What are the steps in solving a problem?

Problem 1 Leo bought 4 T-shirts and 2 pairs of pants for Php3000. If the T-shirts cost Php300 each, find the cost of each pair of pants.

Leo bought 4 T-shirts and 2 pairs of pants for Php3000 Leo bought 4 T-shirts and 2 pairs of pants for Php3000. If the T-shirts cost Php300 each, find the cost of each pair of pants. Problem 1 Php300 Php1200 Php3000 ? Php1800 ? Php900

Leo bought 4 T-shirts and 2 pairs of pants for Php3000 Leo bought 4 T-shirts and 2 pairs of pants for Php3000. If the T-shirts cost Php300 each, find the cost of each pair of pants. Understand a. What is asked? -the cost of each pair of pants b. What are given? -4 T-shirts and 2 pants for Php3000;Php300 each T-shirt 2. Plan a. What operation/s to use? -multiplication, subtraction and division Activities

Leo bought 4 T-shirts and 2 pairs of pants for Php3000 Leo bought 4 T-shirts and 2 pairs of pants for Php3000. If the T-shirts cost Php300 each, find the cost of each pair of pants. b. What is the number sentence? Let N=one pair of pants [Php3000-(4 x Php300)] 2 = N 3. Solve [Php3000-(4 x Php300)] 2 = (Php3000-Php1200) 2 = Php1800 2 = Php900 2 Activities 4.Check and Look Back So, each pair of pants costs Php900.

Problem 2 A farmer has some ducks and goats in his farm. A visitor counted 14 heads and 40 legs for those animals. How many ducks and goats are there in the farm? Activities

Group Activity Anne’s grades in Math for the 1st three quarters are 92, 86, and 88. What grade must she get in the fourth quarter to get an average of 90? Activities

Group Activity Anne’s grades in Math for the 1st three quarters are 92, 86, and 88. What grade must she get in the fourth quarter to get an average of 90? (92 + 86 + 88 + N) 4 = 90 92 + 86 + 88 + 94=360 Activities 360 4=90 N= 94

The steps in solving routine problems are: Understand-Know what is asked, what are given Plan-Know the operation, write the number sentence Solve-Perform the operation. Write the correct units/label your answer Check and look back-Review and check your answers. Write the complete answer. Activities
