Math Expectations
Addition, Subtraction and the Number System
Represents and solves addition and subtraction word problems within 20
 Uses objects, drawings, and equations to represent the problem
 Solves word problems that call for addition of three numbers within 20
Uses flexible strategies to add and subtract within 20. Demonstrates fluency (accurate and efficient) to add and subtract within 10
 Use properties of operations to add and subtract. For e.g., if 8 + 3 = 11, then 3 + 8 = 11
 Understands that addition can be used as a strategy to subtract (Example: 11  8 could be solved by thinking 8 + ? = 11)
Reads, writes and counts objects up to 120 starting at any number less than 120
Represents and compares two digit numbers based on the meaning of the tens and ones digits
Uses place value understanding and properties of operations to add and subtract within 100
 Adds a two digit and a one digit number using models or drawings
 Adds a two digit and a multiple of ten using models or drawings. (Ex: 38 + 20)
 Mentally (without having to count) finds 10 more or 10 less than a given two digit number
 Subtracts a multiple of ten from another multiple of ten between 10 and 90 using concrete models or drawings (Example: 80  50)
Accurately measures and compares the lengths of up to three objects
Geometry
Reasons with shapes and their attributes
 Distinguishes between defining attributes (a triangle has three sides) versus nondefining attributes (color)
 Uses 2  D shapes or 3  D shapes to make new shapes
 Partitions circles and rectangles into two and four equal parts. Describes the parts using the words halves, fourths and quarters
