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?
