Compare two at a time. Find the shortest first.
Step 1: Let's Learn
Read it, or press Listen and follow the words.
Then compare the two that are left.
Do it two at a time
Find the shortest, put it down, then the shortest of what is left. Three-way comparison is just easy two-way ones in a row.
The middle one is both
It is longer than one and shorter than another at the same time. Longer always needs something to be longer than.
Step 2: Try It Yourself
Tap and try it out.
Step 3: Watch an Example
One step at a time.
Watch Mia Put Them in Order
Mia has a 4-cube pencil, a 7-cube crayon and a 9-cube ruler.
- Step 1
She finds the shortest first: the pencil at 4.
Step 4: Your Turn
Practice makes it stick.
