Students use both area and perimeter to work with geometric shapes.
Students find the area of parallelograms by using square units and the area formula.
Students use the area formula for rectangles to solve real world and mathematical problems.
Students find the area of a trapezoid by decomposing it into triangles and using the formula
How far do I have to walk in order to make 1 mile? Students measure, add, and figure it out.
Students create line plots and analyze data using measurement data with quarter unit fractions.
Connect new measurement knowledge and skills to the students' immediate environment.
Students build measuring skills using quarter inch measurements.
I can create things that have their own unique perimeter.
This lesson focuses on the addition measurement of perimeter using real world examples.
Perimeter is all around us!
A farmer needs a fence to keep the bunny out of his lettuce patch, but does he understand perimiter enough to buy the right amount?
Rectangle is SO MUCH like triangle! Those darned angles--they'll get beginning learners! This is a fun way to practice rectangle!
Subtraction problems can involve shapes, attributes and perimeter.
I can create polygons and find the perimeter by using the unit squares on my paper
This book is a "flexed" version of CK-12's Basic Geometry that aligns with College Access Geometry and contains embedded literacy supports. It covers the essentials of geometry for the high school student.
CK-12 Foundation's Geometry FlexBook is a clear presentation of the essentials of geometry for the high school student. Topics include: Proof, Congruent Triangles, Quadrilaterals, Similarity, Perimeter & Area, Volume, and Transformations.
