With the special marker, you WRITE the correct answer, without "fearing" the MISTAKE!

With the brush that is on the cap of the marker, you ERASE what you wrote. You WRITE AGAIN and PRACTICE many times to become the BEST!

With the book of NUMBERS from 1 to 100, our little friends – especially first graders – UNDERSTAND, LEARN, and PRACTICE:

• In oral and written counting from 1 to 100
• In counting by 2s, 5s, and 10s up to 100
• In comparing numbers using the symbols: >, <, =
• In breaking down two-digit numbers into sums of units and tens
• In horizontal and vertical additions and subtractions
• In mental calculations
• In using and exchanging euro coins and cents

Additionally, they learn to find:

• The value of digits according to their position in a number
• Sums and differences in the number table from 1 to 100
• The half and the double
• The odd numbers and the even numbers
