Work card for strip board for subtraction

The ideal help for subtraction with tens crossing. The work card with integrated self-control makes it easy for every child to learn all the subtractions of the strip board quickly and easily. The work cards have different levels of difficulty and help to thoroughly practice subtraction.

With the supplied dividers, the child can divide the tasks according to difficulty. If a task is solved correctly, it goes behind a separating sheet and is repeated the next day. If it is correct again, it goes behind the separator sheet for the next week's repetitions, and so on.

Instructions for the task cards for the strip board for subtraction

The wooden box for the work index contains five dividers. These can later be used to form six compartments into which the cards are classified. Correctly solved task cards from a subject are placed in the next subject at the back.

The exercise cycle can either be chosen freely or look like this:

daily: 1st subject

every 2 days: 2nd subject

weekly: 3rd subject

every 4 to 6 weeks: 4th subject

every 8 to 12 weeks: 5th subject

at its own discretion: 6th compartment

At the beginning, however, all cards are in front of the first separator sheet (1st compartment).

It is advisable to start with the cards in a subtraction series (9-1; 9-2; 9-3...), later the tasks will be solved automatically in a jumble.

The cards of the selected row are taken out of the box and dealt with in order or mixed. The front of the card shows the task, e.g. 9-7=

The child matches these with the strips on the subtraction board. With the back of the card (on which the result of the calculation is printed in pictures and in writing) the work can now be checked and corrected if necessary. If the task was solved correctly, the card goes behind the first separating sheet (2nd compartment), if it had to be corrected, the card remains in the first compartment.

Once all the task cards in this subtraction row have been distributed from the first to the other compartments, the next row is chosen and processed in the same way.

To consolidate the series of tasks (learn by heart), you can later work in pairs or individually with just the cards (without the strip board).
