Numeration-Problem Solving Read the problem more than once Identify the important and junk information Decide which mathematical operation needed to solve the problem Organize your data Apply the operation to the data
Numeration I am a number less than 50. When divided by 5, by remainder is 4. The sum of my digits is 11. What number am I?
Numeration Identify important information Number is less than 50 When divided by 5, the remainder is 4 The sum of the digits is 11
Numeration Which operation is needed to solve the problem? Division Addition (Sum) Logical Thinking
Numeration Organize your data My number is less than 50 The number must be between 1-49 The number must be a 2-digit number in order to get a sum of 11 Therefore 1-9 is eliminated The numbers must be between 10-49
Numeration Which two numbers between 10 and 49 have a sum of 11? Use Guess and Check Use the working backwards strategy to solve the problem Once you have found numbers whose sum is 11, divide it by 5 to check for a remainder of 4
Numeration Using guess and check and the working backwards strategy you found that the number is 29 2 + 9 = 11 29 divided by 5 = 5 remainder 4 Did you solve the problem?
