Owlet: GlowGrid app for iPhone and iPad

Owlet: GlowGrid is one of a series of apps that use the Owlet GlowBoard manipulative. The specific focus of GlowGrid is using the GlowBoard to understand arithmetic operations like addition and subtraction. Students turn the dials on the GlowBoard to model arithmetic operations with the colored lights. The GlowGrid app communicates in real time with the GlowBoard, so the app reflects student work with the GlowBoard.

GlowGrid has five modes for five arithmetic operations: Addition, Subtraction, Multiplication, Division, and Division with Remainders.

Each operation has five different activities.
- Explore: Students turn the dials to model arithmetic equations on the GlowBoard. The tablet shows the students the equation that they are modeling.
- Make: The app challenges students to use the operation to make a target number in different ways, i.e. Make 11 in 9 different ways.
- Solve: The app challenges students to solve arithmetic problems with the GlowBoard.
- Find: The app challenges students to solve missing number problems with the GlowBoard.
- Create: Students can create their own problem and use the GlowBoard to demonstrate the solution.
