Transparent measuring cups and spoons 1ml 10ml 100ml A set of 3 for educational purposes. I bought these to help with educational play. There are educational toys for measuring experiments, but the transparent ones are easier to understand the volume, and it's better to have accurate measurements (overseas measurements are different, such as in ounces), so these are Korean products. They are for cooking, so the measurements are accurate. You can find items over 200ml by searching for things like "polypropylene beaker with handle," but there aren't many that have 1 deciliter = 100mL, which is first learned in the second grade. Unlike length, volume is difficult to visualize, so when learning about volume, it's good to understand that 1mL and 10mL are about this much, and then 10 times that is... I think it's good to learn while playing and actually pouring and transferring. Since it's the level full to the brim, it's easy to play with in the bath◎ Of course, for elementary school students learning about units of volume, it's also good for toddlers to experience volume through bath play, colored water play, and sand play◎ I also sell other Montessori-related and educational toys.
