MTTC Elementary (103): Mathematics Exam Questions With 100% Correct Answers

MTTC Elementary (103): Mathematics Exam Questions With 100% Correct Answers Objective 1 - answerApply a variety of approaches to interpret and solve mathematical problems in real-world contexts Key to finding solutions - answerGuess and check; making a sketch or a picture; make a table or a chart; making a list; act it out; look for patterns; writing an open math sentence; work backward Guess and Check - answerMake your best guess, then check the answer to see whether it's right. Includes many variations. Making a sketch or a picture - answerDraw an image Make a table or a chart - answerOrganizing information from a problem Makin a list - answerOrganizing information from a problem Act it out - answerLiterally "doing" a problem with physical movement and physical objects Look for patterns - answerAsk "what's happening here?" Writing an open math sentence - answerAn equation with one or more variables, or "unknowns". Work backward - answerStart with answer, figure out problem. Reasonableness - answerAttention to reasonableness may be most crucial to problem-solving success Objective 2 - answerUnderstand mathematical communication and use mathematical technology, symbols, and representations to communicate information. Mathematics - answerFor the most part, a science of precision. Negative numbers - answerThose less than zero. Fractions less than zero are negative numbers too. Absolute value - answerCan be thought of as its distance from zero on a number line. Counting numbers - answerCan be shown by the set (1, 2, 3, 4, . . .). Notice that 0 is not a counting number. Whole numbers - answerCounting numbers, including 0 Integers - answerWhole numbers and their negative counterparts Factors - answerAny of the numbers or symbols in mathematics that, when multiplied together, form a product. Prime Number - answerA number with exactly two whole number factors (1 and the number itself). Composite numbers - answerWhole numbers composed of several whole number factors. 1 - answerNeither a prime or composite number - it only has one whole number factor Multiples - answerWhat are produced when the number is multiplied by counting numbers. Every whole number has an infinite number of multiples. Decimal numbers - answerCertain fractions written in special notation. Order of Operations - answerP.E.M.D.A.S. (parentheses, exponent, multiply, divide, add, subtract) Exponential notation - answerA way to sow repeated multiplication more simply Scientific notation - answerA method for showing numbers using exponents Addends (or addenda) - answerCan be thought of as "parts of addition problems." Sums - answerWhen addends are combined Products - answerWhen factors are multiplied Quotient - answerWhen two numbers are divided, one into the other Equations - answerNOT the same as mathematical expressions - Expressions lack a verb; there is no "equals" Trend - answerPattern over time Logical representations - answerGraphic, numeric, symbolic, verbal Objective 3 - answerUnderstand concepts and skills related to whole numbers, number theory, and numeration, and apply this knowledge in problem-solving contexts. Commutative Property for Addition and Multiplication - answerStates that the order in which addends are added or factors are multiplied does not determine the sum or product.
