Understand addition, and understand subtraction. CCSS.Math.Content.K.OA.A.1 Represent […]

The Common Core – Counting and Cardinality Pt. 3

The 3rd part of the first standard focuses on comparison greater than, less than, or equal to (the same). Compare numbers. CCSS.Math.Content.K.CC.C.6 Identify whether the number of objects in one group is greater than, less than, or equal to the number of objects in another group, e.g., by using matching and counting strategies.1 CCSS.Math.Content.K.CC.C.7 Compare two numbers […]

The Common Core- Counting & Cardinality Pt. 2

The second Domain in the area of Counting & Cardinality is divided into 2 main standards as described below. Count to tell the number of objects. CCSS.Math.Content.K.CC.B.4 Understand the relationship between numbers and quantities; connect counting to cardinality. CCSS.Math.Content.K.CC.B.4a When counting objects, say the number names in the standard order, pairing each object with one and only […]
