Expectations

Students are expected to:

*have all materials needed for class (math book, pencil, homework, and math journal)

*participate in class

*be an active listener (hands and feet quiet, and looking at the speaker)

*raise hand if they have a question or comment

*practice math facts at home

*always do their best work

## i can statement

By the end of second grade, the student should be able to say:

__Operations and Algebraic Thinking:__*I can use strategies to solve addition word problems (within 100).

* I can use strategies to solve subtraction word problems (within 100).

* I know my addition facts from memory.

*I know my subtraction facts from memory.

*I can group objects to tell if a number is odd or even.

*I can write a number sentence to show how adding two of the same number will equal an even number.

*I can use addition to help me figure out how many objects are in an array.

*I can write a number sentence to show the total number of objects are in an array.

__Number and Operations in Base Ten:__

* I can understand and use hundreds, tens and ones.

* I can show that I understand that a bundle of ten "tens" is called a "hundred".

* I can show that I understand the numbers I use when I count by hundreds, have a certain number of hundreds, 0 tens and 0 ones.

* I can count to 1,000 by 1s, 5s, 10s and 100s.

*I can read and write numbers to 1,000 in different ways. (numerals, word names, expanded form)

* I can compare three digit numbers using <, =, and > because I understand hundreds, tens and ones.

* I can add two-digit numbers.

* I can subtract two digit numbers.

*I can add up to four 2- digit numbers.

*I can use strategies to add numbers within 1000 and know when to regroup.

* I can use strategies to subtract numbers within 1000 and know when to borrow.

* I can add and subtract 10 or 100 to any number from 100 to 900 in my head.

* I can explain why adding and subtracting strategies work using what I know about place value.

__Measurement and Data__*I can use different tools to measure objects.

* I can use two different units to measure the same object and tell how the measurements compare.

* I can estimate the lengths of objects using inches, feet, centimeters and meters.

*I can tell the difference in the lengths of two different objects.

*I can use addition and subtraction to solve measurement problems.

* I can make and use a number line.

*I can tell time to five minutes.

* I can use a.m. and p.m. in the right ways.

*I can count money to help me solve word problems.

* I can make a table to organize information about measurement.

* I can show measurements with a line plot.

* I can draw a picture graph to share number information.

* I can draw a bar graph to share number information.

* I can solve problems using information from a bar graph.

**:**

__Geometry__*I can name and draw shapes. (I know triangles, quadrilaterals, pentagons, hexagons and cubes.)

* I can find the area of a rectangle by breaking it into equal sized squares.

* I can divide shapes into equal parts and describe the parts with words like halves or thirds.

* I can understand that equal parts of a shape may look different depending on how I divide the shape.

## assignments/homework

Students will have homework on Monday - Thursday. The homework is usually workbook page(s) or a worksheet. The actual assignment will be written in their planners each night.

In addition to the nightly homework, students are expected to practice math facts at home.
