The big ideaThe same steps make the same thing every time.
How it works
Ravi's steps were blue block, yellow block, green block.
Bo did the very same steps twice, and the two towers were twins.
The same steps from the same place give the same result, every time. Different steps can give something new.
Bo's tower steps.
Example 1: Twin towers
Bo follows blue, yellow, green.
Ravi says again, and Bo follows the very same steps.
A second tower stands beside the first, and they look just the same.
Example 2: New steps
Ravi says green first, then blue, then yellow.
Bo does just what he is told.
The new tower has a green block at the bottom, and the first two had blue at the bottom.
Example 3: The same walk
Bo runs these steps on the board: forward three times, turn left, forward.
He lands on the star.
Run the same steps again from the same start, and Bo lands on the star again.
The same steps, the same walk.
Example 4: A machine for steps
Bo is like a machine for steps.
Same steps, same start, same result.
Words to know
same
Just alike.
steps
Things for Bo to do, in order.
order
What comes first, next and last.
different
Not alike.
Watch out
A changed step, an extra step or a missing step can make something new.
Steps in a new order can make a new tower or a new walk.
The start counts too: the same steps from another place do not give the same walk.
Try it
Bo does the same steps twice. Do the towers look the same?
Ravi says green first, then blue, then yellow. Which block is at the bottom?
Is green, blue, yellow the same tower as blue, yellow, green?
Bo runs the same steps from the same start. Does he end in the same place?
Answers: 1. yes · 2. green · 3. no · 4. yes
Try at homeMake up three silly steps, like hop, spin, tiptoe. Do them with a grown-up and see that it comes out the same each time. Then change one step and see what is different.
For grown-upsBuild a tower of three colored blocks from a list of steps and build it again from the same list to see it match. Then change one step, and let your child say what is different.
