| Helping Your Child Learn Math |
Grades K-2
What you'll need
- A measuring cup, 4 glasses of equal size, and water
What to do
- Pour water at different levels (1/3 cup, 1/2 cup, 3/4 cup and 1 cup) in each glass. Put the glasses next to each other. Ask your child: Are all the water levels the same or different?
- Ask your child questions to encourage comparison, estimation, and thinking about measurement. Which glass has more water? Which has less? How many glasses of water do you estimate it will take to fill the container?
- Pour more water into one of the glasses to make it equal to the amount of water in another glass. Move the glasses around so that the glasses that have the same amount of water are not next to each other. Ask your child: Which glasses do you think have the same amount of water?
- As your child begins to understand more, do activities using different-shaped containers that hold the same amount of a substance (water, rice, and popcorn kernels). This helps your child see comparisons, as well as the various capacities of different-sized and -shaped containers.
Parent Pointer
Filling empty containers provides opportunities to explore comparisons, measurement, volume, estimation, and geometry.
