Standard 1.NSN.2 - Practice skip counting forward and backward from a specific number to complete the sequence.

Included Skills:

Counting
• demonstrate, using concrete materials, the concept of one-to-one correspondence between number and objects when counting;
• count forward by 1's, 2's, 5's, and 10's to 100, using a variety of tools and strategies (e.g., move with steps; skip count on a number line; place counters on a hundreds chart; connect cubes to show equal groups; count groups of pennies, nickels, or dimes);
• count backwards by 1's from 20 and any number less than 20 (e.g., count backwards from 18 to 11), with and without the use of concrete materials and number lines;
• count backwards from 20 by 2's and 5's, using a variety of tools (e.g., number lines, hundreds charts);
• use ordinal numbers to thirty-first in meaningful contexts (e.g., identify the days of the month on a calendar).
