Measure the butterflies!
To use this package laminate and cut out the butterflies.
There are two versions in this package, one with black lines to show where to measure, and one without the black lines.
I suggest placing the set you want to use around the room and having students take their recording sheet and ruler around to measure the height and width of each.
You may choose to have them measure to the nearest cm or mm, or inch or quarter inch. Two recording sheets are included, one with estimation and one without.
