There was a tendency to make big, strong and heavy shields that could protect a soldier’s entire body. It also had to be able to be moved around the battlefield. The only solution was to put wheels on them. These were to be known as mobile shields.
Their purpose was to provide cover to one or several soldiers that were advancing across the field or no-man's land. The idea of shields on wheels was actually born a few decades earlier, during the Cuban War, when US troops used the first movable shields.

The idea was adopted by the British and French armies and brought into service during WW1. Even though all designs included heavy steel plates that were capable of withstanding small arms fire, their use was questionable in reality.

Our Mission: MashUp Math is our creative solution to reviving students' passion and interest for learning mathematics. As young educators, we know that all students learn math differently and that a one-size-fits-all approach is simply ineffective. The idea that the ability to understand mathematics is reserved for a select few did not sit well with us.

In addition to sharing free teacher resources (which are teacher created resources) in the form of teacher worksheets, we share new YouTube math videos every week that help math teachers and students to better understand mathematics and the common core. Our lessons can be aligned with the common core standards for common core math and are immensely popular with flipped learning educators and anyone experimenting with flipped classroom learning.

As educators, we know what it takes to be a super math teacher and that we can’t always do it alone. In addition to our cool math videos, we share articles, blogs, inspirational quotes, teacher math worksheets, and math worksheets. Whether you teach in the flipped classroom, operate in blended education or online blended learning, or are interested in finding cool math online, MashUp Math will have something for you!

Many students think of us as a math tutor online or as their on-demand online tutor. Others trust us for all things related to online math education—coming to use when they find themselves thinking “I don’t understand my homework assignment! and need some homework help!

It is also a part of our mission to make progressive steps in mathematics education. For one, our content is created with the goal of moving students from a fixed mindset to a growth mindset. We also aim to meet the unique needs of ESL math students and support math for girls as well.

Many of our users serve as a special education teacher and use our cool videos to support their special education students with special needs. Our free online math lessons are also high adaptable to your homeschool curriculum and should be added to your list of free homeschool resources.

We are also very involved in the edtech world and are very popular with Google Classroom educators, Math Games Classroom Educators, and teachers who support the use of iPad for education!

So if you could use some help with everyday math and are a student with a unique learning style or learning styles—like Visual Auditory Learning! Or if you’re tired of math games and are more interested in an easy-to-follow tutorial, check us out and learn math with us. No matter your school’s standards of learning, our YouTube Math Videos Lessons will work for you!

This tutorial demonstrates how to solve some single variable expressions which can be solved via addition and subtraction methods.

Geometry on Khan Academy: We are surrounded by space. And that space contains lots of things. And these things have shapes. In geometry we are concerned with the nature of these shapes, how we define them, and what they teach us about the world at large--from math to architecture to biology to astronomy (and everything in between). Learning geometry is about more than just taking your medicine ("It's good for you!"), it's at the core of everything that exists--including you. Having said all that, some of the specific topics we'll cover include angles, intersecting lines, right triangles, perimeter, area, volume, circles, triangles, quadrilaterals, analytic geometry, and geometric constructions. Wow. That's a lot. To summarize: it's difficult to imagine any area of math that is more widely used than geometry.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

For free. For everyone. Forever. #YouCanLearnAnything

This is a math video lesson to help you with new math, math tricks, and or simple math questions you may have.

Animal adaptations for kids is a video that explores the different ways that animals can adapt to their environments. There is a number of ways that different animals do this, from Migration or Hibernation, to Body Structures and even changing their colors and in this video we will explore them all. There are different kind of animal adaptions Behavioral Adaptions, Physical Adaptions, and Life Cycle Adaptions each animal might use a different technique but ultimately they are adapting to survive in their environment.

After viewing this video we invite you to download and go through our free Animal Adaptations lesson plan with more activities, learning content, worksheets and more! When completed your students will be able to identify and describe various
animal adaptations used for survival in the environment.
