 Students need to: Use one-to-one correspondence and rote counting to determine how many objects are in a set of up to 10 objects. Verbally count to 10 by ones and then develop rote counting to 20 by ones. Understand the relationship between numbers and quantities to 10. Recognize that the last number name said tells the number of objects counted. Identify, describe, and create sets of up to 10 objects using concrete materials (ten frames), pictures and/or numerals (with 0 representing a count of no objects). See numbers 6 – 10 with a 5 group (dot arrays, fingers, ten frame). Match a numeral to a set 0-10. Recognize written numerals 0 – 10. Count and discuss quantity 0-10 in various arrangements (line, array, scattered). Recognize the concept of just after or just before a given number in the counting sequence up to 10. Use one-to-one correspondence to identify, describe, and compare sets of concrete objects using language such as “more than,” “less than,” or “same as”. Recognize that each successive number name refers to a quantity that is one larger. Say the number-word list to thirty-nine.
