Center Elementary School 

By the end of grade one, students understand and use the concept of ones and tens in the place value number system.  Students add and subtract small numbers with ease.  They measure with simple units and locate objects in space.  They describe data and analyze and solve simple problems.  

NUMBER SENSE

1.0

Students understand and use numbers up to 100.  

1.1

I can count, read, and write numbers to 100.  

1.2

I can compare and put in order the numbers to 100 by using the symbols for less than, equal to, or greater than  (<, =, >).  

1.3

I can show the same number using objects and number sentences (for example 8 = ! !!!!!!! or 2 + 2 + 2 + 2 or 10 – 2). 

1.4

I can count and group objects in ones and tens.  

1.5

I can name coins and tell how much they are worth.  I can make combinations of coins with the same value (for example one dime is worth the same as two nickels).  

2.0

Students demonstrate the meaning of addition and subtraction and use these operations to solve problems.   

2.1

I know by heart the addition facts up to 20 and the subtraction facts that go with them.  

2.2

I understand fact families, and I can use them to solve problems.

2.3

I can tell what “one more than,”  “one less than,” “10 more than,” and “10 less than” means.  

2.4

I can count by 2s, 5s, and 10s up to 100.  

2.5

I know the meaning of addition (putting together or increasing) and the meaning of subtraction (taking away, comparing, and finding the difference).   

2.6

I can solve addition and subtraction problems with one- and two-digit numbers.

2.7

I can find the sum of three one-digit numbers.  

3.0

Students use estimation strategies in computation and problem solving that involve numbers that use the ones, tens, and hundreds places.  

3.1

I can make estimates about numbers that make sense.      

ALGEBRA AND FUNCTIONS

1.0

Students use number sentences with operational symbols and expressions to solve problems.  

1.1

I can write and solve number sentences using addition and subtraction.  

1.2

I understand the meaning of the symbols  +,  -,  =.  

1.3

I can create my own addition and subtraction problems.

MEASUREMENT AND GEOMETRY

1.0

Students use direct comparison and nonstandard units to describe the measurements of objects.   

1.1

I can compare objects using length, weight, and how much an object holds.  

1.2

I can tell time to the nearest hour and half hour.  I can answer time questions about before, after, shorter, or longer.  

2.0

Students identify common geometric figures, classify them by common attributes, and describe their relative position or their location in space.  

2.1

I can name, describe, and compare triangles, rectangles, squares, and circles, and the faces of three-dimensional objects.  

2.2

I can put objects in groups and tell why I am grouping them that way.

2.3

I can give and follow directions about location. 

2.4

I can use words to tell the location of objects (for example, near, far, below, above, up, down, behind, in front of, next to, left or right of)

STATISTICS, DATA ANALYSIS, AND PROBABILITY

1.0

Students organize, represent, and compare data by category on simple graphs and charts.  

1.1

I can name and group objects by the ways they are alike.  I can tell how I have grouped them.  

1.2

I can show information by using pictures, bar graphs, tally charts, and picture graphs.  I can use the terms “largest, smallest, most often, least often” when we talk about them.  

2.0

Students sort objects and create and describe patterns by numbers, shapes, sizes, rhythms, or colors.    

2.1

I can name, describe, and make longer patterns by referring to their shapes, sizes, or colors.   I can do this with rhythm, number, color, and shape patterns.  

MATHEMATICAL REASONING

1.0

Students make decisions about how to set up a problem.  

1.1

I can figure out how to solve math problems and what I need to solve them, such as objects or pencil and paper.  

1.2

I can draw my answers or use objects to solve them.  

2.0

Students solve problems and to justify their reasoning.  

2.1

I can explain my answers to others and why I have solved a problem in that way.  

2.2

I can solve problems and check my answers to make sure that they are right.  

3.0

Students note connections between one problem and another.
