### Target 1​

###### Lesson Type:

New

Measurment

:

Techniques and Formulas

Solve problems involving perimeter.

###### 1:

Understand that perimeter is the distance around a figure.

###### 2:

Understand that the missing side can be found using the perimeter and the known sides.

4th

###### Vocabulary:

Perimeter, Missing side, Distance around, P=2L+2W

Activities:

1. Students showed their understanding of perimeter by solving teacher created shapes with cubes. They learned and understood that they needed to measure around the whole shape and every cube was one unit.

2. Students were given one side of the perimeter and needed to solve the other sides based on what they know about if one side is a certain number, the other side is the same.

## Absent Students:

### Target 2

:

###### 1:

Recognize area as a measurement of 2D shapes.

###### 2:

Recognize that area is measured in squared units (i.e., cm2), depicting that the measurement has both height and width.

###### 3:

Use the formula for finding the area of rectangular shapes (A = base x height).

4th

###### Vocabulary:

Area, Units squared, Centimeters squared, Length, Width, Base, Height, Rectangular

Activities:

1. Students were introduced to what area is and how it is found. We talked about 2D shapes and also real life examples of area.

2. After doing a few examples using cubes on an area board, students needed to show me a few of their own examples. They had to identify the formula and solve it.

3. Once they were finished with their examples and there was a clear understanding, they started to build a house on 1cm grid paper. They were given specifications of either the area or perimeter. From that information, they needed to find the one that was blank.

### Target 3

:

###### 1:

Identify the correct arithmetic processes based on the information presented in word problems.

###### 2:

Find the key words in word problems that indicate the correct arithmetic process to use: Addition: add, altogether, both, combined, in all, plus, sum, total; Subtraction: difference, fewer, how many/much more, left, less, minus, remains; Multiplication: times, product, each, twice; and Division: how many in each, divided by, quotient, goes into, split evenly.

###### 3:

Find and use the needed information in a word problem to solve.

4th

###### Vocabulary:

CUBES, Multi-step, Arithmetic process

Activities:

1. Students reviewed the meaning of the acronym "CUBES." After reviewing the acronym, students went around the room answering multi-step Christmas type task card word problems. It involved using addition, subtraction, multiplication and or division. There were money problems and using whole number problems. Students shared their strategies, while addressing the "CUBES" method.
