Board of Eykleides

Draw a large square table.

Divide the square table into 12 vertical columns and 12 horizontal ones.

Color the table. We choose the cells in the first horizontal column to be different in color from the rest of the table. We do the same for the cells in the first vertical column.

In the first cell on the left (left corner) write the multiplication symbol (X).

Then write the numbers in the remaining horizontal cells from 0 to 10.

Do the same in the cells that are located vertical and left: number the cells from 0 to 10.

Then multiply each number in the horizontal column by the numbers in the vertical column and add the resulting number to the corresponding cell.

Finally, cover the board with a plastic sticker membrane.

(for the second panel)

Draw a square table.

Divide the table into 4 horizontal parts and 1 vertical (on the left side of the table).

Write the letters A-B-C-D in the cells on the left and color them in different colors.

Color the rest of the table with the same color.

In each section of the table, horizontally, we write the multiplication exercises: 1 x 1 =…, 2 x 9 =…, 1 x 10=…,

Finally, cover the board with a plastic sticker membrane.
