Curated OER
Space Geometry
Students explore points, lines and planes as it relates to geometry. In this geometry activity, students analyze space and explain wy it is 3-D and not flat or 2-D. They solve problems involving volume and 3-D shapes.
Curated OER
Cartesian Coordinates
Students investigate rational numbers through data analysis and statistics. For this algebra lesson, students represent, rename, compare and order rational numbers. They collect and represent data correctly on a graph.
Curated OER
"Geometry With Quilts"
Fifth graders examine the geometry of quilts. They discuss the history of quilting, design two nine-patch squares, exchange one design on an Internet bulletin board, and construct a hot pad that is quilted.
Curated OER
Rotation Symmetry
Pupils investigate the concept of symmetry by using various examples and performing independent practice with scaffolding provided by the teacher. They review reflection symmetry and cover the new rotation symmetry using manipuatives.
Curated OER
Perfect Places!
Second graders study the decimal point and study tenths, hundredths, and thousandths. They explain ways to read and write decimals.
Curated OER
It's Close Enough: Rounding and Estimation
Second graders round to the closest five, ten, and hundred. They use place-value concepts of grouping based upon powers of ten (thousandths, hundredths, tenths, ones, tens, hundreds, thousands) within the decimal number system.
Curated OER
Picket Fence Around the Garden
Learners design different shaped plots and determine the perimeter, area and shape of each. They compare the shapes that have the same area but may have different perimeters.

"One Hundred Hungry Ants" by Elinor J. Pinczes
Students identify arrays and write multiplication and division problems to match. They write their own multiplication book using arrays.
Curated OER
Cookie Mining
Students investigate mining and economics. In this mining activity, students play a game in which they purchase property, mine the property, and pay for reclamation. Students earn money for each ore mined.
Curated OER
Perimeter and Area of a Rectangle
Sixth graders fill out worksheets to find the perimeter and area of rectangles. In this perimeter and area lesson plan, 6th graders color in the area and measure the perimeters.
Curated OER
Understanding Rational Numbers and Proportions
Students explore parts of a whole. In this fraction lesson, students determine what makes a fair share. Working with manipulatives, students solve mathematical problems containing fractions.
Curated OER
"If You Hopped Like a Frog" by David M. Schwartz
Students search for and generalize an algebraic pattern. They make and analyze a coordinate graph.
Curated OER
ExplorA-Pond:4th Grade Surface Area
Fourth graders estimate the surface area of a pond using the chance method and the estimation method. They complete a graph and a short report comparing the results of the two methods.
Curated OER
Grandfather Tang's Story
Students recognize, describe, and perform transformations (rotation/turn, reflection/flip, and translation/slide) on two dimensional shapes.
Curated OER
Facial Tattoos or Face Painting
Students use a grid-like method to create a life-size self-portrait from a 3X5 black and white photo. They explore the different customs and rituals surrounding face painting from ancient through modern civilizations. Students create a...
Curated OER
Discovering Growth Patterns
Students explain the differences between linear (arithmetic) and exponential (geometric) growth. They use worksheets imbedded in this lesson plan to help them make predicitions and graph data points.
Curated OER
Plant Systems
Students examine plant systems. For this life science lesson, students explore leaf and root systems on paper in a terrarium that they design and construct.
Curated OER
Two for One Box Company
Eighth graders experiment to decide if a box that is twice as big holds twice a much. They work the concept of volume and how changing dimensions affect it.
Curated OER
Measure Me!
Third graders use nonstandard concrete methods to estimate and record measurements of their body.
Curated OER
Atlas Scavenger Hunt
Young scholars discover what type of information in an atlas by participating in a scavenger hunt. With a partner, they try to find the answers to many questions as possible. They exchange their papers with another partner group and...

The Pythagorean Theorem
Seventh graders relate the Pythagorean theorem to the real world. In this algebra lesson, 7th graders identify important properties of the Pythagorean theorem and use it to solve word problems. They create a step by step plan to...
Curated OER
Centimeter Slinkies
Third graders estimate and measure the length of a whole color-segmented, candy gummy worm. Then, as students bite off each segment, they estimate, measure and record findings in an activity log.
