Welcome to the Times Table Shuffle application. This app consists of a series of self-checking multiplication and division puzzles. It provides students of all ages with a novel and exciting way to practice apply and reinforce their multiplication and division skills in finding common factors common denominators and factor pairs which are essential to the mastery of fractions mental arithmetic (i.e. without reliance on the calculator) and problem solving.

There are three levels of difficulty all playable on the Android devices and tablets.
The levels are as follows:

Level 1.) Table range 2 to 7 times for the small grid. Table range 2 to 10 times for large grid
recommended for players from grades 2 to 4

Level 2.) Table range 2 to 12 times
recommended for players from grades 4 and up

Level 3.) Table range 5 to 15 times
recommend for advanced players

How to play:

1.) Choose a grid size a level of difficulty and quick game or full game

2.) Use the products shown as clues on the grid to determine the row and column multipliers on the left and top edges of the grid respectively.
