Contains two each of the unit bars from l-9 and cards with addition and subtraction facts – control of error on the reverse.
The following video shows how very young children are able to understand the concept of addition and subtraction by using this kit.
Not shown in the photo below are the decks of addition and subtraction cards that come with the kit. The student who worked this problem became somewhat overwhelmed when there was more than one card in the tray at a time so we put the decks of cards and a ten bar outside the tray and used one card at a time and the ten bar as needed. We were able to finish quite a few problems this way. Not only did he love it but his confidence and skills grew quickly with the use of this kit.
