Teaching measurement and comparing lengths has many benefits. Young children that have a good understanding of measurement have the skills to compare attributes of objects and classify things in their environments in different ways. Measurement links math to their everyday lives, other school subjects, and increases understanding of number concepts and spatial skills.
At Kid’s Academy, measurement and comparing lengths are explained and taught clearly and concisely with video lessons and worksheet activities.

The video lessons include instruction on comparing lengths and height of objects. Students learn how to classify objects as tallest, shortest, or longer and shorter. Students use higher order thinking skills to answer questions such as: what is the second shortest object or what object is shorter than the giraffe but taller than the tiger? The recorded lessons about comparing lengths for kids include answering questions such as finding the correct illustration with clues such as: Emma is shorter that Jenny, Jenny is shorter than Sarah. The video teachers define measurement terms and show students how to think through the more difficult questions with illustrations and examples on the teacher whiteboard.

Often in life, measuring without a ruler or other tool is required. Students, using these video lessons have the opportunity to measure items using non-standard units as well as measuring using an inch ruler. Comparing non-standard units to standard measurement tools allows students to connect measurement to their world.

Think of activities that go beyond the video lessons. Comparing length for kids is more fun when learning is extended. Compare the heights of children in the home or classroom. In the classroom, who has the longest pencil as compared to the teacher’s pencil? Ask the students if it is better to measure the length of a book with paper clips or a broomstick. Go outside and measure the length of the playground with a yardstick and a ruler. Have fun with this math skill!

The video illustrations are colorful, engaging and relevant for school and home classes that are comparing lengths for 1st grade. Teachers and parents using these resources from Kids Academy find the videos ideal for teaching, re-teaching, practice and enrichment.

This physics video tutorial provides a basic introduction into conservative and nonconservative forces. Examples of conservative forces include the electric force, the elastic force, and the gravitational force. Examples of nonconservative forces include friction, the applied force, any push or pull action including the tension force. This video connects the work done by conservative and nonconservative forces with the conservation of mechanical energy and shows how it's related to the change in the kinetic energy and potential energy of an object.

What is culture? How do we define it and how does it change? We’ll explore different categories of culture, like low culture, high culture, and sub-cultures. We'll also revisit our founding theories to consider both a structural functionalist and a conflict theory perspective on what cultures mean for society.

In the 1920s, there was a blossoming of all kinds of art made by African Americans in the New York neighborhood Harlem. Let's call it a renaissance. While all the arts were having a great run, some extremely interesting things were happening in the theater. Writers like Langston Hughes and Zora Neale Hurston were writing plays, and black theater companies were drawing larger audiences than ever before.

This calculus video tutorial provides a basic introduction into the second derivative test. It explains how to use the second derivative test to identify the presence of a relative maximum or a relative minimum at a critical point. If the second derivative is positive at a critical number - a local minimum is present. If the second derivative is negative at a critical number - a local maximum is present. So to identify the relative extrema, find the first derivative, set it equal to zero and identify the critical numbers. Plug the critical numbers into the second derivative function to determine the concavity of the function to see if its concave up or concave down. If it's concave up - it's a relative maximum. If it's concave down, it's a relative minimum. You can confirm the results of the second derivative test using the first derivative test with a sign chart on a number line.

Hank veers away from human anatomy to teach us about the (mostly) single-celled organisms that make up two of the three taxonomic domains of life, and one of the four kingdoms: Archaea, Bacteria, and Protists. They are by far the most abundant organisms on Earth and are our oldest, oddest relatives.

In which John Green teaches you about the Little Ice Age. The Little Ice Age was a period of global cooling that occurred from the 13th to the 19th centuries. This cooling was likely caused by a number of factors, including unusual solar activity and volcanic eruptions. The Little Ice Age greatly impacted human social orders, especially during the 17th century. When the climate changed, and the weather became unpredictable, the world changed profoundly. Poor harvests led to hunger, which led to even less productivity, which even resulted in violent upheaval in a lot of places. All this from a little change in the temperature? Definitely.
