For this triangles worksheet, learners problem solve and shade triangles within other triangles. Students complete two problems.
Curated OER
Descriptive Writing
Learners practice descriptive writing. In this unique writing lesson, students hear a story about a mitten. Then three grade levels come together to first, create a mitten on KidPix; second, describe the designed mitten; and third, try...
Curated OER
Fold and Cut 2
Second graders make, name, and describe, using their own language and the language of geometry, everyday shapes and objects. They create and discuss geometric patterns which repeat (show translation), or which have rotational or...
Curated OER
Performing Transformations
Students investigate the concepts relating to creating a tessellation. They include using pattern blocks in order to create interconnecting patterns. Students review translations, rotations, and reflections.
Curated OER
Compatible numbers to 20
Students practice theories dealing with equals sign used as a balance, inequality symbols and practice utilizing a box or some other geometric shape to represent an unknown number. They assess numeracy problems embedded in language-rick...
Curated OER
What Does It Take?
First graders study the attributes of circles, squares, triangles and rectangles. They sort shapes that are the same and those that are different into groups.
Curated OER
Keeping the Pioneers Warm
Fourth graders are introduced to some of the history and background of the art of quilt making by 19th century pioneer women. They use tagboard shapes to design, construct and display quilt squares.
Curated OER
Copycats
Third graders describe the features of 2 and 3 dimensional objects and use the language of geometry. They design and make a pattern which involves translation, reflection or rotation.
Curated OER
Turn Symmetry
Fourth graders observe geometric patterns to determine if they show rotational or point symmetry. They participate in the a demonstration lesson with a triangle. They create their own designs that show rotational or point symmetry.
Curated OER
Let's Make Lemonade Lesson 3: What's the Big Idea?
Students examine and decide on a service-learning project to perform. They design and execute posters that advertise the project using geometric shapes.
Curated OER
Science: Water States
First graders investigate the various forms of water. They discuss the properties of water. They discover examples of water's various states and locate other solids, liquids, and gases in their homes.
Curated OER
Japanese music
Pupils explain music in relation to history and culture. They explore "Tanko Bushi."
Curated OER
Variations
Sttudents examine populations of living things and identify variations in physical features.
Curated OER
Anecdotes from Artifacts
Students use clay to create a personally meaningful and symbolic artifact. They interpret the artifacts in writing and read about the use of symbols in Native American art.
Exploratorium
Disappearing Act
Crafty critters are camouflaged to escape predators, and crafty science pupils can construct a camouflage demonstration. They work with a partner to show that as a camouflaged animal moves, it becomes more visible.
Curated OER
The Periodic Table of the Elements
High schoolers investigate the origin of the modern periodic table of elements, and explore an interactive version that teaches them how to extract information from it.
Curated OER
Making the Connection: Math and Architecture
Taking a walk around you town center can turn into a lesson about math and architecture.
Inside Mathematics
Graphs (2006)
When told to describe a line, do your pupils list its color, length, and which side is high or low? Use a worksheet that engages scholars to properly label line graphs. It then requests two applied reasoning answers.
Curated OER
Picture It-Fractions
Third graders draw pictures of fractions and label them with the correct fractional amount.
Curated OER
Line: a Geometric Exercise
Students study the different types of lines and create a drawing demonstrating what they learned.
