Measure to the Half Inch: what children learn
A ruler has a long mark for every whole inch and a shorter mark halfway between. Kids read the whole inches first, then add 1/2 inch when the bar ends on a half-inch mark.
Measure to the Half Inch: worked example
A bar ends at the half-inch mark just after the 2 inch mark. How long is the bar? 2 1/2 in
The bar goes past 2 whole inches and stops at the next half-inch mark. That makes 2 and 1/2 inches.
Measure to the Half Inch: a common mistake to watch for
Kids sometimes read the half mark as a whole inch and write 3 inches instead of 2 1/2 inches.
Measure to the Half Inch: how to help at home or in class
Cut paper strips that end on whole and half inches, and make a masking tape ruler with a long mark for each inch and a shorter mark halfway between. Your child says each length in words, such as two and a half inches, before checking it against a real ruler. When the half mark is never read as the next whole inch, try the quarter-inch ruler.
