Students use multiple representations and real-world contexts to support their development of number sense for large numbers. Students use place value charts, number lines, and number sentences to represent numbers to the billions. Students make connections and translate between these representations to compose, decompose, compare, and order large numbers. Students use strategies to estimate quantities and products. They represent numbers with exponents and multiply numbers that are multiples of ten represented as powers of ten.
| EXPECTATIONS | |
|---|---|
| Use this list of expectations to assess students on the key concepts and skills in this unit. | |
| E1 | Read and write large numbers (to the billions). |
| E2 | Compare and order large numbers. |
| E3 | Use strategies to estimate quantities (e.g., rounding, using benchmarks). |
| E4* | Show different partitions of large numbers using a place value chart, number lines, and number sentences (e.g., 10,705 = 10,000 + 700 + 5; 40,879 = 4 × 10,000 + 8 × 100 + 7 × 10 + 9). |
| E5* | Represent numbers with exponents. |
| E6 | Determine the unknown in an equation involving multiple addends. |
| E7* | Multiply numbers that are multiples of ten represented as powers of ten (e.g., 64,320 = 6 × 104 + 4 × 103 + 3 × 102 + 2 × 101 + 0; 300,000 = 3 × 105). |
| E8 | Estimate products. |
| E9* | Demonstrate fluency with multiplication and division facts for the 2s and 3s. |
| * Denotes Benchmark Expectation | |
