Phrase the quotient of 4 and some number a number divided by 2 the ratio of 8 and some number the quotient of a number and 12 Some examples of common phrases and corresponding expressions that involve two operations are: There are so many words that you come across when you're working on algebra problems, and these words are really code for very specific mathematical symbols.
FAQ Puzzles Mathematical puzzles take on a central role in Transition to Algebra as a device to develop problem-solving expertise and stamina and to undo a brittle and rule-bound perception of mathematics that many students bring and that gets in the way of their solving unfamiliar problems.
View a printable sample page of our puzzles. Or click the iPuzzle tab above form information and access for our puzzle apps. Mobile Puzzles typically present multiple balanced collections of objects whose weights must be determined by the puzzler.
These are essentially pictorial representations of systems of several simultaneous equations in two or more variables.
Such puzzles thereby help students simultaneously grasp the concept and role of a variable and develop the logic of algebraic manipulation.
Gradually, shapes are replaced with variables, strings of shapes are replaced by algebraic expressions, and finally sections of mobiles are translated into equations. Truth Puzzles require students to deduce reliable games for writing algebraic expressions from statements whose truth value is not initially known.
Much of mathematics is about figuring out when, or whether, a statement is true or false. The ability to determine the truth value of statements is essential to understanding if a number is a solution of an equation or if a point is on a graph.
Truth puzzles are a familiar staple of recreational mathematics, here presented as the stories of strange little creatures called Beebos. Beebos in the Liar family always lie. Beebos from the Truthteller family always tell the truth, no matter what. Order Puzzles present clues that are, in effect, systems of simultaneous inequalities about age, height, location, and so on, from which students must determine the order of a set of objects or answer questions about the position of one element, the relationship between two elements, or which element s might be in a particular position.
As with the truth puzzles, students are generally drawn to explain how they know what they know and consequently develop language to explain their reasoning.
Four piano students—Ashley, Brandon, Cassie, and Damian—will give a recital. Cassie insists on playing immediately after Brandon. Damian and Ashley are playing the same piece, so at least one other player must come between them. Help their teacher figure out in what order to have them perform.
Puzzles are another variant of number-line-based puzzles.
These evolve into various two-dimensional Where-Am-I? Puzzles give clues about a multi-digit mystery number that students try to identify.
These puzzles build working memory and the ability to coordinate multiple pieces of information and draw logical conclusions.

They also strengthen academic and mathematical vocabulary as well as the interpretation of symbolic language. The mathematical content of puzzle clues can include place value, divisibility, primes, parity, squares, magnitude, and so on. Mystery Number Puzzles present systems of equations or inequalities in a fun context that focuses on finding solutions not through rules but by reasoning logically about the properties of numbers and operations.
Alone or in combination, the clues place restrictions on the values of the variables to help focus on these properties. The integer-only variety shown here specifies certain numbers that can be written—in this case only 1, 2, 3, and 4—and follows a Sudoku-like rule that no number can be repeated in any row or column.
Using only that operation, the numbers that may be written within the cells of that cage must exactly reach the target. The solution is unique, but there are many ways to start.
For example, the bottom left cage requires that 9 be made by multiplication. Therefore the only allowable numbers that will work are 3, 1, and 3, with the 1 in the corner.Mathfox - Sign up for more fun games by Grade - Preschool to 7th Grade - Click here.
