How did the children like the activities?

*The worksheets were a great guide for them because they kept them focused, and the amount of , "What do I do?" questions were very minimal. They seemed comfortable referring back to the worksheets for definitions and examples. I also noticed there was a lot less hand-raising.*

How did you like using Math Mammoth materials?

*It definitely made my job easier, because I did not have to continue going back to each group to explain what are or perimeter were. The definition was in front of them along with examples.*

How many class periods did you use them?

*It took us two 45-minute periods to complete all the activities. The students were so engaged they did not want to quit.*

Did you use both English and Spanish, or only Spanish worksheets?

*I only used the Spanish versions, but I plan on assigning the English for homework when we return in January.*

Did you give them any homework?

*They were able to keep their booklets in their math folder in order to refer to them in the future. They will usually go back and complete any unfinished assignments.*

LESSON PLANS & PICTURES

AREA

**Area and Perimeter Activities**

Ms. Pineda, 3rd Grade Bilingual Teacher

**Objective:**Measure the area of geometric shapes using square units.

**Materials:**Comenzando con área worksheet (a lesson from Mamut Matemáticas Geometría inicial),, attribute blocks, ¼ - ½ inch graphing paper, pencil, mini booklet made from manila paper, markers or crayons.

**Procedures:**

- Use the worksheet to discuss how area is calculated.
- Trace a shape using your pencil.
- Count the whole squares by writing the numbers.
- Combine two halves to make a whole square.
- If one of your shapes crosses four squares, combine them to make a whole.
- Once you have calculated the area of each shape. You may color it and glue it in your mini booklet.

Area = 4 + ½ + ½ = 5

PERIMETER

**Objective:**Measure the perimeter of geometric shapes in inches.

**Materials:**Perímetro worksheet (a lesson from Mamut Matemáticas Geometría inicial), attribute blocks, pencil, ruler, mini booklet made from manila paper, markers, and crayons.

**Procedures:**

- Use the worksheet to discuss how perimeter is calculated.
- Trace a shape on your booklet using your pencil.
- Measure each side of the shape in inches.
- Add the lengths to find the perimeter of each shape.
- Combine two halves (½ + ½ = 1)to make a whole inch.
- Trace the edges of each shape with a marker and color the area with a crayon.

Perímetro = 2 + 2 + 1 + 1 + ½ + ½ = 7
