逐吋直尺

My nephew loves using this to measure everything around the house, and the side-by-side inches and centimeters have helped him understand both systems. It's sturdy enough for a four-year-old's hands.

The clear plastic makes it really easy for my daughter to line up the edge of the page and see both the inches and centimeters at a glance. It’s sturdy enough for a four-year-old, and we’ve already used it to measure everything in the kitchen.

My first grader loves that both inches and centimeters are on this ruler, so she can practice with both. The markings are clear enough for her to read without help.
