Students represent, read, write, compose, and decompose whole numbers through 100,000 using standard, expanded, and word forms, identify digit places and values through the hundred-thousands place, and model numbers through 1,000 with base-ten blocks. They count forward and backward by 1s, 10s, 100s, and 1,000s, skip-count by 2s, 3s, 4s, 5s, 6s, 8s, 9s, and 10s, locate missing numbers and whole numbers on number lines through 1,000, and compare or order numbers through 100,000. They round whole numbers to the nearest 10 and 100 and estimate quantities using benchmarks such as 10, 100, and 1,000.
