### PRODUCT DESCRIPTION

**TeachableMath.com**

This Morning Work and Review for “2nd Grade Place Value and Addition to 1000” has been especially designed to promote deep learning, using tested strategies from the Singapore Mathematics curriculum. It focuses on Algebraic Thinking; which is a recurring theme in this pack. It is aligned to the Common Core Standards.

*****************
Supports Math-in-Focus Singapore Mathematics Curriculum
Chapter 1: Numbers to 1,000
- Counting
- Place Value
- Comparing Numbers
- Order and Pattern

- Addition with Regrouping in Ones
- Addition with Regrouping in Tens
- Addition with Regrouping in Ones and Tens

*****************
This pack can be used as a stand-alone product, or as a supplement to the Singapore Math Math in Focus curriculum. It is designed to promote higher order thinking and logic skills, deviating from routine drill and practice. It also encourages alternative problem solving from carefully scaffolded questions. Many studies have shown that students exposed to multiple approaches since young become better math solvers in later years.

Place value understanding is a crucial cornerstone in arithmetic. This morning work, with its emphasis on number sense, is specially designed to promote both conceptual (why the rules work) and procedural (what are the rules) knowledge. Students are challenged to transfer their basic skills to more demanding problem solving.

*******************
Common Core Standards include:
Number and Operations in Base Ten (2.NBT)

Understand place value.
1. Understand that the 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. Count within 1000; skip-count by 5s, 10s, and 100s.
3. Read and write numbers to 1000 using base-ten numerals, number names, and expanded form.
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.
Use place value understanding and properties of operations to add and subtract.
5. Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.
6. Add up to four two-digit numbers using strategies based on place value and properties of operations.
7. Add and subtract within 1000, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method. Understand that in adding or subtracting three-digit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones; and sometimes it is necessary to compose or decompose tens or hundreds.
8. Mentally add 10 or 100 to a given number 100–900, and mentally subtract 10 or 100 from a given number 100–900.
9. Explain why addition and subtraction strategies work, using place value and the properties of operations.
