- What are the three phases of the concrete-representational-abstract (CRA) sequence in mathematics instruction?
Show answer
Concrete (using manipulatives), representational (using pictures and drawings), and abstract (using symbols and numbers)- What teaching tools are most important in the concrete phase of the CRA sequence?
Show answer
Physical manipulatives such as blocks, counters, fraction bars, or base-ten pieces- What is computational fluency?
Show answer
The ability to quickly and accurately perform basic arithmetic operations- What are equivalent fractions?
Show answer
Fractions that represent the same value or amount, even though they have different numerators and denominators- Before adding fractions with unlike denominators, what must you find?
Show answer
A common denominator- What is a bar model or tape diagram used for in elementary mathematics?
Show answer
Solving word problems by visually representing the relationships between quantities- In the number 4,582, what value does the digit 8 represent?
Show answer
80, or eight tens- What is place value decomposition?
Show answer
Breaking a number into its individual place values to simplify computation, such as 234 equals 200 plus 30 plus 4- What does an array represent in multiplication instruction?
Show answer
Equal groups arranged in rows and columns, showing the repeated addition structure of multiplication- How does a fraction bar help students understand fractions?
Show answer
It shows parts of a whole and demonstrates how many equal parts make up the total- What concepts can a number line be used to teach in elementary mathematics?
Show answer
Comparing numbers, showing distance, counting, and solving addition and subtraction problems- What does checking for reasonableness in problem-solving mean?
Show answer
Determining whether an answer makes sense by rounding and performing rough calculations- What is the expanded form of a number?
Show answer
Writing a number as the sum of the value of each digit, such as 347 equals 300 plus 40 plus 7- What does a fact family show in mathematics?
Show answer
Related facts, such as the addition and subtraction facts (3+5=8, 5+3=8, 8-3=5, 8-5=3) or multiplication and division facts- What is the commutative property of addition?
Show answer
Changing the order of addends does not change the sum, such as 4 plus 7 equals 7 plus 4
