Place Value for Whole Numbers
Fourth graders, in groups, explore place value for whole numbers. They explore how to use base-ten materials to make sense of place value in the tens and ones column. They also explore whole-number patterns by using base-ten materials.
Curated OER
The Corner Problem
Young scholars explore the concept of the corner problem. In this corner problem lesson, students use the TI-NSpire to determine the maximum length a rod can be and still pass horizontally around a corner. Young scholars use similar...

Exploring Trigonometric Ratios
Students identify the ratios of trig functions. In this trigonometry lesson, students construct triangles and use it to derive the values of sine, cosine and tangent. They use Cabri software to create the visual of the identities.
Curated OER
Exploring the Hinge Theorem
Students explore the application of Hinge Theorem. In this geometry lesson plan, students write inequalities, given two sides of a triangle. They solve problems with triangular inequalities using the proper theorem.
Curated OER
Composition of Reflections
Students perform reflections and translations of polygons. In this geometry lesson, students perform reflection in two parallel lines. They use Cabri to observe the transformation and rotations of each shape.
Curated OER
Exploring Special Lines
Learners compare and order numbers. In this geometry lesson, students write equations for inequalities. They differentiate and apply concepts of triangular properties to solve problems.
