Grade 2 Math Unit 7 Thinking Flexibly with Numbers to 999

Unit Unit 7 Thinking Flexibly with Numbers to 999

Content Emphasis/ Big Ideas

In this unit, students extend their understanding of two-digit place value to three-digit place values. They read and write three-digit numbers, demonstrating an understanding of the value of each digit in the number. They use their knowledge of place value to compare three-digit numbers.  Given the larger range of numbers, students also revisit numeric patterns, the data cycle and counting sums of money up to $2.00.

Standards:

  • 2.NS.1 The student will utilize flexible counting strategies to determine and describe quantities up to 200. 

  • 2.NS.2 The student will demonstrate an understanding of the ten-to-one relationships of the base 10 number system to represent, compare, and order whole numbers up to 999.

  • 2.NS.4 The student will solve problems that involve counting and representing money amounts up to $2.00.

  • 2.PS.1 The student will apply the data cycle (pose questions; collect or acquire data; organize and represent data; and analyze data and communicate results) with a focus on pictographs and bar graphs. 

  • 2.PFA.1 The student will describe, extend, create, and transfer repeating and increasing patterns (limited to addition of whole numbers) using various representations.

Skills:

  1. Read Write and Identify 3 Digit Numbers
  2. 10 more/less than a number up to 999
  3. 100 more/less than a number up to 999
  4. Compare and Order whole numbers to 999
