Grade 1, Quarter 2
Unit 4: Place Value & Building Number Sense
Common Core Standards:
Understand place value.
? 1.NBT.3 Compare two twodigit numbers based on meanings of the tens and ones digits, recording the results of comparisons with the symbols >, =, and <.
?
Use place value understanding and properties of operations to add and subtract.
? 1.NBT.4 Add within 100, including adding a twodigit number, and a onedigit number, and adding a twodigit number and a multiple of 10, 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 and explain the reasoning used. Understand that in adding twodigit numbers, one adds tens and tens, ones and ones; and sometimes it is necessary to compose a ten.
? 1.NBT.5 Given a twodigit number, mentally find 10 more or 10 less than the number, without having to count; explain the reasoning used.
? Reason with shapes and their attributes.
? 1.G.1 Distinguish between defining attributes (e.g., triangles are closed and threesided) versus nondefining attributes (e.g., color, orientation, overall size); build and draw shapes to possess defining attributes.
? 1.G.2 Compose twodimensional shapes (rectangles, squares, trapezoids, triangles, halfcircles, and quartercircles) or threedimensional shapes (cubes, right rectangular prisms, right circular cones, and right circular cylinders) to create a composite shape, and compose new shapes from the composite shape.

Enduring Understanding (Big Ideas):
Enduring understandings go beyond discrete facts or skills. They focus on larger concepts, principles, or processes. They are transferable and apply to new situations within or beyond the subject.
 The location of a number in the place value chart is the determining factor in what the digit represents.
 ? Numbers larger than 10 can be represented in terms of tens and ones.
 ? Sets of tens can be perceived as single sets. The sets can be counted in different ways. For example, 2 tens can be used to describe 20 single objects using the baseten approach.
 ? Place value leads to number sense and efficient strategies for computation.
 ? The properties of shapes make them alike or different.
 ? Equal means being of the same size, quantity, or value.
 ? Understand the meaning of the symbols <, >, and =.
 ? A shape’s characteristics (e.g., triangles are closed and threesided) are used for identification.
 ? Color, orientation, and overall size do not define the shapes.
 ? Threedimensional shapes are combinations of twodimensional shapes.
 ? Twodimensional shapes may be composed of many different shapes.
 ? The properties of shapes make them alike or different.
 ? Some shapes have sides, angles, and faces which can be counted.
 ? Patterns can be created, extended, and transferred through the use of geometric shapes.
 ? Location of shapes can be described using positional words. Equal means being of the same size.

 ? Compose and decompose numbers.
 ? Count forward to 100 from any given number.
 ? Count to 100 by ones and tens.
 ? Understand onetoone correspondence.

Unit 3: Counting, Place Value, & Geometry
Common Core Standards:
Extend the counting sequence.
1.NBT.1 Count to 120, starting at any number less than 120. In this range, read and write numerals and represent a number of objects with a written numeral.
Understand place value.
1.NBT.2 Understand that two digits of a twodigit number represent amounts of tens and ones. Understand the following as special cases:
1.NBT. 2a 10 can be thought of as a bundle of ten ones — called a ?ten.?
1.NBT.2b The numbers from 11 to 19 are composed of a ten and one, two, three, four, five, six, seven, eight, or nine ones.
1.NBT.2c The numbers 10, 20, 30, 40, 50, 60, 70, 80, 90 refer to one, two, three, four, five, six, seven, eight, or nine tens (and 0 ones).
1.NBT.3 Compare two twodigit numbers based on meanings of the tens and ones digits, recording the results of comparisons with the symbols >, =, and <.
Represent and solve problems involving addition and subtraction.
1.OA.2. Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.
Understand and apply properties of operations and the relationship between addition and subtraction.
1.OA.3 Apply properties of operations as strategies to add and subtract. Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11, is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)
Work with addition and subtraction equations.
1.OA.7 Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false. For example, which of the following equations are true and which are false? 6 = 6, 7 = 81, 5 + 2 = 2 + 5, 4 + 1 = 5 + 2.
1.OA.8 Determine the unknown whole number in addition or subtraction equation relating 3 whole numbers. For example determine the unknown number that makes the equation true in each of the equations 8+? = 11; 5 = ___  3; 6 + 6 =___.

 Missing addends may be represented by a variety of symbols (ex. question mark, blank, box, circle, etc.).
 Understand addition as putting together and adding to count, and understand subtraction as taking apart.
 Number relationships provide the foundation for strategies that help students remember basic facts.
