Daily UI #004 Calculator

Here is my Daily UI #004: Calculator. I created a children's calculator concept app based off the vintage "Fisher Price Sesame Street Cookie Counter" from the 80's. Here's a shot of the "Add" function, when the user enters the correct answer, in this case 7, seven cookies fall across the screen announcing they were right! There are other functions, Subtract, Count, Quiz, and Calculator that help a child learn basic math skills.

I'm new to the UI/UX design world, I'm hoping the Daily UI Challenge will be a great way to improve my skill sets!
