Double Digit Group Division

Home > Wikisori Albums > Mathematics > Double Digit Group Division

Given a division problem, the child prepares the stamps and the skittles.
Since we want to do a group division, we put the skittles together in a group.
Directress asks: "How many groups of 26 can be made from this number?"
The child places two tens and six units in a row, continuing his distribution by making all horizontal rows of 26 in a column.
The stamps are always placed in hierarchic order.
Here, the skittles serve only as a reminder of the number in the group.
This time we will first make groups only of tens.
Groups are made of two tens and lain out in rows.
Directress asks: "How many groups of ten did I make?"
"So that each group has 26, I must make the same number of groups of units".
Groups of six units are made in rows that line up with the groups of ten, yet in a separate column.
When the child finds that more units are needed, one group of tens is returned to the dish so that they may be changed.
Directress asks: "How many groups of tens do I have ? 4. How many groups of units? 4 is our answer".
