# What should I Learn?

## Operations and Algebraic Thinking

How to solve addition and subtraction word problems in situations of adding to, taking from, putting together, taking apart, and comparing (e.g., a taking from situation would be: “Five apples were on the table. I ate some apples. Then there were three apples. How many apples did I eat?”).

How to add fluently with a sum of 10 or less, and accurately subtract from a number 10 or less (e.g., 2 + 5, 7 – 5).

Understand the relationship between addition and subtraction.

## Number and Operations in Base Ten

How to understand what the digits mean in two-digit numbers (place value).

How to use my understanding of place value and properties of operations to add and subtract (e.g., 38 + 5, 29 + 20, 64 + 27, 80 – 50).

How to understand and identify the value of pennies, nickels and dimes.

## Measurement and Data

How to measure lengths of objects by using a shorter object as a unit of length.

How to tell and write time.

## Geometry

How to make composite shapes by joining shapes together, and dividing circles and rectangles into halves or fourths.

## Operations and Algebraic Thinking

Solve challenging addition and subtraction word problems with one or two steps (e.g., a “one-step” problem would be: “Lucy has 23 fewer apples than Julie. Julie has 47 apples. How many apples does Lucy have?”).

Fluently add with a sum of 20 or less (e.g., 11 + 8); fluently subtract from a number 20 or less (e.g., 16 – 9); and know all sums of one-digit numbers from memory by the end of the year.

Work with equal groups of objects to gain foundations for multiplication.

## Number and Operations in Base Ten

Understand what the digits mean in three-digit numbers (place value).

Use an understanding of place value to add and subtract three-digit numbers (e.g., 811 – 367); add and subtract two-digit numbers fluently (e.g., 77 – 28).

## Measurement and Data

Solve addition and subtraction word problems involving length (e.g., “The pen is 2 cm longer than the pencil. If the pencil is 7 cm long, how long is the pen?”).

Tell time.

Count money.

## Geometry

Build, draw, and analyze 2-D and 3-D shapes to develop foundations for area, volume, and geometry in later grades

**.**Divide shapes into equal shares to build the foundations for fractions in later grades.
