Bobo Bear spread a blue scarf across the floor and called it a river. His toy duck needed a bridge to reach the other side.
Page 2
Bobo laid one long block across two tiny blocks. When Bobo set the duck on it, the bridge tipped sideways and landed softly on the scarf.
Page 3
Bobo felt a little disappointed. He hugged the duck, took a breath, and looked at the wide blocks and narrow blocks again.
Page 4
He placed two wide blocks flat on one bank and two wide blocks flat on the other. The wide blocks made two strong, flat sides.
Page 5
Next, Bobo stacked one square block on each base. He checked that the two short towers were the same height.
Page 6
Bobo laid the long flat block across the towers. He pressed the middle gently, and this time the bridge stayed still.
Page 7
Bobo slid the toy duck across the bridge, crossed the blue scarf, and reached the other bank without tipping anything.

Bobo cheered. His first bridge showed him what to change. Wide blocks underneath helped the new bridge stay still.

Bobo builds a block-road way
For his yellow duck today.
At a gap, the wheels must stop.
How can duck roll to the top?
One long, wide block reaches through,
But standing tall will never do.
Turn it, test it, make it flat.
Can it bridge from this to that?
Tap it gently; does it stay?
Careful tests can find a way.
Bobo turns the block around,
Lays both ends on steady ground.
No big wobble, no big shake.
This is one strong bridge to take.
Turn it, test it, make it flat.
Now the duck rolls over that.
Every wheel stays safe and true.
Bobo cheers, “My bridge works too!”
Try another way when plans feel wrong.
A careful builder makes things strong.
