Grade 3 Maths (IMO) : Addition strategies
Listing down some methods to simplyfy addition.
- Doubles (such as 6 + 6)
- Near doubles: Try adding a double and the remainder. Solve 7 + 6, (6 + 6+ 1) or (7 + 7 – 1).
- Making a ten or a multiple of 10: To add 7 + 6, I can take 3 from the 6 and put it with the 7 to make 10 and 3. This holds good even with multiples of 10 like 20, 30 40, etc
- 1 more, 1 less: Show problems such as: 8 + 1, 51 + 1, and 6 – 1, 22-1
- Place value Decomposition: 35 + 22 can be decomposed into tens and ones 30+20 added to 5+2. Or 35 – 22 can be decomposed to 30-20 plus 5-2.

Taming the tables – Tips to introduce multiplication
Some tips and tricks to start multiplication which will help you in knowing your times tables. I followed this approach with my daughter (she is in grade 1 rt now) and am very happy with the results. She does not have any apprehensions of which table is asked and does a quick mental maths if she does not know the answer.
Tips to approach the concept of multiplication :
I explained these concepts using lego pieces . You can use anything small and handy.
- Now that the kids know 2 digit addition the best approach to start multiplication is by asking them to do repeated addition. Ask them to count the objects in groups of 2 then 3 and so on.
- Once they are thorough with repeated addition you can ask them to do skip counting.
- Ask them to divide the total number of objects into equal groups.
- Arrange the total number of objects in an array of row and column.
Below is a figure to illustrate how multiplication can be introduced to kids.

Step 1 : Look at the changes / similarities between each diagram
Step 2 : Look for a pattern in the changes
Step 3 : Do the different changes one at a time.
