"Sweet Clara and the Freedom Quilt" by Deborah Hopkinson
Students create paper quilts of their own using the isometric grid that tessellates the plane or the fraction quilt square.
Curated OER
Golden Connections
Students determine the ratio of pairs of consecutive terms in the Fibonacci Sequence. Using four different colors, they create a golden rectangle in either two or three dimensions. They use photographs to create two collages using...
Curated OER
Snowflake Curve
Learners develop an appreciation for complex structures in nature. They observe patterns in nature in relationship to the Real World. Students use observation skills to assist in problem solving. They show comprehension of the concepts...
Curated OER
Fractals Forever or Obvious and Hidden Order
Students discuss ways computers use properties of similar figures to generate scale models and create scenes. they describe patterns they have seen on a fern, pineapple, or pinecone. Students research Benoit mandebrot, H. von Koch and...
Curated OER
Dynamic Collages and Assemblages
Students create a two, three, or four-dimensional collage or assemblage. They use shapes, colors, images, objects, and textures to create their collage.
Curated OER
Ratios (Cost of a Habit)
Learners consider an individual habit and its cost. They study ratios and proportions, and use that knowledge to calculate the cost of a habit over extended periods of time. write a detailed comparison of the costs.
Curated OER
Fraction Equivalence
Fourth graders explore fractions. They compare different fractions using fraction bars. Students find equivalent fractions and they use fraction bars to visualize addition of fractions.
Curated OER
The Mandelbrot Set
Students explore the Mandelbrot Set. They are introduced to the concept of a complex number and function in order to motivate the discussion of Julia and Mandelbrot sets. Students investigate fractals and how they are built.
Curated OER
Angles and Arcs
Students discuss the sum of central angles and use string to create them on circles. They find the measure and length of both minor and major arcs.
Students give examples of concentric, similar, and congruent circles and congruent arcs.
Curated OER
Day #8 - Fractals
Students explore fractals and draw fractal curves. To assist in remembering the methods, they sing a song about fractals, watch a video, and create images of fractals on dot paper. Students observe and discuss a comic strip about...
Curated OER
Geo-Town
Second graders use a checklist to construct a Geo-Town map including a compass rose, a map key, and a paragraph about a walk around Geo-Town, using appropriate geometric and directional vocabulary to identify the two-dimensional figures...
Curated OER
Properties of Fractals
Students build a working definition of regular fractal, look carefully at the concepts of dimension and scale, and are introduced to logarithms. They solve simple exponential equations for the exponent both by trial and error and using...
Curated OER
Inscribed Angles
Students analyze inscribed angles and intercepted arcs and explore the relationships between the two. They investigate the properties of angles, arcs, chords, tangents, and secants to solve problems involving circles.
Curated OER
Using the Variation Approach
Young scholars explore and explain geometrical applications, and how to apply these applications to real life.
Curated OER
Properties of Fractals

Curated OER
Minerals
Students explore the concept of minerals. In this minerals lesson, students discuss how cooling affects the size of crystals. Students discuss how the structure of minerals is a tetrahedron. Students discuss the structure of silicates...
Curated OER
Geometric Glossary
Fourth graders use drawing and paint tools to identify, draw and state several geometric terms.
Curated OER
Round to the Nearest Whole $
In this rounding money worksheet, students identify the money amounts in each examples and round to the nearest dollar for the 10 examples.
Curated OER
Polygons and Angles
Sixth graders estimate the measurement of angles and then measure the exact distance using an angle ruler. In groups, they explore shapes and recognize the characteristics acute, obtuse and right angles. Students sketch required shapes,...
Curated OER
"How Many Snails?" by Robert Wells
Students represent algebraic patterns in various ways.
Curated OER
Distortion Unleashed
Students view examples of man-made structures and create a building that matches the style. Using the internet, they research the style of Frank Lloyd Wright and create plans for creating their own community. They use a painting of...
Curated OER
Space Shapes
Learners read "Captain Invincible and the Space Shapes" by Stuart Murphy and view a PowerPoint presentation on shapes. They identify shapes presented in the book and then identify shapes found in their classroom.

Congruent Triangles - Is This Enough Information?
Seventh graders examine congruence postulates and apply knowledge to triangles in the world around them.
Curated OER
Months
First graders work in pairs to create a class big book for months of the year. They work together to create a detailed version of their month that includes any special holidays and activities.
