A. Rote count up to 31. B. Rote count up to 100. C. Build representations of numbers up to 19 by creating a group of 10 and some 1s (e.g., 13 = one 10 and three 1s). D. Identify the value of the numbers in the tens and ones place within a given number up to 31. E. Compare two digit numbers up to 31 using representations and numbers (e.g., identify more tens, less tens, more ones, less ones, larger number, smaller number). F. Add within 100, including adding a two-digit number and a one-digit number, and adding a two-digit number and a multiple of 10. G.

Mentally add or subtract 10 from a given two-digit number without having to count. I. Mentally add or subtract 10 from a given set from the 10s family (e.g., what is 10 more than 50?
