number concepts to 1000 • counting: - skip-counting by any number from any starting point, increasing and decreasing (i.e., forward and backward) - skip-counting is related to multiplication - investigating place-value based counting patterns (e.g., counting by 10s, 100s; bridging over a century; noticing the role of zero as a placeholder 698, 699, 700, 701; noticing the predictability of our number system) • Numbers to 1000 can be arranged and recognized: - comparing and ordering numbers - estimating large quantities • place value: - 100s, 10s, and 1s - understanding the relationship between digit places and their values, to 1000 (e.g., the digit 4 in 342 has the value of 40 or 4 tens) - understanding the importance of 0 as a place holder (e.g., in the number 408, the zero indicates that there are 0 tens) • instructional resource: Math in a Cultural Context, by Jerry Lipka
