Direct Instruction

• Show students a few examples of decimal numbers and have them identify the place value of each digit.
• Ask students to identify the largest and smallest digits in each number.
• Explain that when we add or subtract decimal numbers, we need to make sure that the numbers have the same place value.
• For example, when adding 00.56 and 0.23, we need to make sure that the 5s are the same place value and the 0s are the same place value.
• Show students how to use place value to add and subtract decimal numbers.
• For example, when adding 00.56 and 0.23, we need to add the 6s and the 3s first, then add the 0s.
