# Ocean-Themed Math for K-12

May 23rd, 2022

It’s Monday, May 23, 2022, and time for Math at ClickSchooling!

Bureau of Ocean Energy Management: Tidepool Math

This website has FREE math lessons and activities that are themed around ocean tidepools.

When you get to the website you can choose between a Tidepool Math Curriculum for Grades K-8 or High School.

• K-8 – This curriculum provides lessons and exercises to help students become familiar with tidepool habitats. Students use math skills such as counting, estimation, and determining the mean, to learn how the intertidal environment constantly changes both physically and biologically.

• High School – This curriculum is divided into three parts with lessons and exercises that use science and math to provide the student with increased awareness of the diversity of animals and plants in intertidal habitats. It helps students understand the differences between random, systematic and targeted sampling approaches as well as comparing estimates, counts, and means. Through the activities, students gain an understanding of how to use simple statistical concepts and tools to analyze and study environmental data.

Both of the curriculums are offered through downloadable PDFs. The exercises refer to photos of tidepools and marine animals and plants that are provided for free on the website as well.

You can also download and print out colorful flashcards of marine animals and plants. Each card has a terrific illustration on the front, with scientific information and cool facts on the back – similar to what you’d find in a field guide.

While this curriculum is interesting and engaging all on its own – a trip to the beach or an aquarium with a tidepool exhibit would be a great way to enhance the learning.

# Examine the Artwork of M.C. Escher

National Gallery of Art: M.C. Escher – Life and Work

All grades; children with parental supervision

The National Gallery of Art sponsors this site that offers a virtual tour of the artwork of M.C. Escher.

If your students have studied math tessellations they may have been introduced to some of Escher’s work already — as he used patterns of interlocking forms and architectural mazes in his artwork. He also created unusual spatial effects by drawing a picture from different perspectives, for instance, looking up and down at the same time. Escher really contributed to the idea of metamorphosis drawing where one shape or object turns into something completely different. This tour offers examples of all of these aspects of his work and most kids will find the “morph” prints and drawings especially fascinating.

When you get to the site you can read the “Overview” for a biography and explanation of Escher’s work. Then click on the right arrow to view all of the many works in this virtual gallery. Each piece of art comes with a text explanation that helps the viewer to appreciate what they are looking at.

# The Life & Times of Archimedes

Archimedes

This site is a treasure trove of information on one of the greatest mathematicians of all time – Archimedes. The site was created by Chris Rorres, a Professor Emeritus of Mathematics at Drexel University in Pennsylvania. It contains free information about the life and times of Archimedes, as well as examples of his work and inventions such as the compound pulley system, the planetarium, the water screw, etc.

When you get to the site you’ll see a menu and some fascinating “Quick Facts” about Archimedes. Click on any menu item to explore:

• Archimedes’ Claw
• Burning Mirrors
• The Golden Crown
• Archimedes Screw
• Archimedean Solids
• Spheres and Planetaria
• The Lever
• and much more!

Each item includes an explanation along with illustrations and animations. The documentation and resources for further exploration are terrific. Professor Rorres also indicates which inventions were arguably credited to Archimedes.

This site is a great blend of math and history and may springboard interest in learning much more.

# Tying Knots & Math Together

Ropers Knots Page

This ad-supported, archived website provides a free directory of instructions with illustrations on how to tie knots. You’ll discover how to tie hitches, loops, and other specialty knots for sailing, camping, and more.

When you get to the website, you’ll see a menu of knot instructions and a way to search for knots alphabetically by name. Then just click on the one that interests you – and get step-by-step, illustrated directions on how to tie the knot.

This site also contains links to many, many other knot sites created by scouting organizations, fishermen, artists and more. (Note: We did not review these other sites – parental supervision is suggested.) There’s even a series of websites devoted to math and knot tying.

Oh, and you’ll find a link to learn how to tie a man’s tie as well.

Note: Because this is an ad-supported site where ads are randomly generated – it’s impossible to predict if the advertising on any given page is suitable for children. Parents, as always, should preview and then review the site with their children.

Have fun!

# Practice Math & Feed The Hungy

FreeRice.com: Math

Test your Multiplication Tables and Basic Math (Pre-Algebra) skills and earn food for the hungry!

Scroll down to Math and choose from:

• Multiplication Table
• Basic Math – PreAlgebra
• Derivatives
• Geometry

Click on your choice to get to the quiz. FreeRice automatically adjusts to your level of ability as you take each quiz. It starts by giving you math equations at different levels of difficulty and then, based on how you do, assigns you an approximate starting level. You then determine a more exact level for yourself as you play. When you get a math problem wrong, you go to an easier level. When you get three problems in a row right, you go to a harder level. This one-to-three ratio keeps you challenged to encourage learning.

You can set your own level and you can even have the site remember your total from the last time you were there if you create an account.

And, with every right answer, you donate ten grains of rice through the UN World Food Program to help end hunger. This is made possible by the sponsors who advertise on this site.

The site has expanded to include quizzes in other subjects:

• English
• Geography
• Humanities
• Language Learning
• Science
• And more

If you have more questions, check out the About section. This is a fun and ingenious idea that will motivate kids to practice math while helping others.
