General Resources 
Building Set: K'Nex Elementary Math and Geometry KitThe K'NEX® Education Elementary Math & Geometry set allows students to build, investigate and explore geometry concepts, vocabulary, and structures in a 2D and 3D world. The students live in a 3D world, so it makes sense for them to connect with geometry on a 3D level. K'NEX® allows them do just that!
The teacher's guide, designed as a resource, provides a glossary of key terms and definitions and includes Vocabulary Card masters to support instruction and understanding. The activities are standards based and designed around best practices in mathematics instruction. They build upon one another as they lead students towards a greater understanding of mathematics and geometric concepts. Set includes 142 K'NEX® parts – enough to build 38 K'NEX® Math models. Support 34 students working as a team. Grades 1  3. Building instructions and teacher's guide aligned to national standards and Common Core Mathematics included. Packaged in a strong storage tray with snapon lid.

ITunes App: Symmetry School: Learning Geometry
Geometry, the mathematics of shape and space, is a fun and practical way to introduce mathematical thinking, and Symmetry School encourages learners to use their intuition and imagination to explore symmetrical puzzles. Through gameplay, learners are aided in developing an essential foundation in spatial reasoning, problem solving and visualization.
• Learn to recognize reflective and rotational symmetry. • Use an understanding of reflective symmetry to complete the missing half of a pattern. • Use an understanding of rotational symmetry to predict and describe the results of rotating patterns. • Recognize simple spatial patterns and relationships and make predictions about them. • Develop a foundation for understanding symmetry at later levels. • Solve problems and learn to work systematically. • Develop fine motor skills. • Have fun and learn! ITunes App: Shape ArtsCan you make a mermaid, a spaceship or a fierce shark with just 7 shapes? Go furry, aquatic, spiky or stumpy  your shape creations can be anything you imagine!
Build geometry skills, creativity and problemsolving in this fun educational app for age 7+. FEATURES √ Make shape puzzles for others to solve √ Hundreds of new puzzles to play √ See how many times puzzles are solved √ Collect marbles as you progress √ Works online and offline √ Save a photo of your work √ No inapp purchase LEARNING Immerse kids in rich visual thinking about shapes and their properties. → Math Skills: geometric thinking, spatial visualization and spatial rotation skills → Math Knowledge: 2d shapes, shape attributes, rotation, symmetry, angles → Learning Skills: reasoning, problemsolving, creativity, making and sharing ITunes App: My Geometric Universe
Your child can use the pencil, ruler, compass and set square to draw lots of different geometric shapes! The shapes can then be cut out and used to build real objects! Once these objects have been created, they can be placed in any of the three magical universes: The Kid's Room, Ancient Egypt or the Middle Ages.
Chocolapps apps promote your child's development because they help to improve observation and concentration skills, and give your child a sense of independence.
