Fractions of a Set
Third graders use fractions to describe part of a set. In this fractions instructional activity, 3rd graders are introduced to fractions through a book and use pattern blocks to describe a fraction as a part of a set. This instructional...
Curated OER
Looking For Triangles
Students solve problems with triangles. In this geometry lesson, students analyze shapes to find different triangles. They name the shapes created by putting triangles together.
Curated OER
No-Three-In-A-Line Again
Learners interpret information and results in context while using words and symbols to generalize patterns. They use symmetry and angle properties of polygons to solve practical problems and identifying invariant properties under...
