Mathematics Grade 2
Strand: NUMBER AND OPERATIONS IN BASE TEN (2.NBT)
Understand place value (Standards 2.NBT.1–4)
. They use place value understanding and properties of operations to add and subtract (Standards 2.NBT.5–9)
Read and write numbers to 1,000 using base-ten numerals, number names, and expanded form.
Grade 2 Math Module 3: Place Value, Counting, and Comparison of Numbers to 1,000 (EngageNY)
In this 25-day Grade 2 module, students expand their skill with and understanding of units by bundling ones, tens, and hundreds up to a thousand with straws. Unlike the length of 10 centimeters in Module 2, these bundles are discrete sets. One unit can be grabbed and counted just like a banana-1 hundred, 2 hundred, 3 hundred, etc. A number in Grade 1 generally consisted of two different units, tens and ones. Now, in Grade 2, a number generally consists of three units: hundreds, tens, and ones. The bundled units are organized by separating them largest to smallest, ordered from left to right. Over the course of the module, instruction moves from physical bundles that show the proportionality of the units to non-proportional place value disks and to numerals on the place value chart.
Grade 2 Unit 1: Extending Base Ten Understanding (Georgia Standards)
In this unit, students will understand the value placed on the digits within a three-digit number, recognize that a hundred is created from ten groups of ten, use skip counting strategies to skip count by 5s, 10s, and 100s within 1,000 and represent numbers to 1,000 by using numbers, number names, and expanded form, compare two-digit number using >, =, <.
Looking at Numbers Every Which Way
This task gives students the opportunity to work with multiple representations of base-ten numbers. The standard asks students to read and write numbers to 1000 using base-ten numerals, number names, and expanded form. This task addresses all of these and extends it by asking students to represent the numbers with pictures and on the number line.
