This video shows how to find the equation for the axis of symmetry for a parabola, given the equation of the parabola in standard form or vertex form. Students are shown the equivalence of vertex and standard forms, and how to find the coordinates of the vertex.

Why are there 12 hours in a clock rather than 10? In this video we explain why 12 is the preferred number for clocks and calendars. 

In this video tutorial, students are shown how to use their counting skills to add two numbers. Three worked-out examples provide an opportunity for students to see how to use their counting skills to add.

In this video tutorial, students are shown how to use their counting skills to subtract two numbers. Three detailed examples show how to use counting to subtract.

In this video tutorial, students are shown how to use the technique of Counting On to improve the speed and accuracy of their counting, using three different examples. The video develops the concept of counting and cardinality.

In this video tutorial, students are shown how to use Skip Counting and Counting On to quickly and accurately count large numbers of items. This video lays the groundwork for developing addition skills.

In this video tutorial, students are shown how to count to 20 using three different examples. The video develops the concept of counting and cardinality.

Learn the basics of decreasing functions. Graphical and algebraic representations of decreasing functions are shown, as well as examples of such functions.
