1. Motivation:

Teacher Activities Student Activities

Review the addition and subtraction of dissimilar fractions.

1. 7 5/8 + 5 1/6 =2. 9 1/6 + 8 2/9 =3. 6 3/8 - 4 2/6 =4. 4 2/6 - 2 1/5 =

1. 7 15/24 + 5 4/24 = 12 19/242. 9 3/18 + 8 4/18 = 17 7/183. 6 9/24 - 4 6/24 = 2 3/24 / 2 1/84. 4 10/30 - 2 6/30 = 2 4/30 / 2 2/15

Opening Activity

Read page 169 of your workbook.

“Pinakbet”Ingredients:

¾ cup pork liempo, cut into strips¼ cup strained bagoong isda1 ½ cups rice washing1 pc. Medium tomato, sliced½ tbsp. ginger strips2 squares tokwa, fried and cut into cubes¾ cup squash chunks6pcs. okra, sliced4 medium eggplants, sliced1 large ampalaya, seeds removed and sliced1 small bunch sitaw, cut into small pieces

Procedure:1. Sauté pork until light brown. Add bagoong isda, rice washing, tomato, onions, and ginger. Bring to boil.2. Simmer for a few minutes. Add the rest of the ingredients. Cover and simmer for 15mins.or until cooked.

Makes 8 servings.

Modify the amount of ingredients to serve 3 ½ times the number of servings in the original recipe.

Reading carefully and silently.

Developmental Activity

1. How many servings will the modified recipe serve?

2. How many pieces of okra are needed to make 3 ½ times the recipe?

3. How many cups of pork are needed for 3 ½ times the recipe?

4. How do you changed mixed numbers to improper fractions?

5. How do you multiply fractions?

8 servings multiply by 3 ½ is equals to 56/2. Reduce to lowest term equals 28.

6pcs. okra multiply by 3 ½ is equals to 42/2. Reduce to lowest term equals 21.

¾ cups pork multiply by 3 ½ is equals to 21/8 or 2 and 5/8.

Multiply the whole number by the denominator. Then add the product to the numerator.

Multiply the numerators to get the numerator of the product. Multiply the denominators to get the denominator of the product.

3. Generalization:

To change mixed numbers to improper fractions, multiply the whole number by the denominator. Then add the product to the numerator. The result is the new numerator over the given denominator.

To multiply fractions, multiply the numerators to get the numerator of the product. Multiply the denominators to get the denominator of the product. Express the product in lowest terms.

If the factor is a mixed number, change the mixed fraction to improper fraction first before finding the product.

4. Application:

Teacher Activities Student Activities

Change mixed fraction to an improper fraction.1. 7 ¾ =2. 12 ½ =

Find the product.1. ¾ x ½ =2. 2/3 x 1/8 =

1. 31/42. 23/2

1. 3/82. 2/24 reduced to 1/12

IV. EVALUATION

A. Change each to an improper fraction.

1. 1 4/62. 3 3/63. 5 4/84. 7 3/75. 9 5/6

B. Find the product.

1. 1/2 x 3/42. 8 1/3 x 6/73. 22 x 3/84. 2 2/5 x 1 1/65. 3/4 x 5/6 x 4/15
