Number Puzzles Deluxe app for iPhone and iPad

Number Puzzles Deluxe is a collection of virtual manipulative challenges that requires students to arrange numbers to make equal sums .

There are 5 puzzles in this collection. The puzzles are appropriate for elementary age students but fun for anyone who enjoys math puzzles. The object is to place numbers from 1 to 9 in a pattern so that the sum along each line of the design is the same. For example, in one puzzle students place numbers along the sides of an equilateral triangle so that the sum is equal to one of three different numbers.

Each puzzle requires a different logical strategy. Because the app is design to simulate a table top with manipulative, students are encouraged to experiment.

There is educational value in just letting students play with the puzzles and do the mental arithmetic involved in finding the sum, thus, reinforcing addition skills. Teachers will find it beneficial to have students verbalize the mathematical thinking and logical reasoning that they are using to solve the puzzle.
