Holocaust Education and World Languages
Students use poetry to share their feelings about the Holocaust. Using the internet, they research a major event of the twentieth century from a different viewpoint using the language of the foreign country. They use different...
Curated OER
Fold and Cut
Second graders explore line symmetry and the names and attributes of two-dimensional mathematical shapes. They study the context by folding and cutting out shapes to make a series of mathematical shapes.
Curated OER
Pattern Matching
First graders examine how to determine the lines of symmetry in pictures, shapes, and patterns by completing the lessons in this unit. They make patterns that show a line of symmetry and describe it using their own language.

Mirror, Mirror on the Wall
Learners utilize their observational skills. They explore body movements and facial clues of their partner and imitate them. Students practice and perform in front of the class. They write a story with a mirror as a major feature.
Curated OER
Geometry Scavenger Hunt
Pupils use the digital camera, identify geometric shapes (in nature as well as man-made), and gain a better understanding of geometric vocabulary. They search for and recognize geometric shapes in unusual settings
Curated OER
Area of Parallelograms
Seventh graders review the process of finding the area of a rectangle and complete a couple of examples as a class. They discuss what a parallelogram is and what the formula would be for finding its area. They listen to an explanation...
Curated OER
Strawberry Milk
Students work in groups or alone to solve the problem. They use a systematic approach to get all possible answers. They report back to the class with solutions. They may extend their studying using a crate with room for 9 bottles.
Curated OER
Lots of Squares
Students work in pairs, to make a square on the geoboards with a rubber band (or draw one on the dot paper). It can be any size and in any location and share their answers with the class.
Curated OER
Symmetry In Nature
Students investigate the symmetry that is found in nature. They view shapes and patterns in nature while looking at images. Students look for tessellations while obtaining photographs with a digital camera. The information is used for...
Curated OER
Piecing Together the Puzzle
Students examine tikkun olam. For this religion lesson, students define the concept of tikkun olam and identify actions that they can do to help make the "perfect world." Students share ideas and post their ideas on the class web.
