Learning Resources Rainbow Fraction Liquid Measuring Cups. Make learning to measure easy and fun with the Rainbow Fraction Liquid Measuring Cups. These colourful food-safe dishwasher-safe liquid measuring cups offer a hands-on way for children to learn measurement concepts such as volume capacity and fractions while cooking or engaging in imaginative play. Plus the nesting design means they can double as a stacking toy. The cups are colour-coded to the Rainbow Fraction Teaching System - whole (red) half (pink) third (orange) and quarter (yellow) so it’s easy to find the right cup. Large easy-to-read printing is scratch-resistant and features imperial and metric measurements. Soft easy-grip tops with pouring spouts and spill guards at the bottom prevent messes and keep the cups stable. The set includes 4 Measuring Cups (1 cup 1/2 cup 1/3 cup 1/4 cup) and Activity Guide.
