Hello Venla,

Thank you for pointing this out.
It should read "from the previous lesson in 103" not "on the previous page".

The idea is how partition and measurement problems look on the abacus.

But the picture needs to be changed on the duck one too, because it is 22 ducks.

Thank you for asking so we can clarify to you and fix it in our book.

Please let me know if you have any more questions. You can email me directly at Carissa@alabacus.com .

Thank you for giving your child a RightStart in Math,
