New ReviewFactoring a polynomial by grouping gets easier and easier with the more practice you get. In this video I will cover a very helpful tip you can use to avoid making mistakes

It's a math teacher's dream!

A satellite in elliptical orbit speeds up as it approaches the planet—thanks to angular momentum conservation. Learn how to calculate angular speed at perihelion using Kepler’s laws and orbital geometry.

A video entitled "Volume of Composite Shapes" which shows how the volume formulas vary based on the shape of the base.

A video entitled "Volume of Spheres" that covers how to calculate the volume of a 3D sphere.

Learn how to calculate the gravitational force between a hollowed-out sphere and a point mass using mass subtraction and superposition—an essential technique for solving complex gravitation problems in AP and IB Physics.

Explore what happens if you fall straight through Earth—using Newton’s Shell Theorem, simple harmonic motion, and real gravitational data. Understand why every straight tunnel gives the same 42-minute trip, and how gravity behaves inside...

Pupil outcome: You can find one more or one less using representations. Key learning points: - Secure understanding of one more/one less using a variety of manipulatives . - Use the stem sentence one more than... one less than... -...

Pupil outcome: I can recognise, name and compare three different 3D shapes. Key learning points: - Recognise similar shaped objects and be able to explain how they are similar. - A cuboid is shaped like a box. - A cube is a special...

Pupil outcome: I can explain how numbers that are made out of pairs of 2 are even numbers and numbers that cannot be made out of pairs are odd numbers. Key learning points: - We can group representations of numbers according to whether...

Pupil outcome: I can use representations to show that the number before a given number is one less and the number after a given number is one more. Key learning points: - The number before a given number is one less than it. - The number...

Pupil outcome: I can explore, discuss and compare the different arrangements that can be made with cubes. Key learning points: - Know that cubes can be arranged in different ways. - Recognise when arrangements are the same, even when...

Pupil outcome: I can recognise that the number before a given number is one less and the number after a given number is one more. Key learning points: - Movement is magnitude. As you move forwards through the counting sequence the...

Pupil outcome: I can use mathematical vocabulary such as left, right, above, below and between to describe position. Key learning points: - Left and right can be used to describe position. - Position can be described using other...

Pupil outcome: I can explain the concept of squared and cubed numbers and calculate them. Key learning points: - A square number can be represented by dots making a square. - A square number is the product of two identical integers. - A...

Pupil outcome: I can state the factors and multiples for different numbers and identify square and cube numbers. Key learning points: - Multiples of a given number are the product of that number and an integer. - Factors of an integer...

Pupil outcome: I can calculate the scale factor used to enlarge a volume and use it to find missing lengths. Key learning points: - You can calculate the scale factor from the two volumes. - Having calculated the scale factor, you can...

Pupil outcome: I can recognise and name cones, cylinders, cubes, cuboids and spheres and describe their properties. Key learning points: - A property of a 3D shape can be the number of faces, edges or vertices it has. - Each face of a 3D...

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 solve two equations with rational exponents (fraction exponents). In order to solve equations with rational (fraction) exponents, you first isolate the value that is raised to the rational exponent. Then, you raise both...
