Here is the printable Subtraction Flashcards
You can use this activity in teaching subtraction of one 2-digit number from another 2-digit number without regrouping.
First, you need to print out the flashcards and cut each one of them.
In a big class, you can provide a set of these flashcards for each group you have, or your students can do it by pairs or fours. It really depends on you.
After you distribute a set of flashcards to each team or student, have them find the difference of each subtraction sentence then pair the number sentences with the same answer.
The winner of this game is the first team or student who pairs up all of the subtraction sentences correctly.
Addition and subtraction are two related operations; addition is the inverse operation of subtraction, and subtraction is the inverse of addition.
Take a look at these number sentences:
8 + 2 = 10
10 – 2 = 8
Here are the free worksheets that your children can use in practicing their skills on finding the missing addends and in writing subtraction sentences based on addition sentences. Enjoy!

Nouns can be classified into mass nouns and count nouns.
Count nouns can be counted like fish, pen, bag, glasses, chairs, people, and pets.
Mass nouns cannot be counted like water, sand, oil, and ink.
Tell if each word is a mass noun or a count noun.
Items 1, 2, and 5 are count nouns because we can count them using ordinal numbers. Items 3 and 4 are mass nouns because we can’t really count these things one by one. We need to use phrases like a cup of coffee and a bottle of glue to describe their amount.
Here is an exercise for your to practice more in identifying mass and count nouns.
