Curated OER
Dream Bedroom Floor Plan
Students build and apply concepts of geometry. In this geometry lesson, students create a building using proportions and scale drawings. They use Cabri technology to create a virtual drawing first.
Curated OER
Finding the Area of a Parallelogram with Translations
Students calculate the area of a parallelogram. In this geometry activity, students perform translation using a coordinate plane and coordinate pairs. They perform translation on other polygons.
Curated OER
Finding the Area of a Parallelogram with Translations
Students calculate the area of parallelograms. In this geometry lesson, students identify properties of parallelograms and use to to solve problems. They create polygons using Cabri software.
Curated OER
The Sum of All Angles
Students add up the different angles using the angle addition postulate. In this geometry lesson, students differentiate between interior and exterior angles. They calculate the different angles for triangles and use proof to show their...
Curated OER
Designing a Quilt Pattern
Students create and color a one-patch quilt design based upon a regular hexagon. They examine quilts and photos of quilt designs, read a handout, and complete their quilt design on a worksheet.
Curated OER
Triangle Side Lengths and Angles Measures
Students identify missing sides and angles. In this geometry lesson, students use triangular theorems to identify the missing sides. They use the Pythagorean Theorem to find the different ratios of each side.
Curated OER
Fractions of a Set
Third graders use fractions to describe part of a set. In this fractions lesson, 3rd graders are introduced to fractions through a book and use pattern blocks to describe a fraction as a part of a set. This lesson includes a scripted...
Curated OER
Fractions Describe Parts of a Whole
Third graders represent fractions as part of a whole. In this fractions lesson, 3rd graders use manipulatives to show how a fraction is a part of a whole. This lesson includes individual practice and an assessment instead of direct...
Curated OER
Placing Plates
Second graders investigate the task of making a large hexagonal plate by putting together smaller ones. The lesson has detailed example problems for the teacher to use during direct instruction. The manipulative activities strengthen the...
Curated OER
2-D Geometry
Third graders are introduced to new vocabulary related to Geometry. As each word is mentioned, they demonstrate the word with their body. In groups, they identify the similarities and differences between each line and angle. To end...
Curated OER
Houses
Third graders use a number of problem solving strategies in this unit of lessons. They determine how to draw and model three-dimensional objects, use co-ordinate systems, determine probability of events, and identify paths of simple...
Curated OER
Identifying Angles
Fourth graders examine the various characteristics of angles. In groups, they identify angles in the real world and which angles are used for buildings. To end the lesson, they use their bodies to represent the different angles for a...
Curated OER
Trigonometry
Eighth graders practice calculating the unknown length of a right angle triangle. They also examine the pythogoram theory in groups. They help each other work through the problems.
Curated OER
Geometry: 3D Objects
In this math worksheet, learners examine 4 pictures of 3D objects and write the name of each. Students then study 3 pictures and figure the number of faces, edges and vertices on each.
Curated OER
ndirect Measurement Technique: Using Trigonometric Ratios
Ninth graders find the height of an object that would be difficult or impossible to measure directly. They construct and use a Clinometer to measure the angle of elevation (or depression). Students create a sketch of the measurement...
Curated OER
Peter's String
Students are introduced to the math problem and consider how they could approach it. In pairs, students investigate Peter's conjecture in any way they see fit. They then share their answers with the class.
Curated OER
Topics in Math
In this consumer mathematics worksheet, students explore a variety of topics in mathematics including simple interest, perimeter, area, volume, translating words into symbols, percentage problems and mortgage calculations. The fourteen...
