### PRODUCT DESCRIPTION

This Morning Work and Review for 1st Grade Addition & Subtraction (numbers to 20) 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 on the questions in this pack. It is aligned to the Common Core Standards.

This pack can be used as a stand-alone product, or as a supplement to the Singapore Math Math in Focus curriculum. It can also be used to promote higher order thinking where students are challenged to transfer their basic skills to more demanding questions. Deviating from routine practice and drill, this morning review pack focuses on “diagnostic learning”, where students learn from carefully scaffolded questions, instead of “testing”, where students are expected to give a correct exact answer to the questions. The specified item introduced from the Common Core Standards are indicated on each page.

Self assessment, a critical component of independent learning, is also included on every page where students reflect on their progress by answering a simple question, “Do you find this work easy?”. It also provides teachers with a simple feedback on their students’ learning.

Many hours have been spent on the preparation of this morning review pack. We are committed to high quality and engaging math materials and specially designed them to promote both conceptual (why the rules work) and procedural (what are the rules) knowledge. My students have found them useful and enjoyable. I know you will too.

The topics include:
Operations & Algebraic Thinking (1.OA)
Represent & solve problems involving addition & subtraction
A1: Addition and subtraction within 20 to solve word problems
A2: Word problems that call for addition of three whole numbers whose sum is less than or equal to 20
Understand and apply properties of operations and the relationship
B3: Apply properties of operations as strategies to add and subtract.
B5: Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).
C5: Relate counting to addition and subtraction
C6: Add and subtract. Use strategies such as counting on, making ten, relationship between addition and subtraction. Specifically, this set of worksheets uses Singapore Math strategies such as number bonds for addition, subtraction and setting family of number sentences.

Number and Operations in Base Ten (1.NBT)
Extend the counting sequence
A1: Count to 120, read and write numerals and represent a number of objects with a written numeral. (count to 20 in this worksheet)
Understand place value.
B2: Understand that the two digits of a two-digit number represent amounts
of tens and ones. Understand the following as special cases:
a. 10 can be thought of as a bundle of ten ones — called a “ten.”
b. The numbers from 11 to 19 are composed of a ten and one, two,
three, four, five, six, seven, eight, or nine ones.
B3: Compare two two-digit numbers based on meanings of the tens and ones
digits, recording the results of comparisons with the symbols >, =, and <.
