Placing a Fire Hydrant
Triangle centers and the segments that create them easily become an exercise in memorization, without the help of engaging applications like this lesson. Here the class investigates the measure of center that is equidistant to the three...

Symmetry in Children's Art Experiences
Read between the lines of symmetry to make important connections between math, art, culture, and nature.
Curated OER
Symmetry that is Basic and Beautiful
Young scholars explore lines of symmetry. In this symmetry instructional activity, students divide and combine shapes along basic lines of symmetry. Young scholars explore symmetry in real life objects.
Curated OER
Tangrams
Learners construct tangram pieces. Then they make observations and explore patterns with the pieces.

Exploring Similarity Using Scale Drawings
Learners explore scale factor as they create a scale drawing of a box, then determine the surface area and volume of the original and the scale drawing. The one page worksheet contains activities and procedures with four questions.

Quadratic Equations and Parabolas
Students graph and solve quadratic equations. In this functions lesson, students analyze a quadratic equation using three points on a curve to define the graph of a quadratic function. They find the vertex and intercepts of the graph.

Analyzing 3-D Shapes and 2-D Representations
Students can analyze 3-D objects better with actual physical models and by also drawing 2-D representations of them.

Find Someone
Your class will participate in a series of math vocabulary activities to learn about parallel lines. They find people using a math list and connect math words in the context of sentences. They also read the math words in the example...
Curated OER
2D Polygons and 3D Nets
Students compare and contrast two dimensional polygons and three dimentional nets by examining the differences in drawings. They create three dimensional shapes and label the faces, edges, and vertices. After creating the shapes, they...

Symme"tree"
Young scholars practice drawing lines of symmetry after the teacher draws shapes on the board. They create a class symme"tree" using only symmetrical shapes to decorate it.
