

  In this animated Math Shorts video from the Utah Education Network, learn about reflection, one type of movement for geometric shapes. The animation relates the geometric meaning of reflection to its more common understanding—a mirror image—and then displays geometric shapes on a coordinate plane reflecting through the x-axis and y-axis. In the accompanying classroom activity, students design a geometric figure in one quadrant and then reflect it into at least one other quadrant. They earn points by designing more complicated shapes or reflecting a shape into more quadrants.

• Math Shorts: Rotation

  In this animated Math Shorts video from the Utah Education Network, learn about rotation, which describes how a geometric shape turns around a point, called the center of rotation. When a geometric shape rotates on a coordinate plane, it stays exactly the same distance from the center of rotation. In the accompanying classroom activity, students are given two rotations from a handout and work in pairs to try to determine whether one figure is a rotation of the other figure around the given point. If the figure is a rotation, the student pair must add one more rotation to the grid. If the figure is not a rotation, the student pair must add one accurate rotation to the grid.

• Math Shorts: Scientific Notation

  This animated Math Shorts video explains the term scientific notation and provides several examples in converting extreme numbers to and from scientific notation. It also demonstrates how to multiply numbers using scientific notation. In the accompanying classroom activity, students practice writing numbers in scientific notation and develop real-world problems for each other to solve.

• Math Shorts: Slicing 3D Figures

  This animated Math Shorts video helps students understand the two-dimensional figures that result from slicing solid three-dimensional figures. The video demonstrates this using cylinders and right rectangular pyramids as the three-dimensional figures. In the accompanying classroom activity, students create and slice play dough figures and then describe the resulting shapes.

• Math Shorts: Translation

  In this animated Math Shorts video from the Utah Education Network, learn about translation, which occurs when a geometric shape slides from one location to another on a coordinate plane. The shape itself doesn’t change, just its location. The animation also explains mapping notations, which designate how far and in what direction a shape moves. In the accompanying classroom activity, students solve a series of practice translation problems and explain to one another what they did to solve them.
