Put one next to one. The row with some left over has more.
Step 1: Let's Learn
Read it, or press Listen and follow the words.
Match them up
One flower goes with one flower. Another goes with another. The top row still has one left over. So the top row has more.
More and fewer
More is the bigger group. Fewer is the smaller one.
Step 2: Try It Yourself
Tap and try it out.
This row
That row
3 is less than 5.
Top row
Bottom row
How many in all
Step 3: In Real Life
Sharing grapes
You have grapes. Your friend has grapes. Line them up side by side. The longer line has more.
Step 4: Watch an Example
One step at a time.

- Step 1
He puts one car next to one block.
Step 5: Your Turn
Practice makes it stick.

Question 1 of 1
Which is more, 5 or 3?
What You Learned
- Match one to one to compare.
- The row that keeps going has more.
For the grown-up
Matching one to one tells you which group is bigger without counting either, which works for numbers far beyond what the child can yet count.
A spread-out row looks like more and is not. Spreading things out adds space, not objects. This is the classic conservation error and children hold it firmly, so showing it beats explaining it.
Line them up in pairs and the spreading cannot mislead. If they still say the longer row has more, push the rows together in front of them and ask again.
