Number Puzzles

Number puzzles are a challenging collection of puzzles in which you have to make all of the numbers within the given range (e.g. 0 through 9) by using only certain integers (e.g. 2,4,6 and 8) and basic arithmetic operations (+, -, and /) along with any combination of parenthesis. The range of numbers is typically 0 through 9 but may be different for some of the puzzles. The constraints on the numbers may be: using only 1,2 and 3 (Easy as 1-2-3) ; using only even integers (Even’s Only); using 5 five times (Five 5’s); to name a few. These puzzles are GREAT practice for order of operations as well as basic number sense. Remember, these can be challenging for younger students but the reward is worth it!
