456 is, in fact, less than 500 because 456 has four 100 s (a four in the hundred’s place) and some tens and ones that total less than one hundred, while 500 has five 100 s (a five in the hundred’s place). True. It reads, “Four hundreds and 9+3=12 ones is less than 491 .” 12 ones is the same as one ten and three ones, so let’s rewrite the previous sentence. “Four hundreds, one ten, and two ones is less than 491 .” 412<491 412 is, in fact, less than 491 . Although both numbers have four 100 s (fours in the hundred’s place), 412 only has one ten (a one in the ten’s place), while 491 has nine tens (a nine in the ten’s place). False. It reads, “Three hundreds and four tens is less then seven tens, nine ones, and two hundreds.” 340<279 340 is, in fact, greater than 279 because 340 has three 100 s (a three in the hundred’s place), while 279 has two 100 s (a two in the hundred’s place). False. It reads, “Seven ones and three hundreds is greater than 370.” 307>370 307 is, in fact, less than 370 . Although both numbers have three 100 s (threes in the hundreds place), 307 has no 10 s (a zero in the ten’s place), while 370 has seven 10 s (a seven in the ten’s place). False. It reads 2 hundreds + 7 tens = 3 hundreds - 2 tens 270=280 While both numbers have 2 hundreds (a two in the hundreds place), 270 has 7 tens (a seven in the tens place) while 280 has an 8 in the tens place. Therefore 270<280 2.NBT Comparisons 2 Alignment 1: 2.NBT.A.4 Domain NBT: Number and Operations in Base Ten Cluster Understand place value.
