The Challenge Question
A research position becomes a modeling job. The introductory lesson in a series of nine presents the challenge of analyzing a set of bivariate data. The class brainstorms what the data may represent. Pupils must decide what is needed to...
Insurance Zebra
Insurance Curriculum for Middle and High School Teachers
Liability, deductible, premium ... what do these words mean, and how do they relate to insurance? Scholars complete a pre-test, matching vocabulary activity, and insurance timeline worksheet and become familiar with these terms. Next,...
Curated OER
Mapping a Site Using a Coordinate Plane
Learners map their playground as if it were an archeological site. They locate objects on the playground and determine their location using coordinate points. A related lesson is Coordinate Grid: Mapping an Archeological Site.
Curated OER
Shapes from Shapes
Geometric shapes are really cool. Examine triangles, quadrilaterals, trapezoids, rhombuses, parallelograms, pentagons, and hexagons with your class. They draw large shapes and small shapes then compare them to understand their shapely...
Curated OER
Graph Paper Patterns
Young artists divide a piece of graph paper into sections using rectangles, squares, and triangles. They then fill each section with patterns of shape and color. Elementary graders describe how their patterns are organized. Secondary...
Curated OER
Investigation - Looking For Triangles
Seventh graders investigate a series of triangles, looking for patterns and generalizing what they have found. They analyze the pattern data and organize it into a table and graph. Students identify the relationship and discover the rule...
Curated OER
How's The Weather?
Students make a box and whiskers plot using the TI-73 graphing calculator. Each student would have their own calculator but they would work in small groups of two or three to help each other enter the data and make the plots.

The Counting Caterpillar
A daily counting routine builds a caterpillar with 100 body segments (marked with symbols to indicate 2s, 5s, and 10s) by the 100th day of school. Provides structured repetition as part of the morning routine so that by 100th day,...

The Multiplicative Identity and Numbers Close to One
Pupils practice multiplying and dividing whole numbers by fractions. They study the multiplicative identity property that states that the product of any number and 1 is that number. They multiply whole numbers by fractions close to 1 and...
Curated OER
Comparing Fractions
The best way to teach students how to compare fractions is using visual means. This instructional activity suggests a variety of ways to help learners understand this concept using a SMART Board, Kidspiration, videos, computer games, and...
Curated OER
Shapes in Our World
Help your learners explore shapes. They classify shapes and identify them in their everyday world. Plane shapes are explored, and they classify and identify the plane shapes.
Curated OER
Ancient American Art and Geometry
Students explore the relationship between geometry and ancient American art. They see how to recognize geometric properties in specific works and explain how these properties contribute to their meaning and artistic merit.
Curated OER
Pop-it...Stop-it
Students observe how certain geometric shapes can be used to make some structures rigid and others flexible. The activity involves construction of a 30-60 right triangle, folding while following directions, and identifying polygons.
Curated OER
Westward Expansion
Students locate California and New York on a map and explore available means of travel in the 19th century. Students explore the role of trade in pioneer America and simulate various barter transactions.
Curated OER
Twists and Turns
Learners reflect, rotate, translate, and dilate figures in the Cartesian coordinate plane using grid paper and dot paper. They use transformations (i.e., reflections, translations, rotations, and dilations) to describe geometric patterns...
Curated OER
Backwards Writing: Reflections and Symmetry
Why is "ambulance" written backwards on emergency vehicles? Young geometers apply principles of symmetry to translate words written backwards. See if your school or district subscribes to Jobland, where you can view a clip that explains...
Curated OER
Equivalent Fractions
Introduce elementary students, grades 3-5 to the concept of equivalent fractions. Each student folds a paper in half and color one of the equal parts of the paper. They use this paper to define numerator, denominator and the idea that a...
Curated OER
Measurements: Inches
Children solve problems involving measurement using information taken from various items measured (wooden blocks and boxes). This is a particularly good lesson to use when introducing how to use a ruler and how to add inches together in...
Curated OER
Clay Tile: Art Deco Style
Students analyze and classify sets of pictures using a mathematical classification system and create original works of Art Deco tiles using this new knowledge and four types of symmetry.
Curated OER
"NSN, Fractions, Percents, Ratios, Rates" Investigations
Sixth graders engage in an investigation about the concepts related to fractions. They read, represent, compare, and order proper and improper fractions, and mixed numbers. They demonstrate an understanding of relationships involving...

Mars Fraction Hunt
Learners use fractions and words to find a coded message and the first student to solve the message wins a candy bar.
Curated OER
Interactive Fractions
Learners determine the common denominator of two unlike fractions. They practice adding fractions and finding equivalent fractions of numbers. They compare and contrast different types of equations involving fractions and construct...
Curated OER
Geometric Figures and Applications
High schoolers study geometric figures. They use graph paper or Geometer's Sketchpad to construct and decorate geometric shapes, and also create a 3-D polygon using construction paper and a given template.
