Sometimes nothing is added and nothing is taken away.
Step 1: Let's Learn
Read it, or press Listen and follow the words.
Two groups, side by side
You just have two groups. The question is how many more one has.
Match them up
Pair them one to one. The ones with no partner are the difference.
Difference is how many more one group has than the other.
Matching answers it without counting
Pair them one to one. Whatever is left over is the difference, and you never had to count either group.
More and fewer are one question
If there are three more red than blue, there are three fewer blue than red. The same gap, described from either side.
Step 2: Try It Yourself
Line them up and count the ones with no partner.
Ana
Leo
8 is greater than 5.
Step 3: Watch an Example
One step at a time.
Watch Ana Match
Ana has 8 stickers. Leo has 5.
- Step 1
She pairs one of hers with one of his, again and again.
Step 4: Your Turn
Practice makes it stick.
