TÍTOL: GEOMETRY: PERIMETER AND AREA

GRUP D’EXPERIMENTACIÓ PER AL PLURILINGÜISME

2

1. You will learn the difference between solid shapes and plane shapes.

2. You will observe and identify squares and rectangles all over our classroom.

3. You will learn what’s the difference between a rectangle and a

square.

4. You will learn the properties of plane shapes such as sides and corners.

5. You will learn that the point where two sides meet is called a corner.

6. You will learn to measure lengths widths.

7. You will draw squares and rectangles according to a measure given.

8. You will work in teams to measure perimeters and areas from

squares and rectangles in real life.

9. You will observe pictures/reality to identify squares and rectangles trying to deduce their real dimensions and decide which unit is better in each situation.

10.You have to use English as much as you can at all times.

Are you ready?????

Session 2 - Worksheet 2 Let’s measure perimeters

To do this task, you need a ruler, a table and a no tebook. 1.Using the ruler, measure the 4 sides of your tabl e. Write the numbers in the right place:

2.Calculate the perimeter of your table:

Remember : h + h + w + w = perimeter (cm)

3.Using the ruler, measure the 4 sides of your note book. Write the numbers in the right place:

4.Calculate the perimeter of your notebook:

Width = w = ...... cm

Width = w = ....... cm

Height = h = ....... cm

Height = h = ....... cm

Width = w = ...... cm

Width = w = ....... cm

Height = h = ....... cm

Height = h = ....... cm

Remember : h + h + w + w = perimeter (cm)

5. The perimeter is ............................... .......................................................... 6 – Calculate the perimeter of this square: A. 16 cm B. 20 cm C. 25 cm

5 cm 7– Calculate the perimeter of this rectangle:

A. 13 m B. 21 m C. 26 m

8 cm 5 cm

Homework – Your Bedroom 1. – Measure your bedroom. . How many meters does the length (long side) measu re? ---------- . How many meters does the width (short side) measu re? ---------- . Is your room a square? Yes, it is / No, it isn’t . . Is your room a rectangle? Yes, it is / No, it is n’t. 2. - Now, you can calculate the perimeter of your r oom (in case your room is a square, you must draw it here). a

a a a Perimeter = a + a + a + a = m The perimeter of my room is --------------- square meters 3. - Calculate the area of your room a

b Area= a x b= m2 The area of my room is -------------- square meters. . Is your room a square? Yes, it is / No, it i sn’t . Is your room a rectangle? Yes, it is / No, it isn’t

Session 5 - Worksheet 5 Group Project: A Room at School At school we want to renovate the floor and put dow n new tiles and a new baseboard.

TILES BASEBOARD

We have 8 equal size classrooms, a computer room, a music classroom, a support classroom, an English classroom, a staff ro om and the boys’ toilets and girls’ toilets. Each group is in charge of measuring one of these r ooms. Two students will be in charge of measuring and the third student has to note the measurements down. Your group has assigned the room: ............................................................................................................................. Tasks: 1. Your group has to show a drawing of the room wit h the measurements. 2. Your group has to calculate the area and the pe rimeter of your assigned room. 3. Your group has to say how many square meters of tiles are needed and how many meters of baseboard are needed. 4. Finally, your group has to share the information with the rest of the class by a poster.
