Pupil outcome: I can use knowledge of subtraction facts within 10 to subtract within 20 Key learning points: - Subtraction facts within ten can be applied to subtraction within 20, e.g. if 5 - 2 = 3 then 15 - 2 = 13 - A number line can...

Pupil outcome: I can use the special case when the product of two binomials is the difference of two squares. Key learning points: - The product of two binomials often produces three terms. - There are cases where the coefficient of the...

Pupil outcome: I can use knowledge of addition and subtraction facts within 10 to add and subtract within 20 Key learning points: - Addition facts within ten can be applied to addition within 20 - Subtraction facts within ten can be...

This video demonstrates how to calculate the work done by a spring force as a block falls and compresses a spring. It explains the principles of spring potential energy and its relation to work.

This video solves a physics problem demonstrating how to calculate the work done by gravitational force on an object moving along a curved path, and the resulting change in its potential energy.

Understand how to calculate the work done by variable forces like spring force using integration and Hooke’s Law. Learn the physics behind elastic potential energy and how force varies with displacement

Explore how potential energy diagrams reveal the interplay between force, position, and energy. Learn to interpret curves, apply F = -dU/dx, and calculate energy transformations using real physics problems.

Discover how mechanical energy—kinetic plus potential—remains conserved in systems under conservative forces. With real-world examples like roller coasters, this lesson simplifies a core law of classical mechanics.

Learn how to derive gravitational and elastic potential energy using the work-energy principle. Understand how conservative forces store and transform energy in physics systems like springs and gravity

In this video, we use substitution to take equations and rewrite them in the form of a quadratic so that we can solve them.

In this video, we find the difference quotient for two different functions.

This video discusses center-radius form of a circle. There are multiply ways to write the equation of the circle, but this is the most common form of it. In order to write this equation, you only need to know the center (h,k) and the...

In this video, we write a polynomial function when given the zeros of the polynomial.

In this video, we investigate how to find the determinants of 2x2 and 3x3 matrices.

This video discusses how to do the addition rule with Venn-Diagram type problems. To do this, you add the probabilities of each individual event and then subtract the intersection.

How do we add up the first "n" terms of a geometric sequence/series? In this video, we derive the equation to find the sum of a geometric series. Then, we use that rule to solve a few example problems where we add up the terms in a...

How do you add vectors, subtract vectors, and use a scalar on vectors? This video shows how to do all of these vector operations both algebraically and graphically. This video is for a precalculus class

Watch this video to find out the basics of writing an equation in point slope form!

This video practices solving systems of equations by substitution and elimination.
