laajennusjakoja
Laajennusjakoja refers to a concept in Finnish mathematics education related to division problems where the dividend is larger than the divisor. This pedagogical approach aims to build understanding of division by breaking down larger numbers into smaller, more manageable parts. Instead of directly calculating the result, the focus is on decomposing the dividend into multiples of the divisor or into simpler numbers that can be easily divided.
For instance, in solving 75 ÷ 5, a laajennusjako might involve thinking of 75 as 50 + 25.
This approach is particularly useful for introducing division to younger learners or when dealing with larger
