count
1.1 Count, read, and write whole numbers to 100.

compare and rank
1.2 Compare and order whole numbers to 100 by using the symbols for less than, equal
to, or greater than (<, =, >).

inverse operations
1.3 Represent equivalent forms of the same number through the use of physical mod
els, diagrams, and number expressions (to 20) (e.g., 8 may be represented as 4 + 4,
5 + 3, 2 + 2 + 2 + 2, 10  2, 11  3).

estimate and round
1.4 Count and group object in ones and tens (e.g., three groups of 10 and 4 equals 34,
or 30 + 4).

Money
1.5 Identify and know the value of coins and show different combinations of coins that
equal the same value.



add and subtract
2.0 Students demonstrate the meaning of addition and subtraction and use these
operations to solve problems:
2.1 Know the addition facts (sums to 20) and the corresponding subtraction facts and
commit them to memory.

inverse operations
2.2 Use the inverse relationship between addition and subtraction to solve problems.

estimate and round
2.3 Identify one more than, one less than, 10 more than, and 10 less than a given
number.

multiply
2.4 Count by 2s, 5s, and 10s to 100.


Solving Equations
1.1 Write and solve number sentences from problem situations that express relationships involving addition and subtraction.
1.2 Understand the meaning of the symbols +, −, =.
1.3 Create problem situations that might lead to given number sentences involving addition and subtraction..



1.1 Sort objects and data by common attributes and describe the categories.
1.2 Represent and compare data (e.g., largest, smallest, most often, least often) by using
pictures, bar graphs, tally charts, and picture graphs.
Shapes
2.1 Describe, extend, and explain ways to get to a next element in simple repeating
patterns (e.g., rhythmic, numeric, color, and shape).



Charts, Data,
Function Tables and Graphs
1.1 Record numerical data in systematic ways, keeping track of what has been counted.
1.2 Represent and compare data (e.g., largest, smallest, most often, least often) by using
pictures, bar graphs, tally charts, and picture graphs.

Properties
2.0
Students sort objects and create and describe patterns by numbers, shapes, sizes, rhythms, or colors:
2.1 Describe, extend, and explain ways to get to a next element in simple repeating
patterns (e.g., rhythmic, numeric, color, and shape)..




1.1 Determine the approach, materials, and strategies to be used.
1.2 Use tools, such as manipulatives or sketches, to model problems.
2.0 Students solve problems and justify their reasoning:
2.1 Explain the reasoning used and justify the procedures selected.
2.2Make precise calculations and check the validity of the results from the context
of the problem.
3.0 Students note connections between one problem and another.
