• Represents and solves word problems involving addition and subtraction within 100 

• Is fluent with addition and subtraction facts to 20 

• Works with equal groups of objects to gain foundations for multiplication (e.g., arrays, repeated addition, etc.)

• Understands place value (e.g., ones, tens, hundreds, thousands) 

• Skip counts 5’s, 10’s, and 100’s within 1000 

• Reads and writes numbers to 1000 using numerals, expanded form, and words

• Compares three-digit numbers based on place value using >, =, < symbols 

• Uses multiple strategies to add and subtract double digit numbers within 100 

• Adds and subtracts within 1000 using models, strategies, and drawings 

• Explains why addition and subtraction strategies work

• Measures, estimates, and compares the lengths of objects in standard units 

• Represents addition and subtraction on a number line 

• Tells and writes time from analog and digital clocks to the nearest 5 minutes using a.m. and p.m. 

• Solves word problems involving dollar bills, quarters, dimes, nickels, and pennies using $ and ¢ correctly 

• Represents and interprets data on line plots, picture graphs, and bar graphs

• Recognizes and draws shapes according to given attributes (e.g., number of angles, number of faces) 

• Identifies triangles, quadrilaterals, pentagons, hexagons, and cubes 

• Divides a rectangle into equal squares and finds the total number 

• Divides circles and rectangles into equal pieces (2, 3, or 4), and describes the whole as two halves, three thirds, or four fourths

• Recognizes that equal parts of identical wholes do need to be the same shape

Students are able to “stick with” problems and will try multiple methods to reach a solution.

Students understand that written numerals represent real world objects and quantities.

Students are able to explain their own mathematical ideas and strategies and they respond to the thinking of others.

Students use pictures, objects, numbers, and/or words to express their mathematical thinking and reasoning.

Students select the appropriate tools and resources to solve a problem.

Students use detailed and accurate mathematical vocabulary to communicate mathematical understandings.

Students notice attributes and structures in mathematics such as: sorts shapes by the number of sides or recognizes that 4+6=10 and 6+4=10.

Students identify patterns, make predictions and use repetitive actions that support computation: 12 + 5 is the same as 10 + 2 + 5.
