Unit 2: Place Value, Counting, and Comparison of Numbers to 1,000
Essential Questions:
These are questions we are working on answering during Unit 2. At the end of the unit, students should be able to answer the essential questions:
How does place value help us understand larger numbers?
Why is place value important?
Curriculum:
Number Talks
Eureka Math
Priority Standards we will be focusing on in Unit 2:
2.NBT.1 Understanding that 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.
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).
2.NBT.2 Count within 1000; skip-count by 5’s, 10’s and 100’s
2.NBT.3 Read and write numbers to 1000 using base-ten numerals, number names, and expanded form.
2.NBT.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.
