Add units of length, involving conversion of units in; a. Millimeter b. Meter and millimeter c. Centimeter and millimeterActivities : Demonstrate additions of length in vertical form and convert the answers using concepts of fractions and decimals.Moral Values : Cooperative and CarefulThinking Skills : Comparing and ReasoningTeaching Aids : Games Software, paper strips, ruler, Microsoft Power Point slide shows
2. 2. TEKNOLOGI MAKLUMAT DALAM PENDIDIKAN (HBEF 2303) ZAMATUN NASRAH BINTI MARWAN (770218-01-5450)Teaching and Learning Activities PHASE CONTENT TEACHING & LEARNING NOTES ACTIVITIES Introduction Games (Sharemath) Teacher shows a sharemath games Resources: using CD. Sharemath games Teacher asks pupils to count and software answer the questions. Teacher: I want you to answer the Mod: questions. Tutorial Teacher introduces the lesson. Teacher: Today, we are going to learn addition of lengths. Step 1 Introducing addition of Teacher uses Microsoft Power Point Resources: lengths involving units; to introduce addition of lengths in Microsoft a) Millimeter vertical form. Power b) Meter and Point, grid centimeter Teacher shows two ribbons with paper, c) Centimeter and different measurements. ribbons and millimeter Teacher: I want you to measure ruler in vertical form without these two ribbons. Write it on the conversion. paper. Moral values: Careful and cooperative
3. 3. TEKNOLOGI MAKLUMAT DALAM PENDIDIKAN (HBEF 2303) ZAMATUN NASRAH BINTI MARWAN (770218-01-5450)PHASE CONTENT TEACHING & LEARNING NOTES ACTIVITIES Teacher guides pupils to write the Mod: number sentence and find the total Tutorial length of the ribbons. Teacher: Then, you count the total length of these ribbons. Firstly, you’ve to write in number sentence. e.g: 67 mm + 87 mm = _____mm Teacher explains the concept of addition in vertical form without conversion. Teacher: you can count this question in vertical form. Teacher proceeds with other questions. Teacher: Now, I want you to look at this example. Try to solve this question in vertical form. e.g: 56 cm + 43 cm =_____ 56 cm + 43 cm __99 cm

TEKNOLOGI MAKLUMAT DALAM PENDIDIKAN (HBEF 2303) ZAMATUN NASRAH BINTI MARWAN (770218-01-5450)PHASE CONTENT TEACHING & LEARNING NOTES ACTIVITIES Teacher guides pupils to convert 99 Mod: cm to meter using concepts of Tutorial fractions and decimals. Teacher: Now, I want to show you, how to convert this measurement to meter using fractions and decimals. Teacher asks pupils: How many centimeters are there in 1 meter? (100 cm) Teacher: Now, you know that 1 meter is equal to 100 cm. Alright, I give you this grid paper with 100 boxes.
5. 5. TEKNOLOGI MAKLUMAT DALAM PENDIDIKAN (HBEF 2303) ZAMATUN NASRAH BINTI MARWAN (770218-01-5450)PHASE CONTENT TEACHING & LEARNING NOTES ACTIVITIES Mod: Teacher: Alright, now I want you to Tutorial shade 99 boxes from these 100 and boxes. aplication Teacher: Now, 99 cm are out of 100 cm in fraction is From here, we know that is equal to 0.99. 99 cm = 0.99 cm Pupils also can check how to convert units of length from this resource: http://www.mathplayground.com/ho wto_metric.html
6. 6. TEKNOLOGI MAKLUMAT DALAM PENDIDIKAN (HBEF 2303) ZAMATUN NASRAH BINTI MARWAN (770218-01-5450)PHASE CONTENT TEACHING & LEARNING ACTIVITIES NOTESStep 2 Introducing addition Teacher gives questions: compound units. e.g: Resources: e.g: meter and 7 m 60 cm + 3 m 45 cm = ______m Microsoft centimeter and Power Point convert the answer Teacher asks pupils to write the to meters. questions in vertical form. Teacher: Please write this number sentence in vertical form. Teacher guides pupils to add starting with cm and regroup when necessary. Teacher: Start adding with cm. If the answer is more than 100 cm then, we must do the regroup. 7 m 60 cm + 3 m 45 cm 10 m 105 cm Add 60 cm and 45 cm. The total is 10 m 105 cm. 105 cm = 100 cm + 5 cm Write 5 cm, regroup 100 cm to 1 m. Add 1 m + 10 m. The total is 11 m. The answer is 11 m 5 cm.
7. 7. TEKNOLOGI MAKLUMAT DALAM PENDIDIKAN (HBEF 2303) ZAMATUN NASRAH BINTI MARWAN (770218-01-5450)PHASE CONTENT TEACHING & LEARNING ACTIVITIES NOTES Partition 11 m 5 cm into 11 m + 5 cm, and convert 5 cm to meter using concept of fractions and decimals. 11 m 5 cm = 11 m + 5 cm = 11 m + 0.05 m = 11.05 mStep 3 Work It Out! Teacher asks pupils to take 2 paper strips with different colour and measure separately on their desk. Teacher: Please take this paper strips. Each of you must have two paper strips with different measurements. Teacher asks pupils to measure the first paper strip then, the second paper strip. Teacher: Take out your ruler and measure the first paper strip followed by the second paper strip. Teacher asks the pupils again to write the measurements on the paper strips. Teacher: You must write the measurement that you get on the paper strips.

TEKNOLOGI MAKLUMAT DALAM PENDIDIKAN (HBEF 2303) ZAMATUN NASRAH BINTI MARWAN (770218-01-5450)PHASE CONTENT TEACHING & LEARNING ACTIVITIES NOTES e.g: Mod: Tutorial 90 mm 65 mm Teacher asks pupils to joint these 2 paper strips closely and asks the pupils to measure the length of the paper strips together in order to find the total length. Teacher: Now, joint your paper strips together. Then, you measure the length of the paper strips to find the total length. Is it same if we just add this length in vertical form. 65 mm 90 mm 155 mm Teacher proceeds with addition of units of length in cm and convert the answer to meters using long division. Teacher: I want you to convert this length from cm to meters using division.
