Half a circle sleeping line
Half a circles sleeping line
Half a circle sleeping line
to make the number two

Half a circle, half a circle
Half a circle,half a circle
Half a circle,half a circle
to make the number 3

Standing ,sleeping,standing line

Standing,sleeping,standing line
to make the number 4

Sleeping,standing,half a circle
Sleeping,standing,half a circle
Sleeping,standing,half a circle
to make the number 5

C curve and circle in
C curve and circle in
C curve and circle in
to make the number 6

Sleeping line and slanting line
Sleeping line and slanting line
sleeping line and slanting line
to make the no.7

C curve it goes up
C curve it goes up
C curve it goes up
to make the number 8

Small a circle, standing line

small a circle, standing line
to make the number 9

What do you know about the country of Mexico? Did you know its official name is the United Mexican States? In All about Mexico for Kids, you and your students will learn a lot about the country's rich history. In fact, lots of really cool remnants of the past, such as ancient cities and pyramids. Lots of them are part of modern cities and towns.

Mexico's terrain is pretty diverse, from high mountains and plateaus to low coastal plains and deserts. Some parts are tropical, so the climate ranges from temperatures typical of deserts to those common to rainforests. The country borders Guatemala and Belize in the southeast and the states of California, Arizona, New Mexico, and Texas in the north. It also touches the Pacific Ocean, the Gulf of Mexico, and the Caribbean Sea.

There are lots of different kinds of animals that live in this country. Mexico actually boasts the most reptiles than any other place in the world. If you visit Mexico, you might find jaguars, pumas, iguanas, lizards, monkeys, or parrots. Of course, it would depend where you are in the country since the habitats are diverse. In the nearby sea or ocean, you might see whales, manta rays, or manatees!

The history of this beautiful country is usually divided into three general periods: early, middle, and recent. The Early period included several ancient societies and civilizations, such as the Olmecs, Mayans, and Aztecs. The Olmecs were the first known society, which existed starting in 1200 BC. The Middle period lasted from around 1519 to 1810. In 1810, which marks the start of Mexico's recent history, a rebel leader and others collaborated to gain Mexico's independence.

We hope you and your student(s) enjoyed learning about this fun country and its history! If you want even more information, head over to our website and download one of our many free lesson plans, full of activities, worksheets, and more!

In which John Green, Hank Green, and Emily Graslie teach you about the Anthropocene, an unofficial geological era that covers the last century or so, in which humanity has made massive progress. We've discovered the Higgs-Boson particle, and awesome electric cars, and amazing smartphones. So all this collective learning and progress has been good for everyone, right? Maybe not. We'll look at some of the pros and cons of all this "progress," including environmental impact, changes in the way people live and work, and political changes and wars that come along with the modern world. We've come a long way, but there's a long way to go. Crash Course will also take a look at what's going to happen in the near future. If we manage to make our way through the coming bottlenecks, we could be OK in coming centuries. Don't get too hopeful, though. The Sun will eventually die, and the Earth will be destroyed, and later the universe will eventually experience heat death. But we won't talk about those downers until next week.

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.

Precalculus on Khan Academy: You may think that precalculus is simply the course you take before calculus. You would be right, of course, but that definition doesn't mean anything unless you have some knowledge of what calculus is. Let's keep it simple, shall we? Calculus is a conceptual framework which provides systematic techniques for solving problems. These problems are appropriately applicable to analytic geometry and algebra. Therefore....precalculus gives you the background for the mathematical concepts, problems, issues and techniques that appear in calculus, including trigonometry, functions, complex numbers, vectors, matrices, and others. There you have it ladies and gentlemen....an introduction to precalculus!

