In this video, the teacher explains how to write complex algebraic expressions for real-world scenarios using variables and operations. The teacher emphasizes the importance of defining the variable before writing the expression and...

Using digitalRead() to read binary inputs with Arduino.

In this video, the teacher explains how to use the area model to multiply multi-digit numbers. They review the concept of a product, the relationship between multiplication and repeated addition, and the representation of multiplication...

This video covers Three Dimensional Vectors. This video goes over the various properties associated with three dimensional vectors. 3 basic examples are also covered illustrating how to solve problems that make use of vectors in space.

👉 Learn all about binomial expansion. A binomial expression is an algebraic expression with two terms. When a binomial expression is raised to a positive integer exponent, we usually use the binomial expansion technique to easily expand...

👉 Learn how to evaluate trigonometric functions using trigonometric identities. Trigonometric identities are equalities that involve trigonometric functions. We will focus on the cofunction identities and even-odd identities. The...

👉 Learn how to evaluate the tangent of a half-angle. When given the value of the tangent of an angle, we can evaluate the tangent of half the angle using the tangent half-angle formula. When the value of any other trigonometric function...

In this week’s episode we follow a construction site drone, examine tunable window technology, learn how words are represented in the brain and finally we examine 240-million-year-old fossils.

Make a line plot to represent fractional length measurement data (halves and quarters).

In this video, students learn how to model numbers using base 10 blocks. They explore different representations of numbers, such as 4 hundreds and 13 ones being equivalent to 41 tens and 3 ones.

In this video, students learn how to use equivalent fractions to subtract fractions and mixed numbers with unlike denominators. The teacher explains the process step by step, emphasizing the importance of finding a common denominator and...

The video is an educational lecture on line charts and their use in visualizing time series data. The presenter explains how line charts are primarily used to display data with time as one of the variables, and demonstrates how to read...
