Howcast - Lengthen the look of your legs with your attire and show off your bashful thick legs.

Howcast - Learn how to draw a pleat or fold on a fashion sketch from fashion designer Garo Sparo in this Howcast video.

Pupil outcome: I can mark points specified as a translation from the origin. Key learning points: - Use knowledge of polygon properties to identify a missing vertex. - Use known coordinates to plot a missing coordinate.

Pupil outcome: I can use the properties of a range of polygons to deduce the perimeters of compound shapes, including generalising a perimeter formula where appropriate. Key learning points: - You can identify how to find the perimeter...

Pupil outcome: I can draw citrus fruit juicers using the crating technique. Key learning points: - The crating technique can be used with isometric and perspective sketching. - When using the crating technique, it is important that the...

Pupil outcome: I can calculate the intercept point from a graph and from two coordinate pairs. Key learning points: - The y-intercept can be found by considering the graph. - The y-intercept occurs when the x value is zero. - The...

Pupil outcome: I can appreciate that writing linear equations in the form ay + bx + c = 0 may be more appropriate. Key learning points: - Linear equations can be written in multiple forms. - One of these forms is ay + bx + c = 0. - This...

This video walks you through the steps to creating a one-point perspective drawing of the interior of a room.

Miss Palomine talks about good writing techniques, such as how to hold the pencil properly, how to sit in the chair, and how to place the paper. After she explains the lined paper’s headline, midline, and baseline, she instructs the...

Once students undertstand how to identify the slope between two points they struggle to come to terms with. We will compare and contrast their characteristics with the algebraic definition of slope. By the end of this video, you...

In this video I will review how to draw and shade four basic forms: the cylinder, sphere,...

In this video we look at more examples of plotting straight lines onto graphs. This time the equations are a little trickier - such as having fractions for the gradients. When completing the table of values, if the equation has fractions...

Learn how to solve problems using linear programming. A linear programming problem involves finding the maximum or minimum value of an equation, called the objective functions, subject to a system of inequalities, called the constraints....

👉 Learn how to graph linear equations with one variable. When given a linear equation with one variable in the form x = a or y = c, the two forms of linear equations results in a vertical and horizontal lines respectively. The graph of...

👉 Learn how to determine whether two triangles are similar given the coordinate points of the vertices of the triangle. Two triangles are said to be equal when the corresponding angles of the triangles are congruent (equal) or when the...

In this video, we explore various optical illusions that demonstrate how our perception can be distorted. From lines appearing bent to circles appearing different in size, these illusions challenge our visual understanding. By...

👉 Learn how to define angle relationships. Knowledge of the relationships between angles can help in determining the value of a given angle. The various angle relationships include: vertical angles, adjacent angles, complementary angles,...

Learn about graphs. In this introductory video we will introduce coordinates, quadrants and the two axis: x-axis and y-axis.



The x-axis is the horizontal one, and the y-axis is the vertical one. You can remember...