Linear Algebra on Khan Academy: Have you ever wondered what the difference is between speed and velocity? Ever try to visualize in four dimensions or six or seven? Linear algebra describes things in two dimensions, but many of the concepts can be extended into three, four or more. Linear algebra implies two dimensional reasoning, however, the concepts covered in linear algebra provide the basis for multi-dimensional representations of mathematical reasoning. Matrices, vectors, vector spaces, transformations, eigenvectors/values all help us to visualize and understand multi dimensional concepts. This is an advanced course normally taken by science or engineering majors after taking at least two semesters of calculus (although calculus really isn't a prereq) so don't confuse this with regular high school algebra.

Trigonometry on Khan Academy: Big, fancy word, right? Don't be fooled. Looking at the prefix, tri-, you could probably assume that trigonometry ("trig" as it's sometimes called) has something to do with triangles. You would be right! Trig is the study of the properties of triangles. Why is it important? It's used in measuring precise distances, particularly in industries like satellite systems and sciences like astronomy. It's not only space, however. Trig is present in architecture and music, too. Now you may wonder...how is knowing the measurement and properties of triangles relevant to music?? THAT is a great question. Maybe you'll learn the answer from us in these tutorials!

DeepSeek-R1 is a strong performing, open source reasoning model with several distilled versions that can be run locally. Here, we walk through the DeepSeek-R1 paper to review the details of the training methodology, download the 14b distilled model via Ollama, test generation / JSON-mode, and then test it in a fully local "deep research" assistant that performs web-research / summarization w/ an iterative reflection step to improve its results.

Why are timed math drills bad for kids? And how do timed math drills promote math anxiety?

Let's explore the research of Stanford Professor Jo Boaler, the author of Mathematical Mindsets, concerning why timed math tests amplify math anxiety and turn students, especially girls, away from math. To reform math education, we need to shift the focus to a growth mindset for math and onto achieving deep mathematical understanding.

Jo Boaler: Stanford researcher, professor of math education and author of the acclaimed book, Mathematical Mindsets.

Math anxiety has now been recorded in students as young as five, and timed tests are a major cause of this debilitating, often lifelong condition.

Timed tests evoke such strong emotions that students often come to believe that being fast with math facts is the essence of mathematics.

This misguided emphasis on speed and memorization has resulted in high numbers of students dropping out of mathematics.

Brain research shows us that under the stress of time pressure, working memory can become blocked, leaving students unable to retrieve what they already know.

The blocking of the working memory and associated anxiety is particularly common among higher-achieving students and girls.

When schools make learning math an anxiety-provoking experience, we turn students away.

The best way to learn math facts is to through mathematical activities that focus understanding number relationships.

This authentic understanding is best achieved through taking the time to think deeply about number strategies. which takes time.

Yet, many people believe that mathematics is only about calculating -- and that the best mathematics thinkers are those who can calculate the fastest.

In truth, skilled mathematicians are often slow with math, because they take the time to think carefully and deeply about mathematics.

We need our students to become powerful thinkers
who can make connections, think logically, and solve complex problems.

To achieve this goal, we must shift the focus of math education away rapid calculation and towards deep mathematical thinking and understanding

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.

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.

Probability and statistics on Khan Academy: We dare you to go through a day in which you never consider or use probability. Did you check the weather forecast? Busted! Did you decide to go through the drive through lane vs walk in? Busted again! We are constantly creating hypotheses, making predictions, testing, and analyzing. Our lives are full of probabilities! Statistics is related to probability because much of the data we use when determining probable outcomes comes from our understanding of statistics. In these tutorials, we will cover a range of topics, some which include: independent events, dependent probability, combinatorics, hypothesis testing, descriptive statistics, random variables, probability distributions, regression, and inferential statistics. So buckle up and hop on for a wild ride. We bet you're going to be challenged AND love it!

One of the most famous swords was the Cutlass, used by naval men for centuries but made famous by pirates.
The overall build of the Cutlass made it extremely popular among seafarers in the 17th and 18th centuries.
As a short broadsword, generally around 28 inches in length, the Cutlass was ideal for use on ships, where space was limited.
