Describing and Creating Plane Figures - Grade One
Young mathematicians draw, create, and describe different shapes using triangles. They discuss attributes of the original and created shapes. Pupils classify the created shapes and draw and write in mathematics journals to communicate...
Curated OER
Identifying and Classifying Solid Figures
Learners identify and classify solid geometric figures. In this geometry instructional activity, students bring in objects that look like solid shapes and identify their attributes. Learners identify the number of surfaces and faces on...
Curated OER
Plane Figures
Fifth graders create polygons requested by their teacher. In this polygons lesson, 5th graders watch a video and listen to a song about polygons. Then, students take turns labeling various polygons and practice making polygons.
Curated OER
Congruent Shapes
First graders view congruent shapes on a white board and define what congruent means. For this congruent shapes lesson, 1st graders recognize which shapes are congruent and which aren't Students complete a giant worksheet in...
Curated OER
Classifying and Measuring Angles
Fifth graders explore the three types of angles. In this math lesson plan, 5th graders estimate the measure of angles and draw the angles using a protractor.

Classifying Figures on the Coordinate Plane
Fifth graders use estimation to solve word problems. In this fractions lesson, 5th graders decide whether or not an answer to a work problem is reasonable by applying their knowledge of fractions, decimals and estimation. This lesson...
Curated OER
Lines, Segments, and Rays
Fifth graders use their arm, toothpicks, and marshmallows to create lines, segments, and rays. In this lines, segments, and rays lesson plan, 5th graders learn how these appear on a plane.
Curated OER
Meet the Polygon Family
Fourth graders investigate regular polygons. In this regular polygon instructional activity, 4th graders explore the attributes of different polygons. Students work in groups to complete a KWL chart regarding polygons.
Curated OER
Finding the Area of a Parallelogram with Translations
Learners calculate the area of a parallelogram. In this geometry lesson, students perform translation using a coordinate plane and coordinate pairs. They perform translation on other polygons.
Curated OER
Math: Symmetry and Similarity
Pupils describe the differences between congruence and similarity. After explaining the motions that indicate congruency of two shapes, they complete worksheets to draw lines of symmetry and similar shapes. With straws and twist ties,...
Curated OER
Math: Shapes and More Shapes
Students locate lines of symmetry in regular polygons and predict the number of lines of symmetry in an octagon. In three different polygons, they construct all lines of symmetry and after making their prediction about the octagon,...
Curated OER
Polydron Fun
Students investigate nets as they relate to volume and area. In this geometry lesson, students use nets as a visual to deepen their understanding of surface area and volume of objects. They make conjectures about different objects and...

High School Mathematics Geometry Vocabulary Word Wall Cards
Having a good working knowledge of math vocabulary is especially important for geometry learners. Here are 119 pages worth of wonderfully constructed definitions, constructions, formulas, properties, theorems, and postulates. This is a...
Curated OER
Translating Transformations in Geometry
Young scholars create an image using given coordinates and evaluate how the coordinates change when a slide or rotation takes place.
Curated OER
Getting Familiar with Fractals
Students use the Internet to answer lab questions about fractals, and then construct fractals using the initial stage and iteration rule. They complete tables and generate rules for the "nth" term and create their own fractals.
Pennsylvania Department of Education
Problem Solving with Fractions
Solve story problems using fractions or decimals. Then, determine the reasonableness of answers using estimation.The detailed lesson includes essential questions, vocabulary, a materials list, and links to related units.
Curated OER
Shapetown
Students identify basic geometric shapes. In this geometry lesson, students read the book Shapetown and identify the various shapes from the story. Students are given a sheet and draw part of a town using only shapes.
Curated OER
Fractions Describe Parts of a Whole
Third graders represent fractions as part of a whole. In this fractions lesson plan, 3rd graders use manipulatives to show how a fraction is a part of a whole. This lesson plan includes individual practice and an assessment instead of...
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.
