| Place value mat. |
Spread the mat in front of the child.
Explain that the letters on the top represent:
Units
Tens
Hundreds
Thousands
Units
"If we had one more unit...we would have ten."
Tens
Do the same with tens.
"One Ten, Two Tens, Three Tens..."
"If we had one more ten...we would have one hundred."
Exchange each time you move to the next place value. You can use an exchange tray.
Hundreds
Start counting out hundreds in the hundreds column.
As hundreds are counted, stack them on top of each other as if building a thousand-bead.
"If we had one more hundred....we would have one thousand."
Thousands
Exchange for the thousand.
*Note: don't refer to the shape of the beads (bar, square, cube,) as this might confuse the child later.
Math (ECE) Fall, pg 49
Units
Place the units one by one in the units column and have the child help count. "One Unit, Two Units, Three Units, etc..."
Place them vertically until you reach nine. Do the same with tens.
"One Ten, Two Tens, Three Tens..."
"If we had one more ten...we would have one hundred."
