The parents' guide to what's in this app.

Educational Value

Kids can learn about three-dimensional shapes including prisms, regular polyhedrons, solids of revolution (like cylinders), and pyramids. For each shape, kids can learn about its attributes (including number of vertices, edges, and faces) and rotate the shape to view it from all angles. Kids also learn the formulas for area and volume, and then apply these formulas in the assessment exercises. The augmented reality feature is an excellent real-world application and teaches kids to identify everyday objects that have geometric shapes. While it's probably not a tool kids will delight in using, especially outside the context of a geometry class, Arloon Geometry is a powerful and innovative resource.

Ease of Play

Instructions only given for augmented reality feature, but most kids should be able to easily figure out how to use all of the features. Formulas will only make sense to kids who have already studied them.

What parents need to know

Parents need to know that Arloon Geometry is a comprehensive learning tool that teaches and assesses kids' knowledge about three-dimensional shapes. Kids can explore different shapes' attributes as they rotate and unfold them into flat figures or use the augmented reality feature to explore them in 3-D. Formulas for finding surface area and volume are included. In-app languages include English and Spanish.

What's it about?

ARLOON GEOMETRY offers two options that kids can choose from: Learn or Exercises. Kids select Learn to explore shapes, which are organized into categories based on their attributes. Once kids tap on a category, they choose a shape and read about it, watch it unfold into a two dimensional shape, learn formulas for finding its area and volume, and use the augmented reality feature: Kids can either use printed cards from the website or a well-defined graphic to make the AR figure appear using the device's camera. Kids select Exercises to assess what they've learned via the Guess, True/False, and Calculation activities. Kids or adults can customize based on category of shapes, properties, time allowed for assessment, number of exercises, and number of characteristics. Feedback is minimal, and kids' scores are only tracked as they are working on the exercises.

Is it any good?

Providing both instruction and assessment, this augmented reality-enhanced tool allows kids to interactively explore three-dimensional shapes. It's best for kids who already have some background in geometry, as the shapes and concepts begin at an intermediate level. In conjunction with a geometry class or a deep interest in structural design, this tool gives kids access to a variety of ways to approach the material, but it's definitely not one that most kids will want to dive into and revisit on their own.

Talk to your kids about ...

  • Families can talk about three-dimensional shapes in every day life. Identify the prisms and polyhedrons in your home.

  • Help kids customize the exercises to focus on content in small chunks.

  • Encourage kids to create their own 2-D shapes that fold up into 3-D structures.
