Pupil outcome: I can recognise the effect of applying the transformation y = af(x) to a graph. Key learning points: - Desmos is an effective tool for showing the effects of this transformation - The actual function itself does not need...

Pupil outcome: I can appreciate that the trigonometric functions are derived from measurements within a unit circle. Key learning points: - The unit circle is a circle with a radius of one. - The unit circle is centered on the origin. -...

Pupil outcome: I can use my knowledge of similarity and Pythagoras' theorem to solve problems. Key learning points: - Right-angled triangles can be seen in real-life (e.g. ladder against a vertical wall). - A ratio table can help you...

Pupil outcome: I can recognise that similar shapes have sides in proportion to each other but angle sizes are preserved. Key learning points: - Two shapes are not similar if there is a pair of lengths with a different multiplicative...

Pupil outcome: I can investigate transformations using dynamic software Key learning points: - Dynamic software is a tool that can be used to explore transformations. - There are many benefits to using this tool. - Different...

In this video, we investigate how changing the linear dimensions of a three dimensional solid affects the volume and surface area. Specifically, how do we solve for missing values (like side length, volume and surface area) when we are...

In this video, we investigate how changing the linear dimensions of a 3d solid will affect the volume and surface area. After a dilation of a certain scale factor, how can that scale factor be used to predict the new volume or surface...

In this video, we practice calculating how volume and surface area would change as we change the linear dimensions of 3d figures.

In this video, we will dilate figures on the coordinate plane when the center of dilation is not the origin. The first example is a standard dilation (enlargement) with a non-origin center, and the second example gives you both the...

In this video, we learn how to dilate figures from the origin. We do one example that is an ENLARGEMENT (has a scale factor greater than 1), and another example that is a REDUCTION (scale factor that is between 0 and 1).

Though the world's first model aircraft, a Spitfire, was built in a scale of 1:75, the resulting model would fit into the full-size equivalent more than 370,000 times over. Discover how scale is calculated in three dimensions. Maths -...

In this video, we will cover the remaining commands in AutoCAD 2D that are used for creating and modifying more advanced shapes and objects. You will learn how to use commands such as scale, offset, fillet, chamfer, and array, which are...

This video explains how to understand the four transformations in maths: translation, rotation, reflection, and enlargement. Two sets of practice questions are provided at the end of the video: performing and describing transformations.

This video explains what similar shapes are and how to use scale factors to find the missing length of one of the sides.

In this video, the teacher explains the four types of transformations in math - translation, reflection, rotation, and dilation. They then use a given problem to demonstrate how to identify a transformation that would result in a similar...

In this lesson, students will learn how to draw images of dilation with a negative scale factor using the center of dilation at the origin on the coordinate plane. They will understand that a dilation takes a segment not going through...

👉 Learn about dilations. Dilation is the transformation of a shape by a scale factor to produce an image that is similar to the original shape but is different in size from the original shape. A dilation that creates a larger image is...

In this video, students learn how to find the coordinates of points along a straight line using similar triangles. They are taught to set up ratios with the vertical side (rise) first and the horizontal side (run) second.

👉 Learn about dilations. Dilation is the transformation of a shape by a scale factor to produce an image that is similar to the original shape but is different in size from the original shape. A dilation that creates a larger image is...

This video is a comprehensive lesson on circle theorems, including an extension on the topic. The presenter covers the key four circle theorems that students should know, including the arrow shape, bow shape, quadrilateral, and...

In this lesson, students will learn how architects create scale drawings using fractions and decimals. They will understand the concept of a scale factor and how it is used to enlarge or reduce dimensions.

👉 Learn about dilations. Dilation is the transformation of a shape by a scale factor to produce an image that is similar to the original shape but is different in size from the original shape. A dilation that creates a larger image is...

The video provides a clear explanation of the sine, cosine, and tangent functions and their corresponding graphs. It starts by introducing the unit circle and how it relates to the functions. Then, it explains the formulas for each of...
