Curated OER
Area of Irregular Polygons
In this geometry worksheet, 10th graders determine the area of irregular polygons. The one page worksheet contains three problems. Solutions are provided.
Curated OER
Cartesian Coordinate System
Students explore the Cartesian coordinate plane and plot points on the graph. They interpret coordinates for a point from the graph and give the ratio of rise over run for slope.
Curated OER
Constructing Tangrams
Seventh graders visualize and identify geometric shapes after applying transformations on a coordinate plane. In this tangrams lesson, 7th graders construct a set of tangrams and then answer extension questions related to measurement,...
Curated OER
Cartesian Coordinate System
Students explore the concept of the coordinate plane. In this coordinate plane lesson, students graph points on the coordinate plane using an applet. Students graph functions using an applet. Students play a Maze Game where they must...
Curated OER
The Function Box
Pupils explore arithmetic and numerical patterns. After observing a teacher created function box, students describe a pattern and predict what will "come out" of the function box. They explore patterns such as geometric shapes,...
Curated OER
Visual Patterns in Tessellations
Students explore tessellations as well as various types of polygon. Students examine tessellating patterns in the world around them. Students examine tessellations by creating their own tessellations and completing the included worksheet.
Curated OER
Repeating Patterns
Learners explore growth patterns by using manipulatives such as pattern blocks, investigate growth pattern of pattern, record growth in T-chart, describe how pattern is growing, and predict number of blocks needed to extend pattern.
Curated OER
Prime and Composite Numbers with use of manipulatives (Elementary, Mathematics)
Students learn what prime and composite numbers are. They learn how to identify them by working in a group and demonstrating an understanding of one work problem with 100% accuracy using the manipulatives provided.
Curated OER
Factors, Divisibility, and Relatively Prime
Seventh graders explore the concept of divisibility. In this divisibility lesson, 7th graders use divisibility rules to find factors of numbers. Students create foldables to illustrate divisibility rules.
Curated OER
Figure This!
Second graders explore the concept of inequalities. They use the mathematical symbols =, <, > to show relationships among numbers. Students devise and use problem solving strategies to explore the situation.
Curated OER
The Function Box
Students look around classroom and identify any patterns they see, describe patterns and explain why they are patterns, use pencil to demonstrate arithmetic patterns by tapping, practice predicting patterns by using Function Box, and...
Curated OER
Perimeters, Patterns, and Conjectures
Students discover patterns and write conjectures relating to perimeters and polygons. Working in cooperative learning groups, they use manipulatives and graphic organizers to solve problems then answer a series of questions in which they...
