- What are the three phases of the concrete-representational-abstract (CRA) sequence in mathematics instruction?
- 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?
- Physical manipulatives such as blocks, counters, fraction bars, or base-ten pieces
- What is computational fluency?
- The ability to quickly and accurately perform basic arithmetic operations
- What are equivalent fractions?
- 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?
- A common denominator
- What is a bar model or tape diagram used for in elementary mathematics?
- Solving word problems by visually representing the relationships between quantities
- In the number 4,582, what value does the digit 8 represent?
- 80, or eight tens
- What is place value decomposition?
- 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?
- Equal groups arranged in rows and columns, showing the repeated addition structure of multiplication
- How does a fraction bar help students understand fractions?
- 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?
- Comparing numbers, showing distance, counting, and solving addition and subtraction problems
- What does checking for reasonableness in problem-solving mean?
- Determining whether an answer makes sense by rounding and performing rough calculations
- What is the expanded form of a number?
- 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?
- 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?
- Changing the order of addends does not change the sum, such as 4 plus 7 equals 7 plus 4
