Second Grade Math Drill

This is a simple math drill but with multiple reward animations.
There is no sound. Only button clicks are required for answers.
The problem types are addition, subtraction, missing addend, sequences, comparing numbers, base 10 blocks, fractions,
2D and 3D geometrical shapes, telling time, fractions, bar charts, measurement and Venn diagrams. Problems become
more difficult as the number of correct answers increases.
The child can view the number of correct answers, shown with an emoji for each one.
If the child enters an incorrect answer, a hint image appears.
On a settings page (for adults but with no restrictions) children may be added by name and assigned a
level 1 - 3. The name, level and the number of correct answers are stored on your device for future sessions.
The app is free, and there are no ads. No Wi-Fi or cell signal is required.
