Essential Questions:
Unit 2 instructional time is focused on these priority standards:
2.NBT.A.2 Count within 1000; skipcount by 5s, 10s, and 100s.
2.NBT.A.3 Read and write numbers to 1000 using baseten numerals, number names, and expanded form.
2.NBT.A.4 Compare two threedigit numbers based on meanings of the hundreds, tens, and ones digits, using >, =, and < symbols to record the results of comparisons.
SAMPLE assessment items for 2.NBT.A
2.NBT.B.6 Add up to four twodigit numbers using strategies based on place value and properties of operations.
2.MD.C.7 Tell and write time from analog and digital clocks to the nearest five minutes, using a.m. and p.m.
2.MD.C.8 Solve word problems involving dollar bills, quarters, dimes, nickels, and pennies, using symbols appropriately.
Unit 2 instruction is supported by these standards:
2.OA.C.3 Determine whether a group of objects (up to 20) has an odd or even number of members, e.g., by pairing objects or counting them by 2s; write an equation to express an even number as a sum of two equal addends.
2.NBT.A.1 Understand that the three digits of a threedigit 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:
a. 100 can be thought of as a bundle of ten tens  called a "hundred."
b. 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).
 How does the place of a digit determine its value?
 The position of a digit determines its value.
 An understanding of place value allows children to compare the numbers. When comparing 73 and 22, for example, 7 tens is greater than 2 tens, therefore, 73 is greater than 22.
