M th L sson:
Addition & Subtraction
L rning Go ls
● We are learning to add and subtract whole numbers.
● We are learning to add and subtract decimal numbers.
● We are learning to solve word problems involving 1-2
operations.

Multi-Digit A ition

ollowing qu stion:
Hundreds Tens Ones

● Can anyone remind me what numbers we would start with adding together?
Multi-Digit A ition

● We always start adding from the right side (ones column) and
move to the left
● If the sum is greater than 9, we need to carry over to the next
column
● Since the sum from the tens column is greater than 9 (5+6), we
need to carry the ten over to the hundreds column

● Would we start with the ones column like we did for addition?
Multi-Digit Su tr tion

● We always start by subtracting from the right side (ones


column) and move to the left
● Subtracting multi-digit numbers works the same way as adding
multi-digit numbers, except we are borrowing numbers
● Since we cannot subtract 6 from 4, we need to borrow a ten
from the tens column. We can now subtract 6 from 14.

What are some common words that are found in subtraction word
problems?

● “Difference”
● “Change”

decimal is the whole
number
● The part after the decimal
6 6 2 1 2
is a value less than one

Example: 662.12

● We will add and subtract decimal numbers the same way that we did
for whole numbers!
● However, we need to remember to insert the decimal into our
answer.
● Let’s solve the following question:

46.4
+ 32.5
78.9

On your whiteboard, solve the following problem:

● Simon and his brother wanted to see who could

times?
