2.NBT.A.1
2.NBT.A.1
Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones; e.g., 706 equals 7 hundreds, 0 tens, and 6 ones. Understand the following as special cases:
2.NBT.A.2
Count within 1000; skip-count by 5s, 10s, and 100s.
2.NBT.A.3
Read and write numbers to 1000 using base-ten numerals, number names, and expanded form.
2.NBT.A.4
Compare two three-digit numbers based on meanings of the hundreds, tens, and ones digits, using >, =, and < symbols to record the results of comparisons.
2.NBT.A.1a
2.NBT.A.1a
100 can be thought of as a bundle of ten tens — called a “hundred.”
2.NBT.A.1b
The numbers 100, 200, 300, 400, 500, 600, 700, 800, 900 refer to one, two, three, four, five, six, seven, eight, or nine hundreds (and 0 tens and 0 ones).
