__Organizing, Representing, and Interpreting Data and Time to the Half-Hour__In this unit, students tell and write time to the half-hour using analog and digital clocks. They organize and represent data in up to three categories. They will ask and answer questions about the data.

**Common Core Focus:**

Common Core Focus:

* Tell and write time to the half hour using analog and digital clocks.

* Organize data and represent data with up to three categories.

* Ask questions about total number of data points and tell how many more or less there are in one category than another.

__Strategically Solve Addition and Subtraction Problems within 20__

In this unit, students students use addition and subtraction within 20 to solve word problems involving unknowns in all positions. They will solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20. Students will demonstrate fluency for addition and subtraction within 20.

Addition and Subtraction within 10

The children have been working hard learning strategies to help them solve addition and subtraction problems within 10. By the end of first grade, children should be able solve all problems within 10 in three seconds a problem. In order to help the children learn how to do this, the problems are broken down in strategies. You may have heard your child use the words: "ten friend" , "double", or "counting on". Below is a description of each strategy the children are learning:

Count on 1, 2, 3:

When adding two numbers, put the larger number in your head and count on 1, 2, or 3. You may have to change the order of the addends to do this. 6+3=(6... 7, 8, 9), 2+7=(7...8,9)

Count Back 1, 2, 3:

Put the whole in your head and count back. 9-2= (9...8,7)

Count On "Think Addition" :

When subtracting and the numbers are close start with the small number and count on to the large number to get the difference.. 9-7= (7...8,9 your answer is 2)

Doubles:

Adding a number to itself. 2+2=, 4+4=, also knowing if 4+4=8, then 8-4=4.

Near Doubles or Doubles +1:

When adding two numbers that are one apart (or number neighbors) double the small number and add one to the answer. 4+3=, double the 3 and add 1 to the answer. 3+3=6, so 4+3=7.

Ten Friends:

Two numbers when added together equal 10. 4+6=10, 8+2=10

Also knowing when 10 is the whole and you take away a part, the missing part is the ten friend. 10-7=3.

Below are addition and subtraction strategy flashcards. Some strategies will be introduced as we move on in the year. Feel free to copy at your convenience!
