Math Kindergarten Quiz Composing and Decomposing Numbers 11-19-K.NBT.A.1

CCSS.MATH.CONTENT.K.NBT.A.1 delves into the foundational understanding of the numbers 11 through 19. It emphasises that these numbers are made up of “ten ones” and a certain number of additional ones. For example, the number 12 is composed of ten ones and two more ones. This understanding aids in the comprehension of place value and is an integral aspect of early mathematics education. Using objects, drawings, or equations can facilitate this understanding.
