Add, Subtract & Compare
Question 1.
Fill in the missing numbers on the addition tables. Some of the numbers have already been filled in for you.
a.
Answer:
Firstly, identify the row and column to which you want to add then follow up with the respective row and column and find the sum of them. Let us say the first row begins with 2 and in the first column we have 1 adding these we get 2+1 = 3. Likewise adding the next numbers we have 3+1 = 4. Repeat the process until all the addition table is filled based on the strategy listed.
b.
Answer:
Firstly, identify the row and column to which you want to add then follow up with the respective row and column and find the sum of them. Let us say the first row begins with 2 and in the first column we have 1 adding these we get 3+3 = 6. Likewise adding the next numbers we have 4+3 = 7. Repeat the process until all the addition table is filled based on the strategy listed.

Place Value Showdown
Note to Families
This game uses drawings to stand for numbers. The little square unit stands for 1, the strip of ten stands for 10, and the mat of one hundred stands for 100. If you have a collection of 2 mats, 3 strips, and 4 units, you’re looking at 234. Place Value Showdown will help your child become more comfortable reading, understanding, and comparing 2- and 3-digit numbers.
