Describing and Creating Plane Figures - Grade One
Young mathematicians draw, create, and describe different shapes using triangles. They discuss attributes of the original and created shapes. Pupils classify the created shapes and draw and write in mathematics journals to communicate...
Curated OER
Tantalizing Tangrams
Fourth graders participate in what is considered to be a model lesson plan. The lesson plan focuses upon polygons and basic geometry. The lesson plan addresses national standards and displays how others should be done.

Slides, Flips. Turns......It's All On A Memory Book Page
Fourth graders use tangram sets to investigate the congruence of shapes. They use congruent shapes to demonstrate the properties of slides, flips, and turns. They complete a math journal entry that describes and illustrates each concept.
Curated OER
Transformations
Several practice exercises suitable for any geometry class working on transformation, symmetry, and tessellation -- especially visual representations of image translation, rotation, and reflection, symmetry, tessellations and tangrams --...

Geo Jammin' By DeSign - Day 2, Lesson 9: Bringing It To A Fine Gloss-ary
Students create a glossary of geometric terms while exploring tangram manipulatives.
Curated OER
It Counts
Learners assign numbers to describe objects. In this number lesson, students assign numbers to objects and compare more, less, and equal values. They write down descriptions of plants including the number of leaves and height of the...
Curated OER
Fun Times with Integrals
Students study techniques used for solving integrals. Using tangrams and hands-on activities, students perform basic integration techniques. They use artistic skills and real-world applications to discover more complex methods of...
Curated OER
Classifying Polygons
Students study polygons. In this math instructional activity, students play a game in which they learn the classification system for polygons. Students identify the properties of quadrilaterals.
Curated OER
Transformations-Translations
Students perform transformations and translation on a coordinate plane. In this geometry lesson, students move shapes around on a graph identifying translation, image, and transformation. This lesson has an interactive part online that...
Curated OER
It Counts
Students explore one to one number correspondence. In this early math activity, students make observations about and classify plants in order to gain an understanding of using numbers to describe their world.
