Unit 7 Place Value Add & Subtract Pt.2

Content Emphasis/ Big Ideas

In this unit, students build on their knowledge of three-digit numbers and explore how those understandings extend to six-digit numbers. Students will estimate, represent, solve and justify three digit one and two step addition and subtraction problems including those in context.

Standards:

3.NS.1 The student will use place value understanding to read, write, and determine the place and value of each digit in a whole number, up to six digits, with and without models.
3.CE.1 The student will estimate, represent, solve, and justify solutions to single-step and multistep problems, including those in context, using addition and subtraction with whole numbers where addends and minuends do not exceed 1,000.
3.PFA.1 The student will identify, describe, extend, and create increasing and decreasing patterns (limited to addition and subtraction of whole numbers), including those in context, using various representations.
