Understand and Use Place Value
SCAFFOLDS
SUPPORTS
Develop an understanding of whole number relationships and place value including grouping in tens and ones. Extend the counting sequence to 120 (1.NBT.1). Understand that the digits of a number represent the amount of ones and tens (1.NBT.2). Compare two two-digit numbers (1.NBT.3). Use place value understanding to add and subtract a two-digit number and either a one-digit number or a multiple of ten adding tens to tens and ones to ones (1.NBT.4), (1.NBT.5.), (1.NBT.6).
Students use objects or drawings to compose and decompose numbers 11–19 to gain foundations for place value (K.NBT.1)
Mathematical Tasks

SUPPORTS
: Order and compare lengths of three objects (1.MD.1). Develop an understanding of linear measurement and measuring lengths as copies of same-length units. Measure lengths indirectly by laying copies of an object end to end and express the measurement as a whole number (1.MD.2).
