Learning Objectives Identify the tens and ones place in a two-digit number. Represent a number up to 100 using base-ten blocks. State the value of a digit in the tens place (e.g., the 4 in 45 is 40). State the value of a digit in the ones place (e.g., the 5 in 45 is 5). Draw a model of a two-digit number using sticks and dots. Count groups of tens and ones to find a total number.
