Compare two or more sets of objects (up to ten objects in each group) and identify which set is equal to, more than, or less than the other.
Count, recognize, represent, name, and order a number of objects (up to 30).
Know that the larger numbers describe sets with more objects in them than the smaller numbers have.
Use concrete objects to determine the answers to addition and subtraction problems (for two numbers that are each less than 10).
Recognize when an estimate is reasonable.
Identify, sort, and classify objects by attribute and identify objects that do not belong to a particular group (e.g., all these balls are green, those are red).
Demonstrate an understanding of concepts of time (e.g., morning, afternoon, evening, today, yesterday, tomorrow, week, year) and tools that measure time (e.g., clock, calendar).
Name the days of the week.
Identify the time (to the nearest hour) of everyday events (e.g., lunch time is 12 o'clock; bedtime is 8 o'clock at night).
Identify and describe common geometric objects (e.g., circle, triangle, square, rectangle, cube, sphere, cone).
