The Castle Learning Math Content Team has released new questions that are aligned to the Common Core standards 6.EE.1 and 6.EE.2. The question types in this release are multiple choice, fill-in-the-blank, matching, and drag-and-drop questions.
- 6.EE.1 – Write and evaluate numerical expressions involving whole-number exponents.
- 6.EE.2 – Write, read, and evaluate expressions in which letters stand for numbers.
- 6.EE.2A – Write expressions that record operations with numbers and with letters standing for numbers. For example, express the calculation “Subtract y from 5” as 5 – y.
- 6.EE.2B – Identify parts of an expression using mathematical terms (sum, term, product, factor, quotient, coefficient); view one or more parts of an expression as a single entity. For example, describe the expression 2 (8 + 7) as a product of two factors; view (8 + 7) as both a single entity and a sum of two terms.
- 6.EE.2C – Evaluate expressions at specific values of their variables. Include expressions that arise from formulas used in real-world problems. Perform arithmetic operations, including those involving whole-number exponents, in the conventional order when there are no parentheses to specify a particular order (Order of Operations). For example, use the formulas V = s3 and A = 6s2 to find the volume and surface area of a cube with sides of length s = ½.
Sample tasks that students are asked to complete:
- Evaluate and reason with exponential expressions.
- Order exponential expressions from least to greatest.
- Write, read, and evaluate expressions in which letters represent numbers.
- Translate verbal expressions into algebraic expressions.
- Identify parts of terms and expressions.
