This wooden addition and subtraction board is dual sided and an original to Jack and Link and has personally been used in our own household. We included math facts up to 12 since most curriculums cover math facts from 10 to 12.
Our dual sided board has two viewfinders, one for subtraction and one for the addition, that allows the child to focus on one line at a time.
- You can slide the viewer up and down and focus only on one math fact at a time.
- The slider has sides that prevent it from slipping off the side of the math board so it'll stay on the line you wish to focus on.
- The viewer is not attached to the addition and subtraction board and can be stored away when no longer needed and then you can use our display stand in conjunction with your wooden board as a visual so your child can easily reference it when needed.
- Allows for independent work by allowing the child to independently check their work using our double sided addition and subtraction board.
We used organic maple hardwood for our dual sided board and cherry hardwood for the viewfinder. All pieces are conditioned with organic white bees wax and organic coconut oil.
