### Target 1

###### Lesson Type:

New

Number Operation

:

Computation

Subtract within 1,000 (regrouping limited to only one place-value).

###### Supporting targets:

###### 1:

Understand why the standard algorithm for subtraction is based on place-value.

###### 2:

Understand that when subtracting a multi-digit number, each place-value is being subtracted individually to create the new number (ones are subtracted from ones, tens are subtracted from tens, etc.)

###### 3:

Understand that when adding a multi-digit number, to solve start in the lowest place-value and go left.

###### 4:

Understand how to regroup based on place-value understandings (i.e., ten ones can be composed into one ten – ten tens can be composed into one hundred).

###### 5:

###### Grade:

3rd

###### Vocabulary:

Subtract, Regroup, Trade, Hundreds, Tens, Ones

Activities:

Students solved two or three digit subtraction problems involving regrouping.

- Students used place value and base ten blocks to build the numbers and act out subtraction.
- Students used regrouping when necessary, trading 1 ten for 10 ones or 1 hundred for 10 tens.

###### Geometry

###### Coordinates

###### Use coordinates to find a location on a grid.

:

###### Supporting targets:

###### 1:

Identify the x- and y-axis on a coordinate plane.

###### 2:

Become familiar with quadrant I of the coordinate plane and that all coordinate pairs will have positive numbers in this quadrant.

###### 3:

Become familiar with quadrant II of the coordinate plane and that the first number can be either positive or negative.

###### 4:

Understand that the first number in a coordinate pair indicates placement on the x-axis and the second indicates placement on the y-axis.

###### 5:

###### Grade:

2nd

###### Vocabulary:

Coordinate, X-Axis, Y-Axis, Negative, Positive

Activities:

Students understood that the first number in a coordinate referred to the x-axis and the second number referred to the y-axis.

- Students identified the location of different coordinates in both quadrant I and II.
- Students found the intersecting points on the coordinate grid and placed sea animals at the given coordinates.
- Students placed stickers at different locations on a coordinate grid and recorded their coordinates.
