Students create a glossary of geometric terms while exploring tangram manipulatives.
Curated OER
It Counts
Students 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 lesson, students play a game in which they learn the classification system for polygons. Students identify the properties of quadrilaterals.
Curated OER
Transformations-Translations
Learners 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 lesson, students make observations about and classify plants in order to gain an understanding of using numbers to describe their world.
