Grade 3 - Number

Standard 3.N.1.1 - Compare and sort numbers from 1 to 120, arranging them in order from least to greatest or greatest to least.

Included Skills:

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)
