By the end of kindergarten, students understand small numbers, quantities, and simple shapes in their everyday environment. They count, compare, describe and sort objects, and develop a sense of properties and patterns. Students understand the relationship between numbers and quantities (i.e., that a set of objects has the same number of objects in different situations regardless of its position or arrangement). Students understand and/or describe:

• Addition
• Subtractions
• Estimation
• Ones and tens places
• Time
• Weight
• Length
