Reviewing the previous lesson or presenting the new lesson Have a review on non-standard units, and the concept of volume and a solid. Ask pupils to show examples of solid figures like boxes, alphabet blocks, etc. 76 B. Establishing a purpose for the lesson Show 3 empty boxes of the same size. C. Presenting examples/ instances of the view lesson Present the story to the class. Show solid items like marbles, match boxes, corns: Ask: Do you think these boxes will be filled with the same number of marbles, corns and match boxes? Why? Accept guessed answers then lead to the new lesson. (volume of solid) Roy wanted to find out which box, A or B, has the greater volume. He filled box A with marbles. Then he transferred the marbles to box B. After box B was full, there were still some marbles in box A. BOX A. BOX B 300 marbles filled box A filled with 200 marbles Box A 30 remaining marbles in box A D. Discussing new concepts and practicing new skills #1 Ask: -Which box has the greater volume? Let them compare the contents by counting the 77 number of marbles and by comparing the sizes of the boxes. -Why the boxes do not have the same number of objects? -Why there are gaps or empty spaces within the boxes? Explain the meaning of volume and non-standard units. Explain the comparison when using the smaller and bigger non-standard units needed to fill a container or box. Remind the pupils that non-standard units do not give a consistent and accurate measurement of the volume of a container. E. Discussing new concepts and practicing new skills #2 Group Activity: Divide the class into four groups. Distribute the box to each group. Let the group fill the box with the materials given to them to find the volume of the box. GI- using marbles GII- using beans GIII- using match boxes GIV- using corns Let them count the number of objects in filling the box. Let any member of the group report the result of their activity and discuss how to find the volume using nonstandard units. (The number of objects contained in the box is the volume of the box.) F. Developing Mastery (Leads to Formative Assessment 3) Find the actual number of balls that will fill each box of different sizes. 78 G. Finding practical application of concepts and skills in daily learning Let the pupils do items 1 and 2 under. Apply your skills on pp. 228 of LM. Read and answer each problem: 1. Two containers were filled with marbles of the same material and size. Container A had 200 marbles. Container B had 250 marbles. In what way does the volume of container A compare with the volume of container B? Expected Answer: Container B has a greater volume than container A Container B has 50 more marbles than container A Container B is bigger that container A 1.

Reviewing the previous lesson or presenting the new lesson Have a review on the volume of solid figures using non-standard units, and concept of solid dimensions. Ask pupils to give examples of non-standard units of measure. Showing solid figures like boxes and give their dimensions. How do you find the volume of solid using the non-standard units? Give examples. How many marbles filled this box? 83 Box A Box B 42 Marbles What is then the volume of Box A? How many balls contained in Box B? 20 balls B. Establishing a purpose for the lesson C. Presenting examples/ instances of the view lesson What is the volume of Box B? Let the pupils remember that the number of objects that filled in the box is the volume of the box. Show a Rubik’s cube. Ask if the pupils are familiar with this toy. What is challenging about this toy? What value needed in yourself if you play this toy? How many small cube found is this Rubik’s cube? Let the pupils count. What are the dimensions of this Rubik’s cube? Present this situation to the class. Let the pupils read and understand the situation. Carlo has a transparent rectangular container, measuring 10 cm by 4 cm by 3 cm. What is the volume? h-4cm w-3cm L-10cm 1. Who has a transparent rectangular container? Answer: Carlo 2. What is the length? Height? Width? Answer: L=10 cm W= 3cm H= 3 cm 3. What does the problem asked for? Finding the volume of a rectangular container 84 4. How will you solve the volume of rectangular prism? D. Discussing new concepts and practicing new skills #1 - Answer: By multiplying the length ,width and height Show to the class an example of rectangular prism. Show them the length, the width and the height. Emphasize that the rectangular prism is 3dimensional figure that has six faces that are rectangles, twelve edges and eight vertices. Vertex is the corner of a shape, while edge is a segment where two faces of a prism meet. Discuss the presentation under Explore and Discover on page 229, LM. Show the difference among cubic unit, 2 cubic units, and 4 cubic units as an example that will lead to standard units for measuring volume. Cubic centimeter – cm3/cubic meter – m3 2 cubic units 4 cubic units If 1 cubic unit is equal to 1 cubic cm, then the volume is 4 cm3. A cubic centimeter (cm3) is a standard unit for measuring volume. A cubic meter (m3) is another one. The figure at the left contains 27 cubes. Its volume is 27 cubic cm or 27 cm3. E.
